Title: METHOD FOR LASER WELDING
Abstract:
There is described a method for welding a first panel to a second panel. The method comprises forming an approximate connection, such as a mortise-and- tenon or a tongue-and-groove connection, to preassemble the first panel and the second panel, thereby roughly creating a joint between the first panel and the second panel. With a laser camera, a location and a spatial orientation of the joint is determined using a tracking algorithm. A laser is eventually displaced at a given location which depends upon the location and the spatial orientation of the joint. The joint is then irradiated with the laser, while displacing the laser along the spatial orientation of the joint, to weld the first panel with the second panel.
