METHOD FOR LASER WELDING WITHOUT ADDITION OF MATERIAL, AND ELECTRICAL DEVICE FORMED USING SAID METHOD |
摘要 |
The welding method is for connecting together first and second metal elements ( 20, 16 ). The first element ( 20 ) forms a support or is for being fitted onto a support ( 12 ). During the method, a welding portion ( 20 A) is formed in the first element ( 20 ), the welding portion having a connection end ( 22 ) connected to a support portion ( 20 B) of the first element ( 20 ). A free end face (F) is formed in the welding portion ( 20 A) of the first element ( 20 ) remote from the connection end ( 22 ). A high-energy beam ( 24 ) is directed onto the welding portion ( 20 A) of the first element ( 20 ) in such a manner that the axis (X) of the beam ( 24 ) passes through the welding portion ( 20 A) from the free end face (F) towards the connection end ( 22 ), thereby causing at least a portion of the mass of said first element ( 20 ) to melt, the molten mass coming into contact with the second element ( 16 ) by said mass collapsing. |
