PURPOSE:To improve greatly welding operability, by teaching points for a weaving pattern in an optional space and moving the respective taught points in parallel, and generating a pattern consisting of segments between respective points which are enlarged or reduced at a specific ratio. CONSTITUTION:A welding line is taught previously while its starting and ending points are indicated by Q1 and Q2. On the other hand, taught points P1, P2, and P3 having the same length and direction in an exactly different space from the welding line are provided. The respective points are shifted in parallel by the same extent and direction with the segment P1Q1 between the points Q1 and P1 to obtain points P'1, P'2, and P'3. The execution direction of the weaving pattern is determined in the order of the points P'1, P'2, P'3, and P'1. For weaving amplitude, a point P''2 is provided on the segment P'1P'2 parallel to the segment P1P2 at specified distance from the point P'1, and a segment parallel to the segment P'2P'3 from the point P'' is denoted as P''2P''3, so that the weaving pattern consisting of enlarged or reduced segments connecting the points P'1, P''2, P''3 is generated. |
