Bob has to be the real deal. Looks like he raised a good kid.
I'd would never have talked to my father like that.
I truly appreciate all your videos. I saw how proud you were of your son. He will be fine. I am 62 years and a 100% disabled Vet from A.F. I had a great time and started learning how to solder and weld while I was in. Refrigeration Shop. He will do well sir. Again, Thank you for all your instructions.
1st and only time I used silver solder was in tool and die school. Soldered high speed steel tips onto cold rolled steel for boring bars. They are still holding up 10 years later. Good stuff.
That scuffle between you and your son was awesome example of give and take. Thanks gents.
I am so very impressed, with ALL YOU DO, when I started in this industry in vocational school in high school, these are the things we learned how to do and it doesn’t seem like they show or teach the stuff a lot anymore, I love the old-school ways and the way you conduct yourself. So I just want to say thank you for what you give back to the industry.
In a pinch I once silver soldiered a clothes dryer element and then ordered the replacement to make the full repair later on. It ended up outlasting the dryer itself, I never did put the new part on. Great video.
Bob, thanks for another great video. Tell your son thanks for his decision to serve our country.
Used it all the time on copper pipe back when I used to install a/c systems. Cool video!
Would this technique work on a chainsaw exhaust?
Great for refrigeration copper tubing.
awesome video Bob. Simple and to the point. Good to see the young ones being productive even if they are lippy and disturbing the tools.
lol love Tombstone! Seen that movie about 50 times! Thanks to your son for serving our country. respect!
Thumbs up for your son's service. Thank him for me and mine.
God bless you on supporting our military! From one vet to another, thank you!
Haha! We have the same yard tool and it broke exactly where yours did. My husband drilled and tapped it and it’s still going three years later! All of a sudden they’re ready to go , and they don’t visit and call as much! Good luck to him-go active!
these videos really help to see the everyday applications that can be done. Thanks for all your videos.
Great video
I have been using brazing techniques for years. In the Refrigeration industry I either braze with sil flos or silver solder.
Best rule of thumb is copper to copper is sil flos.
Copper to anything else is silver solder.
Thanks for the feedback. Good intel.
How's about stainless to steel?
Stainless to carbon steel can be done with a 56% silver brazing rod with a paste flux
There’s so many different kinds of flux. Can you use just regular flux found at a plumbing supply store?
Just make sure it isn't soldering flux. You want the white paste flux in the plastic jar. There's a ton of different brazing alloys too. Only a few seem to be available to us every day folks.
en.wikipedia.org/wiki/List_of_brazing_alloys
Thumbs up for the "go heels" Tombstone quote. It's like your working with your brother's kids or something
nice
Can you name off the Silver Solder rod types and the Flux , possibly leave links ?
Really great video regarding silver solder! Great young man assisting as well! As a sales person for the welding industry, your videos really help EVERYONE- I'm a huge fan and will continue to be!
Nice video, very informative. I'm enjoying these videos on the brazing and oxy/acetylene welding very much. I think every welder should learn the o/a and the brazing before the stick, mig and tig. O/A is real welding. Once you learn that, the rest is easier. Just my opinion. Thanks Bob for these vids. Dan.
Oxyacetylene was what attracted me to welding in 5th grade im 33 now and I have done all the welding processes SMAW, GMAW, GTAW, FCAW but out of all of the faster processes I still prefer Oxyacetylene became sort of a expert in it controlling the weld pool and the torch.
I got my 1st job cuz I could gas weld, braze, solder. One person said we should learn this 1st, he,s correct. Nice video
Man I love this channel
More silver and brazing videos, Please.
long time viewer, first time comment. thank you sir for all the time and energy put into your videos. I am not certified but not many of us in the fencing and gate industry are. therefore I appreciate the diversified non opinionated education I find on your channel and have used things here and there to become a better welder. I charge more for my welds than I used to
and I believe I owe a thanks to you and a few other you tubers. thank you sir -Cody starline fence and gate panama city beach, fl
You and your son are wonderful. Thank you for the wonderful video.
I’ve never found a solder with the capillary action that silver solder has, great video and a good dad.
