  • Arc welding control system and method
    Patent number: 10144081
    Abstract: The present invention provides an arc welding control system and method capable of simultaneously, sophisticatedly performing a weaving width control operation and a torch height control operation. Influence ratios (?w and ?z) of influences of a torch height deviation (?Ph) and a groove wall distance deviation (?Pd) with respect to a manipulated variable (?w) of a weaving width and a manipulated variable (?z) of a torch height are set in accordance with a groove angle (?) of a workpiece (5). A calculation unit (21) calculates the manipulated variables (?z and ?w) of actuators (13 and 14) regarding the torch height and the weaving width such that the influence ratios (?w and ?z) become large as the groove angle (?) becomes large.
    Type: Grant
