PURPOSE:To simplify teaching work and to reduce time by teaching only one point of a reference point, reading welding loci, welding conditions and torch angles from a storage means in accordance with said one point and giving working instructions. CONSTITUTION:The tip of a welding torch is brought to a reference point P0 to teach a welding pattern. The tip is brought to the point P1 to teach a welding pattern. Similar teaching operation are repeated with P2, P3 as well. After the torch is rotated 180 deg., the above-mentioned teaching operations are repeated with points P4-P7 as well. However, the welding patterns used at the points P0-P3 are used for the welding pattern after the rotation by 180 deg.. Since errors in setting of the work, position deviation, etc. arise after the rotation by 180 deg., it is desirable to perform teaching even after the rotation by 180 deg.. |
