Strictly control the interlayer temperature, with small current, fast welding speed to reduce the welding pool overheating.
Stainless steel has a good welding specific, but because of the specificity of its internal composition, when welding, such as poor process control, easy to intergranular corrosion, stress corrosion cracking, thermal cracking, brittle tendency, etc., these phenomena are prone to stainless steel body loss of corrosion resistance, pipeline strength and plasticity reduction, physical properties deterioration, the need to pay attention to the welding, strength of advantageous enterprises more than the use of pipeline automatic welding equipment to deal with This problem. Stainless steel pipe welding, first of all, should be the correct choice of welding materials, the use of low carbon content and the appropriate amount of Cr, Mo, Si and other elements of the welding consumables, before welding, do a good job of cleaning the pipe fittings, welding process using the back of the gas protection. Strictly control the interlayer temperature, with small current, fast welding speed to reduce the welding pool overheating.
