This subject comes up every once in awhile, and I've never seen it done. So I thought I'd give it a try. Took four hundred forevers to get the filler rod from weldingsupply.com! Back ordered, and all.
Started on some 1/8" x 1" flatbar. Did some corner joints, lap joint, and a fillet weld. Used 3/32-inch Ceriated tungsten, at 150-amps, with 100 % pure argon. Took a little bit to get enough heat built up to form a puddle. But didn't take to long until I was backing out of the pedal. In some ways it reminds me of welding aluminum, except the puddle looks dirty. I used a brand new steel wire wheel on a 4-inch hand grinder to clean the base metal before welding. After welding I tried a new Scotch-Brite pad, but wasn't very successful, so I used a new stainless steel hand brush. I learned if I let everything cool to the touch, the black cleaned off easier. Soon as I lifted my hood after welding, every piece was glowing red hot!
I tried a couple welds on 1/4-inch material, it took all 300-amps to weld the 1/4-inch!
Kind of fun to do, learned something new today!
