Article Preview

Abstract:

This paper studies the properties of 1Cr18Ni9Ti/Q235 compound steel, it mainly introduces TIG and SMAW comprehensive welding technique of 1Cr18Ni9Ti/Q235 compound steel. This process adopts stepped groove, welding material and technics are chosen according to base layer and compound layer, the boundary of both base and compound layer are welded respectively, welding sequence is reasonably arranged. Experiments proves that corrosion resistance and compactness of the welding joint are good, welding joint strength is high, welding quality meets operating requirement well.
