Differences Between Electric Resistance Welding and

High-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW is the abbreviation of electric fusion welding. Differences Between SAW and ERW Pipe Winsteel GroupAs the name suggests, SSAW has a spiral weld seam. And LSAW has a longitudinal weld seam. ERW pipe means Electric Resistance Welded pipe. Second Differences Between SAW and ERW Pipe We Will See It From The Weld Seam. The surface quality is very important for pipes. Though both SAW and ERW pipes all have a weld seam.
