GMAW for beginners

January 20, 2017 | By Adam Urbano, Rhonda Zatezalo

Even though GMAW is relatively simple process to execute in comparison to other welding processes, there are a lot of moving parts that will either make or break your weld. New welders have a lot to consider, including understanding the base metal, the type of weld necessary, how to set up the machine, and how the best to lay the bead. Knowing which is best for the application is often part of the challenge.

Consumables Corner: Preventing porosity on weldable primer-coated joints

September 23, 2016 | By Nino Mascalco, Rob Koltz, Steve Sigler

Q: A majority of our welding is done on 1/4 to 5/8-in.-thick carbon steel that has a weldable primer. Most of the welding is done on basic partial joint penetration (PJP) T-joints without any joint prep. We use an E70T-1 0.052-in.-dia. flux-core wire with a 75 percent Ar/25 percent CO2 shielding...
