Title: Control method for constant arc length in pulse arc welding
Inventor: SARUTA HIROKI
IPC: B23K9/127
Filed: 1985-03-19
Abstract: PURPOSE:To enable a continuously stable constant arc length control even in low frequencies zone by controlling the position of welding electrode so as to make the differential voltage zero between arc voltage and the arc length setting signal formed with the correction of the reference voltage by the differentical voltage in the arc voltages in high and low current periods. CONSTITUTION:The arc voltage Vb in low current period is compared with the reference arc voltage Vref in said period. In high current period, the arc voltage Vbh detected and stored in the low current period is subtracted from the arc voltage Vph detected and stored in said high current period. The arc length is then controlled by comparing that corrected with addition of the reference arc voltage Vref by the differential voltage in the both and the arc voltage Vp. Namely the control of the arc length is performed in not only low current period but also high current period. The control of the arc length is therefore performed continuously and the uncontrollable period is virtually eliminated even in the flow frequency zone of about 0.5-2Hz and the responsibility is increased as well accordingly.
