Title: Study on the welding process and parameters of 253MA imported material pipe fittings
Abstract: The imported material 253MA is a high grade high temperature and corrosion resistance stainless steel.The main features and purpose of this material are pointed out in this paper.In view of this material pipe fitting,a set of automatic cutting and welding equipment is designed.The cutting and welding method,equipments,and a kind of the welding wire and its diameter are selected.Some appropriate welding parameters and welding process are decided by using welding test method.Structure and mechanical properties measurement of weld are completed by means of 253MA material sample.The experiment results show that welding joint's quality is good and meets the quality requests.The welding problem of the imported material 253MA pipe fitting is successfully solved.These research results make contributuions to weld other 253MA material.
