METHOD FOR GAS-FLAME TREATMENT OF MATERIALS Russian patent published in 2003 - IPC

Abstract RU 2217273 C2

FIELD: welding processes and equipment, possibly apparatuses for gas- flame treatment of materials. SUBSTANCE: method comprises steps of forming working voltage and generating control signal for controlling working current of unit sources of gas mixture; providing successive supply of liquid into sources of gas mixture; combining gas fluxes; forming gas cushion over unit source of gas mixture; after transporting apparatus for performing the method correcting level of gas cushion due to passing low current of working voltage through source of gas mixture; then setting working electric current. EFFECT: significantly simplified design of apparatus. 25 cl, 27 dwg
