  • Method and device of correcting a welding path of an automatic welding apparatus
    Patent number: 5653902
    Abstract: A method and device of correcting a welding path of an automatic welding apparatus are disclosed. In order to prevent the deviation of a welding torch from the predetermined welding path due to deformation of structure, a position correction amount is used. The position correction amount is determined by setting a mean welding current for the up-down direction position correction, which is determined by averaging the welding current, and by setting a weight value for the left-right direction position correction, in which the weight value is determined by multiplying the welding current by a weight factor, thereby a welding torch follows the predetermined welding path precisely.
