Not the answer your looking for but when I did a few 5ft welds, the first one looked like a banana. TQ advised doing segments and then filling in between the segments. Took me a while but it did work. And that stuff was 1/8".
Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life
Stitch welding is really the only way to go and burning too hot from what I have watched makes it warp real fast… But Frank would be a good one to ask on this…
If you can't fix it by sheer force or cursing......then it can't be fixed.....
Miller 175 welder using 75/25 mix and .030 SS wire. I tried thinner wire and as many combos of feed speed and voltage. I even had a more experienced welder try it out and he was having problems as well. I've come to find out that not many folks have ever welded stainless. If I remember correctly it's 400 series stainless. The only wire I could find was 300 series, if it makes a difference. I also have a roll of regular steel wire but haven't tried it.
I read about changing the gas to 95/5 or tri mix but can't find it around here, at least for the amount I need.
If it's tourist season, how come I can't shoot 'em?
Thus lies youre problem. Stainless is a B*tch to weld from what i remember. i havent welded anything stainless since my days as an apprentice but if memory serves because its not pure Steel and its got Chromium and Nickle in their it has a much higher coefficent of expansion. like almost double.
Only ways to weld it is with speed or you're goign to have to be rediculously parient stitch welding.
doing a bit of research on this myself i also came across a wire guide, if youre steel is 400* most likely 410 then youre going to need 410/309L wire.
No one around here has that mix, at least in the sized tank that I have. Couldn't even lease one.
I think I'm going to line the inside with steel and just use the stainless for the outer skin. I had better luck welding to the 1/8" square tubing that I used for the frames and all of the outer skins just get welded to the frames. I'll offer some of the leftover stainless to my metal supplier in exchange for a break in the price.
Thanks!
