Read moreDesigning with HSS: How the ERW Manufacturing Process Works
Electric resistance welding (ERW) is the primary manufacturing process used to produce hollow structural sections (HSS) in North America. Each of the seven stages in an ERW tube mill, from coil entry through quality inspection, directly determines the dimensional accuracy, weld integrity, and mechanical properties of the finished section. Knowing w...
