Product Description:
Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) ,SSAW STEEL PIPEis an important welding method. Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little smoke make it the main welding method in the manufacture of pressure vessel, pipe section, box beam and column and other important steel structures. In recent years, although many new welding methods with high efficiency and high quality have appeared successively, the application field of submerged arc welding has not been affected. From the perspective of the share of the weight of the deposited metal in various fusion welding methods, submerged arc welding accounts for about 10%, and it has not changed much over the years.
