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...
