Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method of burning arc welding under the solder layer. The common welding equipment includes Gouging Torch K3,Gas Cutting Machine.Its inherent welding quality is stable, welding productivity is high, no arc and little dust, etc., making it a pressure vessel, pipe manufacturing, box beam and other important steel production in the main welding method. In recent years, although there have been many kinds of efficient, high quality new welding methods, but the application of submerged arc welding is still not affected. Submerged arc welding accounts for about 10% from the point of view of the weight of deposited metal of various welding methods, and has not changed much over the years.
