help with mig test welding

by Craig R
(Greene, Iowa)

I have had a mig welding test before, but it's been several years and standards have changed along with different weld shops have different tests. The weld test I am taking will do a cut through the piece to see if there is any porosity. Do you have any advice on how to do the test? I hear many passes have to be made to do some kind of fill in.


for a test like this, make sure to clean all the islands of silicon on each pass...

keep the arc on the leading edge of the puddle.

weld hot enough to see the leading edge biting in.
but not so hot that you cant control the puddle

not knowing the joint type or position, i really cant weigh in much more.
