Comparative study on shrinkage deformation of 18Ni steel girth weld by TIG welding and electron beam welding
TIG(inert gas tungsten)welding and electron beam welding were used to weld the circular joint of 18Ni high-strength steel cylinder.The shrinkage deformation and mechanical property of 18Ni steel circular joints by different welding methods were studied.The microstructure of TIG and electron beam welded joint was studied by metallographic observation.The tensile tests showed that the tensile strength of electron beam welded joint was higher than that of TIG welded joint.