This was a great video Bob. I was searching for info on silver soldering carbide tips for turning tools and am glad you had a video. I really like your logical straight forward way of approaching projects. I have watched many of your videos and have learned from them all. Cheers
look up stephen gottswenter channel. hes a machinist in germany and has a video on what you describe. i might thavespelled his name wrong but its close enough to find it
Thanks for the guidance and great to see you and your son having fun. My son and I joke around a lot too.
Great stuff! More silver brazing please, perhaps show its limitations too. Awesome belt buckle!!
LOVE THIS! THANKYOU FOR EXPLAINING AND SHARING!!
Thank you very much! Awesome skills.
Love the tombstone quote 😎👍🏻
Sweet video. Oh, and I caught the "Tombstone" reference....
nice little repair. thanks for sharing you many years of expertise.
About to fix my mother's broken silver service set; two handles need to be attached to a bowl. You popped up as the first You Tube on 'silver solder'. I learned a lot and you demonstrated the basic process. Thanks. Of course, I'm going to roll with the Craftsmen MAPP yellow home gas and Ace hardware alphaFry #53982 Specialty Soldering Kit featuring silver solder solid wire and flux. Seeing as how I am clueless and have a tremor, I think all will be well and the repair will be successful.
You have a fine son and I hope the Army bit works out. (ex Air Force, myself.)
I have worked with silver solder and flux for many years. Orthodontic appliances are made with silver solder, stainless steel, solder, a superfine torch flame and human hands. The appliances are extremely durable.
First video I watched and it was amazingly clear and educational. Thank you Sir.
Ha... didn't expect the Tombstone runthrough. My favorite western :)
Just what I needed...got to fix up a tiny leak on the vaporiser tube of a kerosene lamp. I'm thinking bit of flux, silver solder rod and run it in. My Dad was a welder, wish he was still here !
Bob I do lots of silver soldiering for my model engineering steam engine’s and I only use a very soft flame held about 2” away from the job and wave it back and forth then all of a sudden the flux starts to go watery and shiny then touch the silver soldier on the job and then it flashes around the part it even flows up hill. I started when I was your son’s age now I’m 82 yo. I would use that flame you used to do brazing on thicker materials not silver soldier because it only burns the flux and it will go black in between the two metals stopping it flowing. Doug in Australia.
You mean I don't get to see the test? Darn (and that was a mighty fine video).
This is very helpful. Thanks. Your handsome son obviously has a future. Congrats.
I broke the inner cable of my dremel extension and just silver soldered it for a temporary fix while I waited for a new cable to come in the mail, that was more than a year ago and it is still going strong.
You make it look so simple
Great video. Here are couple additional details for the viewers: Soldering and brazing are essentially the same technique. The difference is the temperature. Above 830 degrees F it's brazing, below is soldering. The MAIN difference is that in brazing the surfaces are hot enough to burn off the oxides off, hence much less surface prep is required. In soldering the surface prep is very important, because metal does not get hot enough to burn off oxides and other gunk.Usually silver solder has up to 8% silver content, while brazing rod goes to 20%. In AC industry brazing is required for R410A systems, because they run at higher pressures.
In my work life i silver soldered copper alloys used in resistance welding applications . A tough one is a scintered material of tungsten and copper , hard to "wet" and too much heat causes tungsten to precipitate to bottom of weldment . Another tough one was induction heating coils made from rectangular copper tubing .
love the relationship. will watch for more vids.
Nice to see you add in the homage to Tombstone in your banter.
Nice video and presentation- thank you!
2:25 is that a tombstone reference? Ha love it!
One of the things I thought was really neat is how high of a tensile strength some sodders can have when i thank of solder i immediately think of circuit board solder
is very useful to know about such techniques it can get things back on line know all the processes including gas welding and soldering techniques
well described thankyou
Really appreciated your instruction. Can you explain when to use regular solder and when to use silver solder?
what's shown in the video is considered brazing because the base metal was above 840°F.
the difference between soldering and brazing is filler melting temperature, base metal temperature, and tensile strength.
both soldering and brazing use capillary action but brazing filler can also be built up to fill gaps if needed.
brazing works great for steel and similar metals, but not so much for copper.
