the electric arc welding process uses an electric arc to generate heat to melt the parent material and the filler material (electrode) to form a molten weld pool in the joint. the electric arc welding method is preferred over other methods due to its affordability. the most commonly used fastening methods for joining steel members [ ]
many structural steel fabricators are loyal to shielded metal arc welding (smaw). but technology advancements in the wire feed process known as flux cored arc welding (fcaw), paired with an increasingly competitive market, have changed the landscape of structural steel environments, and by extension the opinions of the most loyal smaw users.
jul 13, 2020 structural welding involves creating a variety of welds with different component materials to create, fabricate, and erect welded structures. structural welding has its own set of codes, blueprints, and types of weld joints. structural welders require a specific set of skills involving balanced measurements and precision to do an effective
