Panel pressing device applied to laser tailor-welding

The invention belongs to the technical field of laser welding, and particularly relates to a panel pressing device applied to laser tailor-welding. The panel pressing device comprises a pressing beam and pressing components, wherein the pressing beam is provided with a plurality of stepped through holes along the length direction; one set of the pressing component is arranged in each stepped through hole. According to a method, a plurality of groups of pressing components are used for vertically acting on a welded panel, and a plurality of groups of pressing load are applied, so that the welded panel can be pressed and fixed. The device disclosed by the invention has the advantages of being simple in structure, low in cost, convenient to dismount, replace and maintain and the like; the method is good in pressing effect, uniform in pressing force and high in panel correction quality; the panel can be effectively fixed; the requirements of laser tailor-welding on flatness of the pressed panel are satisfied; the welding quality are ensured not to be affected by cracking of the edge of the panel due to welding stress caused in a welding process.
