Method and apparatus for welding line tracer control |
摘要 |
In welding effected by weaving an electrode, welding current or voltage is applied to a frequency analyzer, for deriving a frequency component having the same period as a weaving period and a doubled frequency component having a period which is half the weaving frequency. The center of weaving motion is corrected in relation to the two frequency components to thereby effect tracer control for the electrode.