I prefer soldering with *silver bearing* solder over brazing when dealing with copper, the copper surrounding the braze joint will anneal and lose most of it's strength.
I suggest soldering over brazing unless you're going to need lots and lots of tensile strength or are placing metals in very hot places like an oven.
I saw the scoop get red hot. I've silver soldered a few things with propane, but unless I'm welding, the only time the parts get red is when I'm brazing.
Good preparation is very important.
I would have fit the handle to the scoop better before brazing, or soldering. The closer the fit the better. The silver will work by capillary action. In my jewelry an invisible fit gives the best strength and a minute use of solder. It is so fun to silver solder, so user friendly.
I've used silver solder to replace front sight on old guns and joining hss shafts to carbide cutting inserts for odd mill/lathe jobs, if also used it for a few other jobs I'd never admit doing while nobody was lookin... The old "looks good from my house" kind of halfassery
My Dad used silver solder all the time and said it was a super strong weld he was a machinist like you said it flows really thin
Not sure how I missed this one... A year ago!!! Hmm. You tube has been a bit sketchy with notifications..
Another great video Bob!!
Thank you!!
Good video Bob would like to see you use silver soldersed again in different applications
Love the video, hug 🤗 your son and tell him you love ❤️ him while you have the chance. Lost one of mine in a car accident, someone went to sleep and crossed the center line. I am a retired welder and I was wondering if a neutral flame would have made a difference?
Soft neutral flame with a small rosebud is best... imo. His fit up on that one tab was too big also. You need a tight fit up for capillary flow to happen.
Thank you, an interesting and well laid out video, regards Doc Cox.
Let's break one of your golf clubs lol! Thanks Bob, keep em coming!
there is a place in my area called TM technologies. he specializes in torch work. lots of brazing, welding, and soldering materials
Silver solder is sadly under rated. I used it for certain repairs on automobiles. Strong and clean.
congrats to your son and yourself and best of luck in military service. go army.
Thank you.
That's a real shop. Tile Walls. You know what you are doing.
Thumps up for that belt buckle! #BOOM
Bob, nice demo for newbies. As I'm in an HVAC&R trade person, I would have to say your techniques are lacking concerning silver soldering/brazing. If I have the chance after this "Covid-19" scare goes away, perhaps a person such as myself can show you a different way of silver soldering, and properly. That metal should have never been "red-hot". Feathering a torch is an art, and takes practice. You heated that stainless entirely too hot. Just my 2ç.
Silver solder is great! There's all kinds of it. I've had trouble doing this on stainless, got it overheated or something, maybe didn't clean enough first. I'd love to see some close-ups of this while it's happening. Have had good results with blue or other (Tin Man Tech) lenses that take out the sodium flare so you can see better. Yeah, the number one thing about this stuff I think is working dissimilar metals, that comes up all the time!
Using the correct flux and cleaning are important for a good joint.
I have had good results on stainless using Harris Stay-Silv Black, it seems to remove the contaminates and oxides better than other fluxes and tolerates the higher temps required for getting a good bond on stainless.
A coworker swears by MuggyWeld and to be fair his final product looks good and seems to hold together, but I do not have any firsthand experience.

Hey, I tried the Black flux, it worked the first time! Looks funny in use, but when I washed it off the stainless looked like new. This is with Stay-Silv 45 and regular 304 stainless, and a big honking Harris air propane torch. Will try tomorrow with Oxygen. Thanks!
Cool.
You are welcome.
ALL BUCKLE NO KNUCKLE
Great vid and informative,Thanks
having a bit of braze around can save you money and time. Its easy to do and you can get a more then acceptable repair on many objects. The best one I did is repairing a really old lock (100 years old) for a door to some closet or something. Exact fit when I was done, its strong, and they did not need to remake a door or hire a carpenter. Easily saved someone like $1000 (some home owners don't accept a solution that does not match the decour for custom stuff).
my first day at my first job in a sheet metal shop - 'can you silver solder?' the foreman says. yep, I sure can... on that job for the next 5 weeks, silver soldering m10 studs into 6mm mild steel plate. I did over 900 of those plates, each with 8 studs in.
Another great video.Didn't know silver solder is 70,00psi.
