I will probably be testing for 3G and 4G Mig certs in the near future.
I've been welding for many years, but the majority of the work in our shop is 16ga. tube, so the idea of 3/8" plate is a little outside of my comfort zone.
I was looking at the following website, which seems quite helpful, but I cannot figure out what the guy is talking about when he gets to the section about preparing the coupons for testing...
Also, does anyone have experience with the Hobart program in Troy, Ohio? This is the closest AWS facility to us.
Thank you for your help.
