Submerged arc welding machine is a welding machine that uses arc to burn under the flux layer. Its inherent welding quality is stable, welding productivity is high, no arc and no dust and so on, so that it becomes the main welding machine in the production of pressure vessel, pipe section, box type beam and column steel structure. In recent years, although there have been many kinds of efficient, high-quality new welding machines, but submerged arc welding machine applications are still not affected.
Submerged arc welding machine is divided into two categories: automatic welding machine and semi-automatic welding machine. Semi-automatic submerged arc welding machine is composed of welding car and submerged arc welding machine, welding car can walk around, speed adjustable. Automatic submerged arc welding machine is composed of submerged arc welding machine and auxiliary equipment, can achieve automatic welding.
