The present application belongs to the technical field of
laser welding, and particularly relates to a high-efficiency and environment-friendly
copper plate
laser welding device and a
welding method thereof, which comprises a welding box and a control box installed on one side of the welding box, an end surface of the welding box is provided with a welding table, an end surface of the welding table is provided with a detachable clamping mechanism, the clamping mechanism is used for fixing the
copper plate radiator on the welding table, and the device further comprises a plurality of movable blocks, the movable blocks are arranged above the welding box, each movable block is provided with a
wire drawing and
polishing assembly, and the welding box is provided with a pushing mechanism, which is used for pushing each movable block to move along each welding seam of the
copper plate radiator. The present application can improve the fusion degree and welding strength of the heat dissipation fin and the copper plate during
laser welding, can reduce the generation and escape of welding
waste gas, can improve the air environment, has good
environmental protection effect, can automatically optimize the welding
time based on the
waste gas concentration, and can guarantee the consistency of the welding strength.
