Welding refers to a wide variety of processes in which metals are joined by fusion. The metal at the interface of two or more parts is melted or fused by application of intense, localised heat. A ...

In the tungsten inert gas (TIG) welding process, an electric arc is struck between a refractory electrode made of tungsten and the work piece, while a shroud of inert gas, usually argon, shields the ...

Arc welding remains a cornerstone of modern fabrication, enabling the joining of metals through an electric arc that generates intense localised heat. Recent advances have focused on refined control ...

Residual stresses arise in welded assemblies as a consequence of non-uniform heating and cooling during the welding cycle. Rapid thermal transients induce localised expansion and contraction, leaving ...

A senior-level rundown of how onshore/offshore line pipe joints are welded into a continuous, code-compliant pipeline—what it is, how it’s executed on the right-of-way or lay vessel, and how to ...