Great video Bob..... Thank you
What's the difference between this silver solder and silphos 15? Ive gone through pounds of of solphos 15. Sometimes ill go through a couple pounds of it in a day. It's what we use to join our medical grade copper pipe in hospitals and labs. We have to fill the cup 100% then I like to cap it off. Those 4"Ø and 6"Ø lines will just drink that stuff til they're full. Of course we keep a nitrogen purge going inside the pipe the whole time to displace the air so copper stays nice n shiny..
thank you for these videos, keep up the good work!
Fitting ends to motorcycle cables silver solder is the only thing too use.
Bob, looks like you've raised a fine young man.
Mention SS comes in preformed rings also map gas works great also to control heat. Use at work in production environment
Thanks! I need to repair the headlight rings on my 1930 Packard
Nice video sir,.
i like the way you and your son,interact, it really shows...again like i said.nice video,and thank you,i subscribed and liked and look forward to more videos.....
Good video! I am always puzzled by the dislikes! What is there to dislike about what I consider honest effort on your part?
Thanks, great information!
Couple of things: First - I got the reference to Tombstone immediately. (I think it's actually, "get the bulge on a DUB like you," not TUB.Second - was this real silver solder - you know, with the majority component real silver? The reason I ask is that I've done a bit of "silver soldering" with the stuff you get at the welding supply shop, and it works ok. On a whim, I ordered some real silver solder and was amazed to find that it would easily solder chrome plated items and stainless. Maybe the other will, too, but I was blown away to see it wet the chrome.
thank you for the information
How would you recommend soldering a leg back onto a silver tea pot? I can see they tried repairing it with putty but since I told my partners mother in law I weld for a living she gave this to me to figure out lol lowes doesn't have much if a selection I got the spray on liquid flux and just regular electrical soldering wire
great video. thanks for sharing. pete
I had no idea Kevin Costner was a welder in his spare time.
Will silver solder be strong enough at temperature for automotive exhaust fittings, not at the manifold?
IVE GOT A REAL SMALL TIP IN HERE
I fixed that exact tool with my Mig welder and even on the lowest power setting it did burn through the inside. I had to sand it. It was probably my fault. :)
Sweet! I need some soldering advice/tips.
Cool stuff! I do a fair bit of stainless steel brazing using the Harris Stay Silv blacl flux and 56% silver solder. Mainly I braze AN fitting ends onto stainless tubing for fuel and hydraulic apps. It works well, looks really nice, and makes clean, leak-proof joints that are as strong or stronger than the tubing. What more can you ask for? :-D
is that the same soldier you would use on electronics? awesome video!! love the chanel.
I've never used this product on electronics.
Bob, I'm a firefighter in a rural Montana community and I have a broken piece of cast aluminum (½" thick 1" channel shape) that I need to fix .. In a perfect world I'd have an AC TIG setup, or even a spoolgun, but I don't .. I do have an O/A torch and a old Miller dial arc stick machine .. Any suggestions ??
replacement of part would be $3-400 ..
I have successfully brazed cast aluminum in the past. I wonder if your part can be done that way? If not, you may have to take it to someone that can tig weld it.
silver solder some carbide tool bits?
i wish i could like this comment 10 times
why don't i just have someone do my machining for me? then i can try to convince my wife to wipe my butt as well...
The Moto fixery on some of the huge saws and planers at lumber mills the carbide teeth and blades silver solder/brazed in place. It's amazing how strong it can be when done right.
Sir thank you for the video I absolutely love brazing but I do from time to time find the need to silver solder the problem I face is I don't know what brand silver solder to buy I don't know what's good I don't know what's junk there are so many fake silver soldiers out there that are labeled in a manner to mislead you and I need help to figure out what is a good reputable brand that I can count on and a good amount of silver to always demand that my silver solder contains if you could help me with that I would be very very grateful I know this is an old video I hope you see this either way have a great day
Interesting as ever Bob -but why not spot weld the part as original (but better !) ? Cheers
Steve Peat I don't have a spot welder.
Why not glue it? Why not tape it on there? Why not pop rivit it? Why not heliarc it? Why not mig it? Why not stick weld it? Why.........not silver solder it!
