Method for electrical resistance welding thin metal sheets together for automotive vehicle structures |
摘要 |
A method for electrical resistance welding thin metal sheets together is disclosed. In the method, a protrusion is formed upon a first sheet wherein the protrusion includes a planar circular surface and an annular sloping wall. Thereafter, electrodes pass an electrical current through the protrusion as the protrusion is contacted with a second metal sheet for electric resistance welding the first sheet to the second sheet.
