Abstract
By comparing the macroscopic morphology,micromorphology,and mechanical properties of the welded joints un-der various welding parameters,the welded joints with better comprehensive performance were obtained at the welding speed of 13 mm/s and the welding power of 600 W.In this paper,TA15 titanium alloy and T2 copper with a thickness of 1 mm were welded by laser welding.After choosing the microstructure morphology with the typical morphology analysis,the phase com-position of the weld was examined by integrating the findings of the XRD and EDS tests.It was found that CuTi2 compound and the Cu2Ti+Cu4Ti eutectic structure made up the majority of the weld.When welding copper/titanium dissimilar metals with a laser,there will be holes,cracks,and other welding flaws in the weld,which significantly reduces the mechanical quali-ties of the welded connection.After analysis,it was determined that the tensile fracture of the welded joint was a common brittle cleavage fracture.The microhardness test findings of the welded joint indicate that the weld is mostly made up of copper-titanium compounds,and the heat-affected zone on the copper side clearly exhibits a joint softening phenomenon.关键词
