X60 automatic welding pipeline (including submerged arc surfacing and electroslag surfacing, etc.) is a method of welding by burning the arc under the flux layer.Its inherent advantages such as stable welding quality, high welding productivity, no arc light and little soot make it the main welding method in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beam and column.In recent years, although there are many new welding methods with high efficiency and high quality, the application field of submerged arc welding is still unaffected.Submerged arc welding accounts for about 10 percent of the weight of deposited metal in various welding methods, and has not changed much over the years.
When the X60 automatic welding pipeline welding wire is determined (usually depends on the type of steel to be welded), the supporting flux becomes the key material, which directly affects the mechanical properties of weld metal (especially plasticity and low temperature toughness), crack resistance, incidence of welding defects and welding productivity.The weight ratio of welding wire and flux is welding wire: flux =1.1~1.6, depending on the type of welding joint, type of flux used, and welding specification parameters.Compared with melting flux, the amount of sintered flux is less, about 20% less.
