METHOD OF ONE-PASS ARC WELDING OF TITANIUM AND TITANIUM ALLOY ARTICLES OF THICKNESS FROM 10 MM AND GREATER OVER GAS-SATURATED EDGES Russian patent published in 2000 - IPC

Abstract RU 2156680 C1

FIELD: fusion welding; making of titanium structures of medium and higher thickness. SUBSTANCE: reduction of gas content in weld seam to tolerable values is provided owing to the fact that welding is carried out at relationship of main parameters of mode and penetration depth defined by empirical formula K = (1•U)/(V•H)<50•104kJ2 where K is coefficient defining amount of heat per welding bath surface unit; I is welding current, A; U is arc voltage, V; V is welding rate, m/s; is depth of penetration, m. EFFECT: improved quality of welds. 1 tbl, 1 ex
