Architects and engineers are designing structures with new and innovative shapes. To meet these ever-changing requirements, manufacturers may turn to solid-state, high-frequency electric resistance welding (HF ERW) to produce engineered structural sections at high speeds with unlimited beam profiles, better structural performance, and with lighter weights.

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.

Like many companies, Ultra Machine and Fabrication Inc., Shelby, N.C., a fabricator of armored military vehicles, believed the welders should clean up their own weldments for spatter, slag, and other discontinuities. But when welders were spending less and less time under the hood, Ultra re-evaluated this philosophy and, as a result, implemented a separate postweld cleaning team.

A unique method of metal transfer allows gas metal arc welding to tackle thin-gauge and cosmetically sensitive workpieces.
Some welders swear that stainless steel warps if you just look at it wrong. This is an exaggeration, but it does reflect the metal's low rate of thermal conductivity, which causes the input heat to remain localized; localized heating and cooling promotes distortion. Adding more heat doesn't...
