A welded stainless steel tube is produced through roll forming strips or sheets of stainless
steel into a tube shape and then welding the seam longitudinally. Welded tubing can be accomplished
either by hot forming and cold forming processes. Of the two, cold forming results in smoother
finishes and tighter tolerances.Welded tubing is produced by rolling strips of stainless steel into
a tube and then welding along its full length. After welding, the weld seam, or bead, can be refined
by cold rolling and forging methods or left as is.
