The laser welding is the most promising solution to the Ni-Ti alloy welding， since it has various strengths such as high energy density， narrow welded joint， small welding heat affected zone， small weld-induced distortion， quite a small amount of metal being melted， good beam directionality， availablity for precision finishing， and so 希望你能满意！
Laser welding welding with higher energy density， narrow， small， welding heat affected zone distortion and melting metal quantity is little， beam directional good， can carry on the fine processing etc， and is the most promising NiTi alloy welding
