METHOD OF CONTROL OF LENGTH OF A C ARC BY VALUE OF VOLTAGE IN IT WHILE CONSUMABLE ELECTRODE IS USED FOR WELDING |
| 摘要 |
FIELD: electric arc welding. SUBSTANCE: invention refers to automatic control of process of electric arc welding. Voltage of initial firing of arc that is measured in it in zone of transition of its current through zero value is employed as feedback signal over length of arc. EFFECT: increased quality of weld thanks to enhanced precision of maintenance of length of arc. 2 dwgh
