5 tips for welding stainless steel tube and pipe

The filler metal used for stainless steel tube and pipe welding should enhance the weld properties and meet the application requirements. Look for filler metals with an "L" designation, such as ER308L, because these provide a lower maximum carbon content, which helps retain corrosion resistance in low-carbon stainless alloys.

Pipeline Equities - A Brief History of Steel Pipe

Welded pipe is formed by rolling steel strips through a series of grooved rollers that mold the material into a circular shape. Next, the unwedded pipe passes by welding electrodes. These devices seal the two ends of the pipe together. This process in the United States was opened in 1832 in Philadelphia.
