HSS sections are produced as cold-formed members using different methods, but one common feature resulting from HSS production is a continuous longitudinal weld, or the weld seam. This weld seam is treated differently depending on the desired AESS category for the exposed steel. Below is a summary of weld seam requirements in HSS members

Introduction to Welded Pipe Manufacturing - The Process
Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessDifference between Seamless and Welded Tube & Pipe Welded tube start from stainless steel strip and coil that is passed through grooved rollers till the shape is formed and the free edges are properly shaped for welding, cold forming is performed step by step from flat strip into a round profile, the edges are welded together as they approach the welding rolls.

Stainless Steel Tubing:Seamless Vs. Welded - HandyTube One way to produce stainless steel welded tubes to take a strip roll-formed and joined with a longitudinal seam, however the weld area remains dimensionally inconsistent with the strip and causes areas of stress concentration, particularly for tubes that are subject to high internal pressure.
The api 5l longitudinal seam welded steel pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements.
