Jody, thank you for taking the time out of your schedule to come up and visit. It was so much fun and I learned a ton. Thank you for all that you do for this community!
I was a tig welder at a titanium bike factory in north Cambridge Massachusetts in the late 90's early 2000's . You're doing beautiful work. Keep it up!
I just started working with titanium tubing, (aircraft structural) and it is a DREAM to work with, once I got past the quirks of the material, it really is an awesome product to weld. and the BBW cups (in Pyrex) made a huge difference. It allows light to spread out more, and I can see what"s coming around the curve of the tube. I have really started using titanium anywhere I can. It makes the project run over budget, but in my opinion, the weight saving and strength are worth every penny. And you don't have to be nearly as worried about stress fatigue, which brings peace of mind, especially knowing someone's life is on the line at 3000 meters altitude. Thx for a great video.
When I was young there was a race car driver named Juan Fangio and he was simply the best! The reason I mention that guy is that he said "you win the race by going as slow as possible", meaning fast enough to win but slow enough to keep the car intact.Welding is quite similar,you want to weld as cold as possible to get away from enlarging the grain structure but hot enough to get the penetration required
Hey Jodi, Thanks for all the years you have been putting into your RUclips Tutorials. I have been watching for many years. I have been welding for 20 years now and I still look for you to learn something I can apply to my jobs. I love the clear arc shots and the chilled out narration. Thanks man.
I think fusion is the most important thing to consider when welding. It is one of the main reasons Carbondale frames don’t have high failure rates. They have these huge welds both for fusion and aesthetics. Excellent video thank you!
@@eduardosampoia5480 you could NOT be more wrong .. welding is an ARTFORM like anything else that requires skill .. the better you are at it the better the results .. " follow the instructions " .. yeee i read how to setup a welder .. now i can weld as well as anyone else .. no matter how long they been doing it .. you get my point or?
Jody Sir your recent videos are about the best, most informative, welding videos I've ever seen. At 54 my eyes are starting to give up on me so seeing my puddles are tough on these exotic metals. But I'm a poor working class man so there's no giving up. So if you'll keep helping I'll keep hanging in there. BTW I own 4 or 5 of your TIG fingers. I won't buy the knock off brands as a matter of principal. It's you product. I've had my product stolen, rebranded and sold as someone else's product I know how much that sucks Sir.
I'm 64 with rotten eyes but I can still weld thanks to electronic helmets and cheater lens. Cheaters are stereo magnifying lenses. I use a +3 diopter cheater and am about to have to go to +4. Another tip is to illuminate the work to be almost as bright as the arc. I use this light. www.neon-john.com/Misc/Mega_light_home.htm And a smaller but just as bright LED version. The Mega-Light uses a 1000 watt metal-halide bulb. I'm trying going back to a conventional non-electronic hood. It's working pretty well. I can see the work before the arc is struck. For welding in tight spaces, I've made a 175 watt metal-halide light out of a conventional drop light. There is a version of the 175 watt bulb that is the same size as a 100 watt incandescent lamp. I polished the reflector to get more heat and light out the front and less heat out the back. There have recently become available LED lights of equivalent brightness that will fit in the socket. I have one on order. Extremely bright illumination is vital for us geezers to continue welding. John
I’m late but that MIT professor is Thomas W Eagar on youtube. He does welding metallurgy lectures that are available to anyone. Just search up Thomas Eagar. The specific situation he talks about is GE did some laser welding on $25,000 parts. If it fails, they throw away $25,000, if they succeed, they get $50,000. They were cleaning their parts with industrial grade acetone and were getting porosity. Thomas Eagar suggested switching to reagent grade acetone however they just blew him off because it was such an odd suggestion. Well after a year of failed parts and hundreds of thousands of dollars in losses, they tried it and it worked.
Neat video. I was a teenager in the late eighties and raced mountain bikes, so I have a thing for titanium bikes. I also took metal fabrication (welding - SMAW) in high school. Cool to see the build and get the high points of the process. Thanks!
