I've read that its not possible to get a good enough join if you try to stick weld SS and Copper. Is that 100% correct?
I've got VERY little welding experience. I welded a trike frame together rather poorly but they did hold together. Lots of overkill on the welding and I think I've laid maybe one barely respectable bead ever that was only a little over an inch long.
I snagged a box of 620-308L electrodes last night because I have a couple projects dealing with stainless and these were heavily discount. I grabbed a couple scrap pieces of stainless and just welded an inch. Then I grabbed a piece of copper and welded it to a piece of stainless. That weld was basically a 1" tack/bead. The copper receded a bit so I backed the amps off a bit and continued testing it. The weld wasn't pretty but I was unable to rip it apart. I final ripped the copper off the stainless by over bending the copper over and over.
So I ask again, is 100% true that you can't get a strong enough join stick welding copper to stainless?
I should mention the the stainless was 304 1/16" thick and the copper was a cut open and flattened 3/4" copper pipe. The stainless looked fine afterwards as did the copper but the copper was a little red on the back side.
