Abstract EN
In this work experimental trials of welding of NiTi flat plates with 2.0 mm thickness were conducted using a 4.5 kW continuous wave (CW) Nd:YAG laser.
The influences of laser output power, welding speed, defocus amount and side-blow shielding gas flow rate on the morphology, welding depth and width, and quality of the welded seam were investigated.
Meanwhile, the effects of heat input on the mechanical and functional properties of welded joints were studied.
The results show that laser welding can take better formation in NiTi alloys.
The matching curves with laser power and welding speed affecting different formation of welds were experimentally acquired, which can provide references for laser welding and engineering application of NiTi alloy.
The heat input has obvious effects on the ultimate tensile strength (UTS) and shape memory behavior of the welded joints.