Noticed the "modified" regulator/hose wrench, you always provide ideas that help our effort. Plan on making one today! Thanks for the good information and wonderful - "Tips & Tricks!"
That is one very informative video (even more than your usual, high quality content) Jody; and Mike seems like a real nice down-to-earth guy and a great craftsman. Those welds you guys show are pure art!
After watching just the first 4 minutes of this it became vividly clear that you need to know a whole lot . . .and lay out a lot of money to get started in this game. The "Fake it till you make it" philosophy wont cut it here, that's for sure...
Thank you both for your time and knowledge, the reality is I will likely never weld Ti, but if I do, at least I have a little foreknowledge to do so with.
speedbuggy16v I thought the same thing until I needed to weld some Ti cookware to better strengthen it for my cooking gear in my bug out bag. Turns out it was smart studying about Ti welding and very smart in getting a better welder than I needed when I bought mine. I went with a Dynasty and I am glad I did!
Really interesting video to watch and thanks for posting. Mikes doing really well but has a way to go before his welds are as neat as Seven Cycles or IF bikes. Darren Baum was about the same when he started but now his welding is up there with the best as well. Can't begin to imagine how much skill and practice is required
Your work is excellent, both of you! Those fitups and beads were immaculate. I'm just beginning to dip my toe into the world of titanium and there is plenty to know. Thank you for sharing your expertise and experience!
Great coverage! Yeah, MSDS on acetone says it contains trace oil. That used to give me fits. I find drugstore alcohol works fine for cleaning. Sometimes I will use something stronger like acetone, but clean any residue from that with the alcohol. Reagent grade might be the solution, if I can find it. Just remember no brake cleaner, it will fry your brain.
Tom Suggest you get a good TIG like a Miller or Lincoln inverter, a top end helmet and have at it! No better way to learn than your screw ups. Once you are a doc you will have a lot less time on your hands. It’s fun as hell to be able to weld almost everything!
Thanks for sharing all your secrets... I shall set up a workshop tomorrow using Diy tooling :P Just kidding, great video on an excellent topic. Its great to see the passion and the high level of OCD/Attention to detail !
Juan Fangio(perhaps the best formula one driver ever) once said "to win the race you must drive as slow as possible",as far as welding goes I try to weld as cold as possible (meaning don't overheat the base material!)...I somehow see a correlation between the two!
Beautiful stuff. What is the TIG welder setup? I've worked as a weldor in the past but many years ago. I see leaps in welding technology and would like to get back into it for my own good. Always loved the work, the employers, at times, not so much. I have deep respect for guys like Mike. Thanks for the vid
Great stuff man! Im a stainless steel welder venturing into exotic metals. I always thought if possible to weld in one pass to keep from burning all the properties out of the metal also to not have any weaknesses in the heat effected zone?
Was really into BMX racing back in the day, actually what got me into welding. Aws asme ix certified on stick decent at tig but still practicing. Would love the opportunity to try this out
Since youre certified on stick....if my stick keeps sticking what do I need to do? Change angle? Approach slowly and glide? Increase amps? It's a old inverter harbor freight tig stick, from maybe like 2003 or so. I've seen it make nice stick weld with an experienced welder but he was just a passer by. What is your trick?
@@thornyturtleranch4u what's rod type, diameter of rod, amperage now, material thickness your welding on just a few quick questions to point you in right direction
@@chrisjones6165 I'll get back to you on the rod. I think it was the 6000s number but I know there are a few. Maybe the 7000s I'll have that later today. It was quarter or thicker, welding a crack in a tow hitch plate. My weld held but it cracked again elsewhere. Took forever to get each weld going.
@@chrisjones6165 6011 is what I was trying. It kept sticking before I could get a good burn or arc. I upped the amps which maybe helped but I burned through my 1/4 inch plate and had to patch it but I got plenty of experience moving it around real fast to let molten metal cool before dripping while I added it elsewhere patch a hole. When I got it burning I knew what to do, just so hard to keep it from sticking.
