TIG welding cold rolled steel 3"x3" x1/4" using er309L and E70s-6 filler metal.
12 outside joints provides plenty of welds to experiment using different size filler metals and pulse settings too.
There is also a second video of filling in the corners using silicon bronze.
Controlling the puddle, getting adequate penetration, avoiding undercut, preventing arc blow, and complying with AWS D1.1 acceptance criteria are all important.
Some welders are being required to test using 5/32" 7018 electrodes instead of smaller diameter electrodes like 1/8". 130 amps is at the...
