The partial penetration lap laser welding is a solution for the disadvantages of resistant spot welding Stainless steel rail way vehicles such as poor surface quality and poor airtight.The effects of the laser welding process parameters such as laser power,welding speed and focused distance on the shape of the weld seam and the shear tensile strength were investigated.We will find the appropriate parameters at which the joint has higher shear tensile strength than that of RSW and no welded traces on the exterior surface of the car body.The work can afford pilot basis for the application of laser welding in stainless steel railway vehicles manufacturing.
