PURPOSE: To easily perform stable multilayer welding with high precision by carrying out correction processing in consideration of one side at least of a groove shape and a weld bead shape just before the welding stage for every welding stage.
CONSTITUTION: Automatic picture processing groove teaching on all points is carried out and registered (S4) on a welding parameter table and a welding condition parameter is set (S5) from this set parameter. Robot control angle arithmetic processing is then carried out (S6) with respect to this welding parameter table and a program code of a numerical controller is produced in order and an NC program is produced (S7) automatically therefrom. A circuit for transferring data is used to register (S8) on a specified region of an NC data memory of the numerical controller. Thereafter, it is confirmed by processing of S10 whether or not the position of a welding torch it obtained suitably by test running of playback operation of the numerical controller and when necessary, it is returned to processing of S4. When unnecessary, playback automatic welding operation is started and satisfactory automatic welding is obtained.