How about making gloves with a tig fingers built in? I can imagine a palm of a glove made out of the same material could save a hot hand when positioning large items that have been preheated or part welded?
from what I can see, Mike Zanconato is probably using a kevlar glove. I had read on Anvil's website (the company that makes the fixtures that Mike is using) that they recommend using kevlar gloves for welding. Here is a quote from Anvil's site. "For welding steel or ti, I use the Golden Needle Kevlar gloves (Enco part number 505-4135). These are a lighter glove, they’re gold in color and they show dirt well which is a good thing when frame building. They’re washable. They last a looooong frickin’ time (months). They don’t absorb oils unless you’re serious about it. They fit your hand well if you have average size hands. They don’t burn unless you do something really stupid and if you do something really stupid, they won’t shrink on your burning fingers like leather gloves do. They also don’t conduct heat and this is important if you have a “dang near holding the cup” welding style like I do. They cost less than $4 a pair if you buy $40-odd bucks worth. IMO, they are vastly superior to any leather glove (and I’ve used them all) for Tig welding." I havent been able to find some of those gloves locally, I really want to try them out. For now I'll keep using leather gloves and the Tig Finger.. But I think the Tig Glove could sell like hot cakes!
Oli Aponte I looked up Golden Needles Glove Company and see they were making gloves on a massive scale but I don’t see a website and wonder if they are out of business now. Maybe Ansell or another company bought them out.
I have 2 questions and a conclusion about this video: 1.Where can I find any titanium stuff like tubes, hardware, chunks etc??? 2.Is those Anvil Bikes jigs ideal for fabricating custom-built chopper motorcycle chassis??? 3.Those welds look awesome.
Perhaps a silly question but how when purging inside a sealed tube do you avoid the purge gas blowing out the weld when getting close to finishing the weld and closing up the only remaining gap?
Not gonna lie brother I was very turned off by your some of stuff when you first came out but your skills have definitely increased. And I can only say so much because I have no channels/video's so who am I to critique.
Can you make a film on heavier industrial fabrication although this may be for mig or arc welding.Titanium is very hard ,if you have a real thick piece whats the best way to cut it? Good welding.
arethe bronze chill inserts homemade or store bought ?? how about pure ethyl alcohol vrs pure acetone for final clean ?? SUPER VIDEO THANK YOU BOTH !!!
I made the heatsinks for the head tube and seat tube, but the bottom bracket heatsink is a Paragon product. You can use different alcohols for prep. Isopropyl is probably most common.
What was omitted is where to buy the acetone and what does he use to apply the special reagent grade acetone. How much more does it cost vs home depot acetone.
Nice work! I do the same but for the aerospace industry. Nic, cobalt, ss alloys. I'm curious to know more about your back purging. What cfh are you purging at?.
Same, argon purge slowly fills the volume of the container, so once the atmospheric gasses have been purged you only need to maintain the argon volume, maybe 3CFH or so, going too high will cause positive internal pressure that will blow out your weld. Also remember to leave a vent hole(s) for the atmosphere to escape
Are fusion passes common for thin wall in general, or specific to titanium? I've welled thin wall (0.035 like this, but mostly 0.049/0.058) in the past, but didn't fuse. My experience was 4130, no TI.
Working at an aerospace composites company we found that most of the reagent acetone that we bought was dirty, we received these in 55 gallon drums and believe that the drums they used were not the cleanest. We even had some that smelled like gasoline…
That’s why the term treat every weld like your life depends on it, or someone else’s life, as a welder we hold a responsibility to do the best we can do, this guy is dialed, watch and learn that purge set up with the swagelok, pipe fitters dream set up.
