<p>PCT No. PCT/FR97/01459 Sec. 371 Date Feb. 8, 1999 Sec. 102(e) Date Feb. 8, 1999 PCT Filed Aug. 6, 1997 PCT Pub. No. WO98/06533 PCT Pub. Date Feb. 19, 1998A method and a system for laser beam welding two pieces abutted along a joint, wherein a camera configured to observe the joint is mounted integral with a welding head thereby defining a camera/welding head assembly. The camera/welding head assembly is moved along the joint and orthogonal positions of the joint are detected for positions of the camera/welding head assembly along the joint. A guiding mechanism guides a welding laser beam impact along the joint by controling an orthogonal translation of the camera/welding head assembly based on the orthogonal positions of the joint.</p> |
