Surface treatment of stainless steel BA pipe after welding
- Aug 31, 2018 -

Full automatic pulsed argon arc welding technology is used in pipeline welding. During the welding process, argon gas is filled inside the pipeline and in the argon gas pipeline on the welding machine, so as to protect the pipeline from oxidation in the welding process. Argon protection can effectively reduce the oxidation of the inner and outer surfaces of the weld.


Corrosion resistance is better because a dense and uniform oxide film can be formed on the surface of the welded piece with fine roughness to protect the internal metal from oxidation and corrosion. However, this method requires in a relatively dry environment, and mechanical grinding polishing of a variety of polishing wafers, using this method, polishing wafer selection is more important, there are straight lines, nylon lines, snowflakes and other options.


Stainless steel pipe is a kind of economical cross-section steel, is a tense product in the iron and steel industry, usually accounting for 8% to 16% of the total steel, it is widely used in the economy of the people. Because the steel pipe has hollow section, it is the most suitable to assist the liquid, gas and solid transportation pipeline. At the same time, compared with round steel of the same weight, the steel pipe has large section coefficient, high bending and torsional strength, so it has become a variety of rigid and structural layout of the tension material.
