METHOD FOR LASER WELDING WITHOUT ADDITION OF MATERIAL, AND ELECTRICAL DEVICE FORMED USING SAID METHOD

摘要

The invention relates to a welding method for interconnecting first metallic elements (20) and second metallic elements (16). The first element (20) forms a support or is to be added to a support (12). During said method, a welding part (20A) provided with a connecting end (22) for connecting to a supporting part (20B) of the first element (20) is formed in the first element (20). A free end face (F), opposing the connection end (22), is formed in the welding part (20A) of the first element (20). An energetic beam (24) is directed onto the welding part (20A) of the first element (20) in such a way that the axis (X) of the beam (24) passes through the welding part (20A) from the free end face (F) towards the connecting end (22), causing at least one part of the mass of the first element (20) to melt, the melted mass coming into contact with the second element (16) by the collapsing of said mass.
