Laser welding machine for the welding of sections in large structural components

摘要

Laser welding machine for the welding of sections to large structural components, comprising two laser units (1 and 2) mounted on a support which can move along the X, Y, Z axes. The two laser units (1 and 2) aim the laser beams through a structure which is symmetrical with respect to the focal axis. This structure comprises conduits (1.2) and articulated joints (1.1) provided with internal mirrors which direct the laser beams to the outlets (1.3 and 2.3). In use, the outlets (1.3 and 2.3) would be located on both sides of a section being welded, converging on the focal axis. The two outlets (1.3 and 2.3) are located on supports mounted on a head (7) which is rotatable about three axes (X', Y', Z') at the same time as these supports are moveable axially in either of two perpendicular directions.
