If you are interested in TIG welding, you might be interested in knowing when it is necessary to use filler wire and when you can just use autogenous welding. Autogenous welding is a fusion welding method that does not require the application of filler material to form a weld. Jeff Ray, from Superformance Fab, goes over when you would choose one over the other and why.

Loved the vid....looking forward to similar review of lay wire...with various diameter fillers
You got it!
Ohhh h huh job just I uo
the quality of filming gets better and better with every video !
Thanks man im so stoked how its turning out. We have Project Priime on board doing production and just keeps getting better go check out some of theyre stuff on youtube we have a bunch of builds going on. They do amazing work. Thanks for watching man
Great job, Jeff. Excellent video!
Thanks man very much appreciated thanks for watching
Thank you… great presentation
Thanks youu much appreciated
Nice video. I would like to see a video on when you would oxy acetylene weld and when you would fuse weld with it.
Awesome vid as usual!
Thanks man we are putting in the work to try put out highest quality content we can and improve with every shoot we do. Thanks for watching
Welding rod typically has added or sometimes elements removed to make a better weld
YOU DA MAN JEFF.....REALLY ENJOYED THIS....ROCK ON OLD TIMER....PAUL IN ORLANDO
Thanks for all your support Paul.
I like blast tacking Ti and SS, a technique Jody from weldmongers taught a number of years ago
Cool vid, thanks
Good Stuff!
Thank for watching
I did some autogenous welds on stainless sheets about 1/16 thick. Unfortunately I did f up and put two plates in wrong position (one box had two holes against each other and the other one had none). Took a piece of scrap sheet and simulated that weld here. Had a hard time to separate those plates without destroying surface, so I decided to fill that one hole, repolish it and drill one into another part. Saved me a lot of time and suffering.
Thats awesome glad that worked out. There so many tricks to learn when not only fabricating but welding tricks as well. Thanks for watching
I feel like y’all are reading my mind with the timing of some of these videos.
If you ever need anything message us! Just go to our forum www.weld.com/forum
Thats awesome how it worked out perfect time thanks for watching
which welding helmet are you using in the video?
Its the Miller Infinity hood i love it. It has the largest viewing area on any auto darkening lense. Thanks for watching man.
Nyce1 only when Iam doing custom stainless exhaust I would do fusion but good video
I fused a outside corner joint on 0.063 aluminum it's plenty strong to build light fixture boxes.
Yeah for art stuff and things as such by all means thats works. Thanks for watching
Well from the video, they make it seems as though if you fuse aluminum it will fall apart. Because it's not applicable many would assume it's impossible. It's not, I can fuse a outside corner and then fold it over and still hold without breaking.
Your weld looks far more realistic than say Pacific Arc Tig Weld channel. His weld just always looks shiny and stuff.
I'm practicing on some 1mm and 1.5mm stainless and I found as soon as I introduce filler wire into the equation, all hell breaks loose. I'm thinking something that thin is going to be fusion only, because by the time I can get enough of a puddle on those metal to have filler wire, the metal is already cooked.
It's much less of a problem on 3mm or thicker metal though.
Anytime I fabricate any Stainless Steel architectural parts that are going to be polished, then sit and look pretty, I almost always fuse, unless I’ve got gaps. Not using filler makes polishing much easier. I also fuse when welding Stainless sinks, countertops, etc. this insures there will be no contaminates introduced into the weld pool from the filler wire.
Absolutely man thats whats so nice about stainless is knowing all that kind of information and taking that into consideration when fabricating thing can make the job alot easier. Thanks for watching
Thats wild cause with steel and just a tack weld i cant move it with even a a beating from a bfh that tensile strength is wild some times
but why autogenous/fusion welding instead of using filler wire ? what’s the benefit?
Few questions.
Please answer in serial order
1. For welding 0.6 mm stainless steel 304 which welding method should I prefer mig or tig
2. If I use tig welding on 0.6 mm SS 304 should I use filler rod
3.which welding method is expensive mig or tig
4 while browsing i found people generally prefer mig more than tig,why
5 which welding method is more expensive mig or tig
6 can I use carbon dioxide instead of argon for SS welding
7 how often we need to change tig welding tip
In my personal opinion and preference although im not well experienced.
1. I prefer TIG
2. Yes (personal preference)
3. TIG (in my country) bec argon and any TIG consumable much expensive
4. MIG and also FCAW was much easier compared to TIG
5. TIG (same as reason no 3)
6. Yes, but if you use pure CO² the material will lose resist corrosion ability so better use mix between Argon + CO² (use CO² less than 5%)
7. Personal preference, if i want to change it then i just change it lol.
I use a jewelry tip with gas to fuse weld cones for sheet metal expansion chambers. Use the outer part of the flame to preheat the metal, them use the inner flame tip to walk the flame along the joint. Keep the flame almost tangent to the curve of metal and just move the flame along and it will fuse together almost seamlessly. Tig is to slow for what I do.
