Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following examples.

[0022] The laser welding method of the metal thin plate provided by the present embodiment comprises the following steps: (1), two welding workbenches 4 are arranged perpendicular to the direction of the welding machine main body 1, and a material preparation area is set on the left and right sides of the welding workbench 4, Place the metal sheets to be welded in the preparation area, such as figure 1 shown. The metal sheet separating device is installed in the material preparation area, which is convenient for taking the metal sheet.

[0023] (2) The finished board stacking area is set in front of the welding workbench. The surrounding areas of the material preparation area and the finished board stacking area are relatively open, and the raw materials or welding finished products ...

Abstract

The invention provides a laser welding method for metal sheets. The laser welding method comprises the following steps that two or more welding worktables are arranged in the direction perpendicular to a welding machine body, and material preparing areas are arranged on the left sides and the right sides of the welding worktables; finished plate stacking areas are arranged in front of the welding worktables; one or more metal sheets in each material preparing area are taken and placed on the corresponding worktable; a laser welding machine is started, a welding head is started for welding operation and moves in the welding seam direction until welding of the two metal sheets on the corresponding worktable is finished; and a welding arm moves towards the second welding worktable, welding is carried out, and meanwhile the welded sheets on the first welding worktable are taken down and placed in the corresponding finished product or semi-finished product stacking area. The steps are repeated, and therefore efficient metal sheet laser welding is achieved. The invention provides a novel laser welding method for the metal sheets. According to the method, the production efficiency can be greatly improved by changing an existing working mode.

Description

technical field [0001] The invention provides an efficient laser welding method, in particular relates to a laser welding method for thin metal plates, and belongs to the technical field of laser thin plate welding. Background technique [0002] Tailored laser welding technology is a green and environmentally friendly high-tech laser flexible processing technology that is vigorously promoted by the country and is developing at a high speed. Tailored laser welding technology can realize the direct tailor welding of sheets of different materials, different thicknesses and different coatings through high-power laser, and achieve different mechanical properties and coordination in different areas on a steel plate (laser tailor welded blank) Requirements to meet the design and manufacturing requirements and safety performance of complex parts. [0003] Take the manufacture of the front longitudinal beam sub-assembly of the automobile as an example: the left and right front longi...