Hi guys, I have a few comments I’d like to make. Cleanliness is key when welding Titanium and I would advocate that you wipe the welding rods with acetone before use. Bike frames are a very low key technology as regards to Titanium welding And presumably you are not x-raying and Dye checking the Welds afterwards to see their integrity. I wouldn’t be surprised with this amount of chill and the two passes that they would have a considerable amount of porosity present. This shouldn’t be a problem in your application though. I am a tad concerned when you talk about dark straw colour - anything darker than light straw is considered scrap in the aero industry and the part is thrown away due to the internal alpha case. The worst contamination is dark blue and the problem with Titanium is that if it is rewelded it will appear clean and good. In reality the weld is totally unfit for purpose and will be very brittle. I don’t agree with the two passes, A decent welder will put these simple joints together with one pass.
Out of curiosity, what alloy of Ti is he using? I am an Aerospace Welder and was wandering if it's anything like we use or if it's something completely different.
Hi great insight in to building Titanium bikes, I wonder if you can answer my question about what is the best Brazing rod to braze T45 to Titanium by gas Oxy Acetylene or Oxy Propane Torch thanks
I would have loved to hear Mike's view on Welding vs Brazing a bicycle frame. That is another debate that continues in the cycling world fueled by couch welder. And the famous, "So I heard from this guy who snapped his bike on (insert random trail)...He bought a welded frame, when he should have bought the brazed frame..."
I think the reason some companies braze them is for automation. They drop a slug of brazing metal into the end of the tube, heat the joint, and it's all done. 1/50th the time too.
Properly brazed joints can be stronger than the pieces being joined, but are not as strong as welded joints. Brazing also has minimal effects on the two metal parts.
I don’t think on Titanium that brazing would be as strong as a TIG welded joint. Brazing is very strong but I don’t think it is 120kpsi strong. Most brazing is 40-70kpsi, no where near what a welded joint would be.
what are those spider web looking marks on the surface of the weld called? I know they are normal but I once had an engineer argue that they were cracks.
dennis miller Spider webbing is cracking but the beads are normal. Depends on which you are talking about. All the shots in this video are beads. No cracking here. Ti and some other metals do form spider web cracks though.
Awesome work! Where did you get that purge setup? Any interest in 1.00 x .21 wall 3Al/2.5V I have a bunch of untouched 16' I'm looking to free up some space?
Yes, the heatsinks are plumbed to carry the Argon, it's a dual-purpose setup. Full purge is the objective. It would be necessary for stainless as well.
Is it really advisable to use a file made of hardened high carbon steel when deburring titanium? I'd image you risk contamination of the titanium and furture welds in it?
There is a line of special files for filing stainless steel, they are super hard, cut for a long long time, and not too terribly expensive. MSC had them on sale a few years ago. Pferd makes them "Corinox" also they don't rust if you leave them outside. There were some on Ebay that I bought in needle file sets as well. Get them, totally great product.
On Jody’s site about Ti welding he recommends using carbide files. I have yet to research them but that would be the best I would think. Diamond may also work.
Most files have oil on them and I’d be afraid of getting burrs and other things from the file to fall off as you file it and thus into the weld. Although one should ss wire brush and then wipe down with acetone after any filing anyway.
You would get good welds with a good vacuum. Problem is getting a good enough vacuum and how would one work in it? It is possible if fully automated but still difficult, time consuming and mostly not practical.
Hi jody when you welding with a tig welder how did you get it that inter cone that white ploom of arc during welding, because when i trying i didn't see at all

I just started working with titanium tubing, (aircraft structural) and it is a DREAM to work with, once I got past the quirks of the material, it really is an awesome product to weld. and the BBW cups (in Pyrex) made a huge difference. It allows light to spread out more, and I can see what"s coming around the curve of the tube. I have really started using titanium anywhere I can. It makes the project run over budget, but in my opinion, the weight saving and strength are worth every penny. And you don't have to be nearly as worried about stress fatigue, which brings peace of mind, especially knowing someone's life is on the line at 3000 meters altitude. Thx for a great video.

