I suspect he is out in his shop satisfactorily stacking iron for his customers/employeer, as depicted.

lol. Whatever did we do before WPS and their attendant cubicle dwellers?

If you're soooo interested, why don't you go find out for yourself? You seem to have the time on your hands.

"And on the eighth day he created... Dilbert."

"And among the welders there arose a great cry, for the riddle of steel was but a jelly stained paper slide rule in his shirt pocket."

I've done it before, I know what happens, read my other posts in this thread. My largest mig machine is just on the border of spray capable, marginal at that. The guy is claiming something quite out of the ordinary. I'm just curious, especially since he said it wouldn't be an issue.

(me too - not calling him out - just curious to the cross section test)

I'm willing to wager that if you have a machine that has the balls to run spray transfer, you will probably be able to pass a bend test with straight argon.


However, most home shop welders don't have the voltage to push spray. To recommend straight argon to a home shop is not good advise.

Just because a weld passes a bend test doesn't mean it is a nuclear weld. The AWS exists for a reason. If they don't qualify a weld, it usually has some apparent flaw in the process. There isn't a qualified MIG weld on steel using straight argon because of the lack of penetration. Period. Some production monkey can say whatever he feels, but at the end of the day it comes down to the necessity to follow proven processes to prevent failure.

I don't know why anyone would even want to mig with straight argon since it's more expensive than c25.

I agree 100%. I was just saying that because all he was trying to prove was that it would pass a test, not be an appropriate procedure. Just because someone's gotten away with something doesn't make it correct.
