Abstract
A method and apparatus for in-situ laser welding of a hemmed joint are applicable for, among other things, production of vehicle doors having inner and outer panels to be joined. In a preferred method, the laser welding of a hemmed joint is carried out while a stable condition is maintained between the inner and outer panels. Locating members of a hemming machine are engaged with the metal sheets to be joined and a compressive force is applied to the panels. A plurality of welding units may be sequentially or simultaneously controlled by a computer. The apparatus includes a first portion for vertically locating the hemmed joint and a second portion for horizontally locating the hemmed joint.