Perhaps a silly question but how when purging inside a sealed tube do you avoid the purge gas blowing out the weld when getting close to finishing the weld and closing up the only remaining gap?
harry smtih there is usually a hole on the bottom bracket shell bottom that a screw goes into and holds a cable guide
Not gonna lie brother I was very turned off by your some of stuff when you first came out but your skills have definitely increased. And I can only say so much because I have no channels/video's so who am I to critique.
Can you make a film on heavier industrial fabrication although this may be for mig or arc welding.Titanium is very hard ,if you have a real thick piece whats the best way to cut it? Good welding.
Greetings from Poland :) Weldingtipsandtriks rules!
man this is some useful information precisely delivered - thanks for that!
arethe bronze chill inserts homemade or store bought ?? how about pure ethyl alcohol vrs pure acetone for final clean ??
SUPER VIDEO THANK YOU BOTH !!!
I made the heatsinks for the head tube and seat tube, but the bottom bracket heatsink is a Paragon product.
You can use different alcohols for prep. Isopropyl is probably most common.
What was omitted is where to buy the acetone and what does he use to apply the special reagent grade acetone. How much more does it cost vs home depot acetone.
Nice work! I do the same but for the aerospace industry. Nic, cobalt, ss alloys. I'm curious to know more about your back purging. What cfh are you purging at?.
Same, argon purge slowly fills the volume of the container, so once the atmospheric gasses have been purged you only need to maintain the argon volume, maybe 3CFH or so, going too high will cause positive internal pressure that will blow out your weld. Also remember to leave a vent hole(s) for the atmosphere to escape
Beautiful titanium welds!
Starrett makes very good tools, especially their measuring tools.
Nice work, a joy to watch
Are fusion passes common for thin wall in general, or specific to titanium? I've welled thin wall (0.035 like this, but mostly 0.049/0.058) in the past, but didn't fuse. My experience was 4130, no TI.
Great video. Thanks for sharing. Does anyone have the link to the acetone contamination video he was talking about?
Working at an aerospace composites company we found that most of the reagent acetone that we bought was dirty, we received these in 55 gallon drums and believe that the drums they used were not the cleanest. We even had some that smelled like gasoline…
Excellent video as always Jody
His fitup is beautiful
Hello from Russia!!! Very interesting video!
Thanks for going above and beyond!
Mmmm, stupid RUclips unsubscribed me from a bunch of channels, didn’t know about this one. Very cool Jody!
That’s why the term treat every weld like your life depends on it, or someone else’s life, as a welder we hold a responsibility to do the best we can do, this guy is dialed, watch and learn that purge set up with the swagelok, pipe fitters dream set up.
Fkn gorgeous welds. I like the welds better than the bike. Is that odd?
Jody we would love to have you out to a race. And maybe showing some of the guys some cool fab tricks. Holler back if your interested
Hi guys, I have a few comments I’d like to make. Cleanliness is key when welding Titanium and I would advocate that you wipe the welding rods with acetone before use. Bike frames are a very low key technology as regards to Titanium welding And presumably you are not x-raying and Dye checking the Welds afterwards to see their integrity. I wouldn’t be surprised with this amount of chill and the two passes that they would have a considerable amount of porosity present. This shouldn’t be a problem in your application though. I am a tad concerned when you talk about dark straw colour - anything darker than light straw is considered scrap in the aero industry and the part is thrown away due to the internal alpha case. The worst contamination is dark blue and the problem with Titanium is that if it is rewelded it will appear clean and good. In reality the weld is totally unfit for purpose and will be very brittle. I don’t agree with the two passes, A decent welder will put these simple joints together with one pass.
Hi. Is it better if I weld titanium in a confined room with full of Argon?
What would happen to a titanium bike if you rewelded the crack?
Informative discussion, thanks!
What do you think about how Jesse James welds? You think he’s one of the best?
