Title: Automatic multi-layered welding method for horizontal butt joint
Inventor: MATSUMURA HIROYUKI
IPC: B23K9/095
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the precision of the multi-layered multipath welding of the horizontal butt joint by sensing a groove shape before the final path operation of each layer. SOLUTION: Before the operation of a 4th path as the final path of a 4th layer, sensing is carried out to securely detect feature points of the groove shape. After the sensing, a CCD image is obtained through a CCD camera. At a detection point C, an inflection point is obtained without being affected by a welding bead shape, so detection precision is improved. In the performance order of groove welding, a path to be welded is set as a 1st path of each layer according to information obtained from the detection point C and the 1st path is welded first. Information after the sensing is utilized immediately for next welding, so the detection point C is never embedded as a result of other welding and a welding torch can perform operation securely at an aimed position.
