welding: the welding equipment clamps the metal plates and performs laser welding along a set track to fixedly connect at least two metal plates with different thicknesses;
stamping forming: and performing punch forming by adopting a flat plate stamping process according to the drawing of the workpiece.
Specifically, the stamping forming step comprises the working procedures of blanking, punching and shaping, and the whole formed by welding the metal plates is directly stamped during stamping. In the welding step, the weld 30 formed by welding is linear. When the number of the metal plates is larger than that of the two metal plates, at least two metal plates with different thicknesses are required to be subjected to laser welding.
The application also relates to a workpiece processed according to the processing method of the metal workpiece with different thicknesses, the workpiece comprises at least two metal plate bodies with different thicknesses, the two metal plate bodies are welded and fixed, and the workpiece is integrally formed in a punching mode.

Two metal plate bodies with the thickness of 2mm are welded and fixed on two sides of the metal plate body with the thickness of 1.8mm to form two welding seams 30, and the two welding seams 30 are linear and parallel to each other. According to the drawing of a workpiece, a flat plate stamping process is adopted for stamping forming, so that two metal plate bodies with the thickness of 2mm become two longitudinal beams 20, and the metal plate body with the thickness of 1.8mm becomes a cross beam 10.
