摘要
Abstract
To prevent from the corrosion of the medium,hastelloy C4 material belonging nickel -based corrosion resistant alloy of Ni-Cr-Mo type with single-phase austenite was selected and adapt as the bottom of residual liquid tanks.With TIG welding method and ERNiCrMo -7 welding filler,the tech-niques were adapt such as groove design,pre-weld cleaning,temperature control between channels and lower welding heat.welding procedure qualification test has been passed and the metallographic micro-structures analysis of welded joints were conducted.The results show that the welding process can ensure the mechanical properties and corrosion resistance of welded joints.关键词
