Consumables Corner: Causes of centerline cracking in FCAW root passes

January 20, 2015

By: , ,

Q: We are a bridge and structural steel manufacturing shop that uses a mixture of common base materials such as A36, A572, and A992. Recently we’ve been experiencing sporadic centerline cracks in the root passes of fabricated I-beams that we weld with flux-cored arc welding (FCAW). Oddly enough,...

Consumables Corner: Eliminating porosity on galvanized steel

August 28, 2014

By: , ,

Q: Our company manufactures storage rack systems made from mild steel and galvanized tubing. A majority of our parts are fixture-welded on a robot using 0.045-in.-diameter ER70S-6 wire with 90 percent argon/10 percent CO2 shielding gas. We have experienced problems with weld appearance quality and...

Consumables Corner: Simple steps to avoid cracking

June 25, 2014

By:

Q: When welding a thick section of a forged 4130 ring to a thinner A36 plate in a T-joint configuration, we experience longitudinal cracking issues that originate from the ends of the welds. The required fillet size is ½ inch. It is skip-welded 12 in. on 18-in. center-to-center spacing. The...

Consumables Corner: Eliminating porosity in submerged-arc welding

June 19, 2014

By: , ,

Q: Our shop manufactures bridge and structural steel components. Most of the material is A36 or A572 and welded with E70X-X class electrodes using FCAW with 75 percent Ar/25 percent CO2 shielding gas (bottle-supplied) and SAW. We're having issues with porosity in our SAW process. We find that once...
