  • Control method of arc welding and arc welder
    Patent number: 6744012
    Abstract: A control method for arc welding wherein position control of an electrode or a torch is performed while adjusting welding conditions on the basis of optical information obtained from arc light generated during an arc welding process. Illuminance, which forms the optical information obtained from the arc light, has a certain mutual relationship with the arc length or the torch height, so that the weld control is accomplished based on the illuminance. The control method includes a step of comparing illuminance with reference information based on the mutual relationship, and a step of adjusting the welding conditions on the basis of a result of comparison.
