Tig welding tips, questions, equipment, applications, instructions, techniques, tig welding machines, troubleshooting tig welding process
I would grind out the crack almost all the way through. Then weld one pass with filler. This first pass will likely be full of porosity and flakes of junk. But you grind out some of that nastyness and do the same thing over again. After one or two or three times most of the oxidation and contaminates will be gone. Then you have a solid base that will allow you to build on till you fill it out.
I have more questions than answers

...Or, you grind it open, preheat with Propane to purge impurities, then clean with Acetone and Stainless brush. Then weld it up. Same process I've used heaps of times welding Jon boats impregnated with alkaline heavy water and mud. Its not fun, its not easy, but its very doable. I have never used He on these jobs, just straight Ar, though I have something coming up I might just whack it with...
Thanks for insight, glad that I didn`t agree back then to use mig (Lincoln magnum I guess) that boss showed me and weld aluminium. Only thing I knew back then, that for AL welding you need round rollers and special liner. I would make a great hole in that tipper.

Hi guys I'm new to the forum but not new to welding. I have been welding for a couple aerospace companies in Southern California. Anyways yes you can weld aluminum in DCEN with 100 percent helium high purity grade not balloon grade. If you know how to weld it it comes out just as nice as ac or even nicer, especially if it is really thick aluminum like 3/8 or thicker.

Welcome to the forum, is this process used at your facility? Got any photos you can post?Gon-Welding951 wrote:Hi guys I'm new to the forum but not new to welding.

Pretty darn cool Gon-Welding951
Since the amperage is dramatically less with DCEN on aluminum, mind telling what amps (approximately) those were welded at for reference?

Thank you guys. Usually on 1/4- 3/8 around 205 amps anything thicker like 1/2- 2" 210- 250 amps. My favorite set up is a 3/32 red band tungsten #7 gas lens and 40- 60 cfh on helium.
