spot welding aluminum ?
I spot welded some scrap .025 thick 2024-T3 aluminum I had into a box to hold file folders. The spot welds seem okay but I had some trouble with the steel sheet I was using sticking to the aluminum. Is there any trick to avoid the sticking ? Thanks ~ John Buchtenkirch

Maybe a bit of oil.

I had heard that stainless steel was used, don’t know about sticking.
I did try it a number of years ago don’t remember it sticking. Steve

I think thin stainless would do the trick. From memory, Jimmy Hervatin posted a short video on his Instagram showing just that.

Sorry guys, I just tried the SS on both of my spot welders and it’s still sticking just the same as steel. Thanks anyway, it was worth a try. ~ John Buchtenkirch

Maybe reduce the time, or current?

all the aluminium i have spot welded it was using steel between the tips, try using thin copper between the steel and aluminium

BRAVO………. that worked perfectly ! You only really need to put the copper then steel on one side (to raise the resistance) and it seems to work just fine. THANKS Neil ~ John Buchtenkirch
