Hemming and in-situ laser welding method and apparatus |
摘要 |
A hemming and in-situ laser welding method and apparatus for hemming peripheral flanges of an outer steel panel over peripheral edges of an inner steel panel and laser welding the resulting hemmed joints. A lower die supports an outer metal panel in a position to be hemmed over an edge of an inner panel. An upper die is mounted on a movable support for reciprocal motion and hems the outer panel by folding a flange of the outer panel over onto an edge region of the inner panel when the upper die moves from a raised position to a down position. A laser unit welds the flange of the outer panel to the edge region of the inner panel with the upper die in its down position holding the two panels together.
