METHOD FOR REGULATION OF CONSUMABLE-ELECTRODE ARC WELDING Russian patent published in 1997 - IPC

FIELD: methods for production of joints with use of consumable-electrode arc welding. SUBSTANCE: method includes setting of standard values of parameters of welding conditions for stages of dribble formation and their transition. Regulations of variation of standard values are corrected in the process of welding with considerable of the process real conditions. Then virtual value of welding conditions parameter is registered in welding process at each moment of time, and welding process is regulated by correction of deviation of this parameter from the preset value. Welding conditions parameter used for the purpose is taken in the form of arc instantaneous power. EFFECT: higher efficiency. 6 dwg