Thats crazy ive seen it and it can get pretty intricate, ive never done it. Jewelry woukd be pretty cool to do i bet once get into it and have all tools to do so.
Make sure the metal butts up tight, no gaps.
Sounds interesting. I'm trying to understand what you're explaining, but I don't really understand. I looked to see if I can find some RUclips videos of this, and can't find what you're describing. Could you point me to a video that shows your method? Thanks!
What about regular old steel, btw? And aren't spot welds autogenous?
On that I would not use that. I feel like it's causing way too much undercut. It's good for tacking, on some bigger stuff I like to tack it that way and then recheck measures etc. It comes down kinda easy. If everything is OK I reinforce the tacks with filler wire (they really like to pop when welding) and weld it. Good when You are fitting frames or something like that to be MAG welded. When stuff must be gas tight or something I'll maybe fuse it because I feel like I am more sure about the material bonded together without any holes etc. But still I'll do a cap with filler afterwards. But it's all about the material used, thickness, fitup. I feel like thin sheet stainless or thin stainless tubing is best for this application (only with perfect fitup tho).
Spot welding can be considered autogenous since no filler is used. But... that's it. It's whole different process.
Hope that does cover it. Maybe someone will add something down there or maybe even coreect me a little. Have a nice day.
Well, it depends. I do it at times. What it it being used for, and how thick is it?
Thank you for the informative reply@@JV-hm4ik; it covers our question well.
We've had a MIG for a while, but have added a YW TIG machine recently. It's got a "spot" more that may work for tacking, so we're considering tacking w/TIG and, for thicker steel work, MIG to weld-up. More process options give us more flexibility, but we've got more to learn to use it best.
Spot mode, Cold tack mode or whatever You call it is good for thin stainless tubes and sheets. It would sure work on some sheets of good old steel too, but I've never tried that to be honest. I'm also reinforcing all those tacks straight before welding itself.
We just had a job where we did some frames for machines and 2 of us were tacking the whole frames up with TIG (just small "stiches" about 10mm long with some filler wire) and the third one was MAG welding them. We did save a lot of time because she could focus only on welding it and all the setting up parts and measuring and tacking was on us.
Welding up a stainless hardtail chopper frame😎
Love a nice stainless hardtail chopper frame.
I know somebody’s favorite word
Is it "applicable"? LOL....
This comment is only applicable to this video.
@@theroastbeefking We're just giving him a hard time. Nothin but love. I very much enjoyed the video.
Yes sounds like there is a director behind the camera. They should leave him alone and let him weld. He has skill.
On reg carbon steel ?
Kid can weld, but boy does he repeat!
Do it for dale!! 3
Does fuse welding destroy tungsten rod of the torch? Thanks.
You didn’t perform any prep on the aluminum you were doing. Might help
ALL arc welding is fusion welding. I occasionally see this callout on drawings and it drives me nuts.
what is meant by "sugaring" new term for me
The chromium has a high activity at welding temperature. Back side of a zero gap weld will oxidize, making a mess looking like burnt sugar, black and bubbly. This make a joint ugly, weak and prone to corrosion. Open root welds get shielding through the gap but still can sugar.
Back purge with argon or other inert gas is used after tack weld. The tacks are only partial thickness, easier to do with stainless as it is a poor thermal conductor.
Solar Flux Type B can be applied to the ID if the pipe/tube can be cleaned. Most are high purity and must be back purged. One example of good use is exhaust tube. Or turbo headers, run no gap root with Solar B, then fill with water for fill/cap. This also cleans the flux off the inside. Just don't seal it with water inside and make sure the weld area is under water. Sure sinks the heat away so welds stay nice looking.
@@keithjurena9319 Thank you so much
Up-speak is when every statement is ended with higher voice pitch as if you are asking a question. Don't do it
also not ideal for dissimilar materials
Someday Tig welders will evolve a third arm
Freak: did someone say high freak tig?
I tack without filler that’s it lol
You need to be more precise step by step like gap or no gap on stainless pipe
Simple answer WHEN THE WPS STATES period 🤨
Thanks captain
Never weld for yourself?
6061 aluminum is "unweldable" which is why tacking it is awful ... the filler metal is usually 4000 series. I would never fusion weld aluminum, not even for tacking. Hold the part with some sort of jig, or use a spool gun instead.
When i do this to make a tack it hadly penetrates i make it to where it just stick long enough for me to grab a piece of wire and tack it off
6061 is difficult to weld without 4000 series filler as it lacks hot ductility. It is also sluggish, the silicon in 4043 adds fluidity.
