SSAW spiral submerged arc welding pipe
Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is an important welding method. Its inherent advantages include stable welding quality, high welding productivity, no arc light and little smoke, etc.In recent years, although many efficient and high-quality new welding methods have appeared successively, the application field of submerged arc welding is still unaffected.From the perspective of the weight of deposited metal in various welding methods, submerged arc welding accounts for about 10%, and has not changed much over the years.
When the wire is determined (usually depending on the type of steel being welded), the supporting flux becomes the key material, which directly affects the weld metal's mechanical properties (especially plasticity and low temperature toughness), crack resistance, occurrence of weld defects and welding productivity.The weight ratio of wire to flux: flux =1.1 ~ 1.6, depending on the type of welding joint, the type of flux used, welding specification parameters.Compared with smelting flux, sintering flux is more economical, about 20% less can be used.
