| 摘要 |
The invention relates to an electric resistance spot welding device. According to the invention, the device comprises two subassemblies which are symmetrical in relation to a plane (a) of the weldings, each of said subassemblies comprising an internal body (1) and an external body (2) hingedly mounted onto the arms of the universal welding machines, on the internal body (1), one, two, three, four or five supports (5) of some spot-welding electrodes (6) being positioned on some guides (b) or on some guiding bars, said positioning being made at suitable distances, symmetrically adjustable in relation to the plane of the axes of the universal welding machine arms (4), by using some right-left screws (7). A number of weldings equal to the number of electrode pairs is achieved simultaneously.
