Abstract

Abstract

A two-pass laser welding test was carried out using TC4 titanium alloy and 316L stainless steel as the base material and pure vanadium as the interlayer material. The influence of welding speed and beam offset on weld formation, microstructure, and mechanical properties were studied and analyzed. The results show that the vanadium interlayer on the side of titanium alloy can be melted to a certain extent. Still, all near the interface are the solid solution, and the mechanical properties of the joint are less affected. On the side of stainless steel, the vanadium interlayer is brazed with the stainless steel. Vanadium dissolves and diffuses to some extent, forming a diffusion layer. With the increase of beam offset on the steel side, the thickness of the V/Fe interface diffusion layer decreases. At an offset of 0.3 mm, the thickness of the interfacial diffusion layer reaches 35.8 μm, and the maximum tensile strength reaches 406.9 MPa at this time. The fracture location is at the vanadium/stainless steel interface, and the fracture is characterized by ductile fracture.
