<p>A laser welding system utilizes a multiple axes positioner to angularly orient about orthogonal A and C axes and linearly position along orthogonal X and Y axes a fixtured parts assembly (62) such as to access weld sites at the top, bottom and all sides thereof. Linear ajustments of the position of the laser head (126) along a Z axis are made to maintain a constant beam focal length. Welding in an inert gas environment is thus facilitated, since the welding operation can be completed without human intervention to manually reposition the fixture. Interim purging to restore the requisite welding environment is therefore avoided.</p> |
