The invention is applicable to the technical field of lasers and discloses a laser welding method for high-reflection metal parts. The laser welding method is used for welding a first connecting piece and a second connecting piece made of high-reflection metal materials. The laser welding method comprises the following steps of texturing processing, clamping, laser welding and withdrawing, wherein in the texturing processing step, the welding surface of the first connecting piece and / or the welding surface of the second connecting piece is subjected to texturing processing, and a texturing structure and an oxide film layer are formed on the welding surface of the first connecting piece and / or the welding surface of the second connecting piece; in the clamping step, a fixture is used for tightly clamping the first connecting piece and the second connecting piece; in the laser welding step, a laser welding device is used for illuminating the texturing structure and the oxide film layer with lasers, and the first connecting piece and the second connecting piece are connected to form a welding assembly; in the withdrawing step, the fixture is loosened, and the welding assembly is withdrawn. The laser welding method successfully solves the problems that in the prior art, when the laser welding technology is adopted to weld the high-reflection metal parts, the laser reflectivity is high, the welding energy is high, and the welding quality is poor.
Description
technical field [0001] The invention belongs to the field of laser technology, in particular to a laser welding method for high-reflection metal parts. Background technique [0002] The rapid rise of international oil prices and abnormal changes in the global climate have led people to attach great importance to energy security and environmental protection, and people have listed energy crisis and environmental pollution as two social problems that need to be solved. The large number of applications of fuel vehicles has been regarded as one of the main reasons for the energy crisis and environmental pollution. Therefore, in order to reduce the application of fuel vehicles, relevant technical personnel have proposed a plan to vigorously develop electric vehicles to replace fuel vehicles with electric vehicles. And achieved the diversification of energy sources, reducing pollution and improving energy efficiency. [0003] The battery is the energy component of the electric ve...
