METHOD OF ADJUSTMENT OF ARC LENGTH BY VALUE OF VOLTAGE IN IT |
| 摘要 |
FIELD: electric arc welding. SUBSTANCE: component of voltage in arc is kept to preset value independent of current in it. Component of voltage is computed as difference between voltage measured in arc and product of its current by computed dynamic resistance of arc. EFFECT: increased quality of weld. 2 dwgn
