PROCESS OF GAS AND POWDER LASER SURFACING BY TWO NOZZLE FEED OF POWDER Russian patent published in 1997 - IPC

Abstract RU 2100479 C1

FIELD: metallurgy. SUBSTANCE: powder is fed from one nozzle into head part of laser spot following movement of article. Powder form other nozzle is fed into central and tail parts of laser spot in opposition to movement of article. EFFECT: increased coefficient of usage of powder, decreased ratio of height of surfaced bead to width to prevent appearance of incomplete fusion on sides of bead. 1 dwg, 2 tbl
