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...

Preventing weld defects through proper consumables care

March 10, 2014


SMAW electrodes are magnets for moisture if they aren’t properly stored, maintained, or handled. Moisture—hydrogen—can ultimately lead to cracks when deposited into the weld puddle. You can minimize moisture pickup with proper electrode storage and handling procedures to ensure that consumables operate at optimal levels.
