PURPOSE:To perform the welding under a satisfactory condition by teaching the bottom, a shoulder part, etc., of a cross-sectional shape of a groove and allowing a welding machine to recognize the cross-sectional shape of the groove and the welding position and selecting the suitable welding condition automatically. CONSTITUTION:In a welding starting pint A, this welding starting point A, and points B and C situated at wall surface 2 edges of the groove on the cross section of the groove are taught. The welding starting point A indicates a weld line 3 and the points B and C of the wall surface edges of the groove together with the welding starting point A are situated at the necessary and minimum positions to indicate the groove shape in the cross section of the groove. Moreover, in a welding finishing point H, only this welding finishing point H is taught and the finishing point H indicates the weld line 3. Moreover, points I and J are the points of the wall edges of the groove in the welding finishing point H. The welding position is discriminated by a robot for welding based on such teaching data. |
