Abstract
In order to research the weldability of Q345R/316L clad plate with (13+3) mm thickness and the deformation control of its welded joint, three welding electrodes were selected to carry out the welding procedure optimization. The study found that the deformation of welded plate with asymmetrical X-groove was less than plate with symmetrical X-groove after welding. The mechanical performance of welded joint was analyzed by using tensile test, impact test, bending test, hardness test and shear test. Intergranular corrosion test was adopted to evaluate the intercrystalline corrosion resistance of the stainless steel welding. The results showed that the mechanical property and intergranular corrosion resistance meet the requirements of the relevant technical standards and demands of the users.关键词
