An apparatus is disclosed for positioning, clamping and welding together proximal edge portions of two sheet blanks. The apparatus incorporates a high energy laser and sheet clamping mechanism used to clamp each sheet blank in place between an associated electromagnet and ferromagnetic clamping shoes. The shoes are positioned above a corresponding electromagnet and are vertically movable theretowards on the activation of the electromagnet. In use, the sheets are held in place with the respective sheet blanks sandwiched between the associated electromagnets and shoes with the proximal edge portions of the sheets abutting. The high energy laser is movably provided in the apparatus to move an emitted laser beam along a predetermined path over the abutting proximal edge portions to perform welding operations.
L'invention porte sur un appareil servant à positionner, bloquer, et souder ensemble, les bords proximaux de deux tôles. L'appareil comprend un laser de forte puissance et un mécanisme de blocage de chacune des tôles en position de soudure les prenant entre un électroaimant et des enclumes ferromagnétiques. Les enclumes sont placées au-dessus des électroaimants correspondants vers lesquels elles se déplacent verticalement lors de l'activation des électroaimants. Pour la soudure, les tôles sont maintenues en place en étant respectivement prises en sandwich entre les électroaimants et les enclumes correspondantes, alors que leurs extrémités proximales se touchent. Le laser de forte puissance se meut à l'intérieur de l'appareil de manière à faire circuler son faisceau le long d'une trajectoire prédéterminée au-dessus des bords proximaux des deux tôles se touchant et opérer la soudure.
