METHOD FOR PREPARING FOR WELDING EDGES OF SHEET BLANKS OF TITANIUM ALLOYS Russian patent published in 2003 - IPC

Abstract RU 2196032 C1

FIELD: fusion welding of blanks of titanium alloys, possibly in different branches of national economy for making welded constructions. SUBSTANCE: method comprises steps of treating edges of sheet blanks by cutting in atmosphere of technical nitrogen by means of focused laser irradiation with specific linear power density Ffl = Ef/Vl, where Ef - power density of laser irradiation equal to (7.3-9.8)10-5 Wt/sq.cm; Vl - cutting speed equal to 2.2-2.6 m/min. EFFECT: possibility for missing multiple intermediate technological operations at preparing edges for welding, enhanced quality of edge surface. 1 tbl