Out of curiosity, what alloy of Ti is he using? I am an Aerospace Welder and was wandering if it's anything like we use or if it's something completely different.
The tubing is 3/2.5. The wire is 6/4 ELI.
Have you ever experienced oxygen contamination with the pyrex gas lenses? If so, what did you find helped to eliminate it?
what are those gloves he is using? they look like fabric and yet they dont burn near the arc.
They are knit kevlar I get from mcmaster. Part 56125T3. 9 bucks a pair.
zanconato Awesome TY and for giving part number too!
Congratulations for your videos!!! ...I follow you from Nicaragua
Hi great insight in to building Titanium bikes, I wonder if you can answer my question about what is the best Brazing rod to braze T45 to Titanium by gas Oxy Acetylene or Oxy Propane Torch thanks
I like the Richard Sachs sticker on his table.
I would have loved to hear Mike's view on Welding vs Brazing a bicycle frame. That is another debate that continues in the cycling world fueled by couch welder. And the famous, "So I heard from this guy who snapped his bike on (insert random trail)...He bought a welded frame, when he should have bought the brazed frame..."
I think the reason some companies braze them is for automation. They drop a slug of brazing metal into the end of the tube, heat the joint, and it's all done. 1/50th the time too.
Properly brazed joints can be stronger than the pieces being joined, but are not as strong as welded joints. Brazing also has minimal effects on the two metal parts.
I don’t think on Titanium that brazing would be as strong as a TIG welded joint. Brazing is very strong but I don’t think it is 120kpsi strong. Most brazing is 40-70kpsi, no where near what a welded joint would be.
Awesome question btw
what are those spider web looking marks on the surface of the weld called? I know they are normal but I once had an engineer argue that they were cracks.
dennis miller Spider webbing is cracking but the beads are normal. Depends on which you are talking about. All the shots in this video are beads. No cracking here. Ti and some other metals do form spider web cracks though.
Awesome work! Where did you get that purge setup? Any interest in 1.00 x .21 wall 3Al/2.5V I have a bunch of untouched 16' I'm looking to free up some space?
great video boss. very informative
So he pumps the Argon into the tube space close to the heatsinks?
Yes, the heatsinks are plumbed to carry the Argon, it's a dual-purpose setup. Full purge is the objective. It would be necessary for stainless as well.
fascinating. thk you for sharing. I dream of a ti bike, one day, hopefully.
Is it really advisable to use a file made of hardened high carbon steel when deburring titanium? I'd image you risk contamination of the titanium and furture welds in it?
Great Question!
There is a line of special files for filing stainless steel, they are super hard, cut for a long long time, and not too terribly expensive. MSC had them on sale a few years ago. Pferd makes them "Corinox" also they don't rust if you leave them outside. There were some on Ebay that I bought in needle file sets as well. Get them, totally great product.
On Jody’s site about Ti welding he recommends using carbide files. I have yet to research them but that would be the best I would think. Diamond may also work.
Most files have oil on them and I’d be afraid of getting burrs and other things from the file to fall off as you file it and thus into the weld. Although one should ss wire brush and then wipe down with acetone after any filing anyway.
Sweet welding !
I passivate with a Hydraflouric Acid solution when I weld Ti. can never be too clean.
+kbent88 That's some seriously nasty stuff, no?
It is. I hate working with it. It has good results, though.
It sure can help with oxides and other “mill scale” sorta stuff. Beats using a file in certain cases.
Quick question what would happen if you welded in a vacume?
You would get good welds with a good vacuum. Problem is getting a good enough vacuum and how would one work in it? It is possible if fully automated but still difficult, time consuming and mostly not practical.
A lot of critical welding is done in purged chambers-which is much easier to achieve than a vacuum.
superb, awesome video
Hi jody when you welding with a tig welder how did you get it that inter cone that white ploom of arc during welding, because when i trying i didn't see at all
super cool!! I can tig some but this is pure art!!
