That's thin stainless, and I know how hard it is to avoid full penetration of thin stock and the resulting granulation or sugaring. For the part where you aren't able to back purge it looks like an ideal application for Solar Flux or equivalent. It's a powder you mix with alcohol to form a paste and brush on the back side of the weld area and let dry. I've found it works very well. Leaves a very hard glassy residue wherever it melts. The residue that doesn't easily brush off is smooth and can usually be left in place, as it's stuck on very firmly. With all that said, you're a much more skilled welder than I am, Jeff.
Thank you man. When i do that i was using a thicker wire and weaving it not trying to stay to long on the base material and stay more on the wire and keep it moving to prevent the sugar. But i have used solar flux when id did process work on long runs for utility piping on the roof and such, its cool stuff. Thanks for watching and reaching out
It doesnt make so much of a difference when they all collect together other than the actual runner lengths. Or they do whats called a tri-y collect when two and two collect then those two collect into one. That also makes a difference
Rather than grabbing a 1/8th filler why doesn't he just feed more rod in the puddle? Also welding is the easy part, next time show us how to make the collector
Wow, his hand is shaking so much. And his stand off distance is way too high. He's not comfortable welding thin-walled stainless tubing and it just looks "chunky" and like he's always "chasing the puddle" to fill. Not nice work. And he keeps talk about "sugaring" the inside weld, and how using a larger filler wire fixes it. I can't imagine why anyone one would weld thin walled stainless without a a back purge. Your ID weld will always have "sugaring" without a back purge. This video is all about bad fit up, no back purge and shaking hands.
You can use a simple flux. sodium tetraborate and boric acid grind into powder. Add isopropyl or ethyl alcohol to the flux powder to get a viscosity like sour cream. Spread a thick flux from the inside of the pipes to be welded, wait 15-20 minutes and weld by tig.
He was clearly back purging at 7:40 or so, you can see the double regulator/green hose in the back of the exhaust and taped-off exhaust ports on the header flange . Not sure why he didn't back purge on the earlier welds as well. Maybe it was done on a different day and the back purge setup wasn't available. Can't really comment on the rest of his technique, he welds better than I can for what its worth!
He clearly isn't a production welder. He probably isn't trained in that industry. This is probably his lane, and their isn't anything wrong with that, so don't hate too hard.
I don’t think you really need a purge for stuff like this. I mean you can just turn your heat down like you should for stainless. It’s not like this is food processing equipment. I’d also do as much fuse welding with low heat as possible. If it’s just a seal weld then no need for filler rod if you have a tight fit up.

Solar Flux is definitely something to keep in the tool box! Saved my butt a few times
Nice video! Even more stoked that a gmc syclone grill is chillin in the background
Thanks man im about to get it going again just rebuilt the engine for it thats why the grills out, to ensure didnt break it removing the engine
Nice Work , I would of like to see that whole header project from the start .
Would like to know more about the purging setup.
we have some awesome videos on this in the weld app
That's a beautiful professional job.
Thank you for watching
Very nice, did you position the four tubes according to the firing order for a circular exhaust flow?

Very nice feed hand and everything else.
2:10 love those arc shots - nice color filter too
Yeah we got some good arc shots on this one thanks for watching.
Beautiful work.
Thank you
well done Jeff Ray.......cheers from Orlando, Paulie
Thank you Paul Brown
@@SuperformanceFab you looking great for an Olde Timer Jeff....cheers my friend....Paulie
Fantastic level of skill and workmanship thanks for sharing your experience and time with us
Excellent video with great arc shots, If you can share the info, how long did the whole process take start to finish?
Nice work, Jeff! Did you use the large cup mainly to get those (beautiful) arc shots? If so, what size cup would you have used if you weren't filming?
Gas coverage.
Hey…….let’s get at it !
Quick question how do you tell if you have good pen on thin tube
The inside will as good if not almost best than the outside if you have good purge on it and good enough penetration.
That took some skill to pull this off.
Love your technique, you make this look so easy that internet keyboard welder virtuosos jumps in with suggestions lol.
Slick!
Why did You ask "What's up guys" at the start? Do You really need to know?🤩
Its what i say to get me focused on my intro it works for me idk hahha
@@SuperformanceFab 🤩
looks like the heat input is too high, but the finished weld has almost no discolouration? how?
That’s right. Heat input very high
What is up with tig weld a header? You can same with mig! If you are a good welder. Heat control
excelente trabajo saludos
Is a 429 the stock motor for that Bronco? That's a lot of ponies there.
I dont believe so but it has rods pistons crank and some head work it sounded awesome when i was done with it.
Class mate
Looks like your tires will hit those headers.
They actually clear really well he has yet to have them even come close into close proximity to each other thanks for watching
damn good welder the kid is

It came with the kit.
