Heat input. Sorry Jodie :)

admin

1/8 lap joints that are 3 1/4 long. 1 ran at 160 amps floored with less overall heat input and the other ran at 90 amps floored that took much longer and more overall heat input. I should have put the heat gun on them both right after but just now thought of that lol.the one welded  At 90 amps it started to flow good the last 1/4 of the piece. Ran a red 3/32 tungsten with #5 cup at 10 cfh and 1/16 70s2. I plan on doing another one maybe at 180 amps.

Reply:the one on the far left was welded at 80 amps. And I tried welding another at 180 amps. I was amazed how big the puddle was and was kinda whatching it instead of moving and adding filler. The heat zone was a tad bigger on the one welded at 180 over the one welded at 160. The heat gun read about half the temp as the one welded at 180 then the one at 80 amps.
Reply:YUP that's what I was taught crank the amps and move faster  put less heat into the work/

Reply:Well?I certainly am at AWE!I would have not thought that the HAZ would have been like that.It does make sense that you would have to heat more material WAITING for the Welding area to reach bonding temps at lower amps.Thank You!
