Title (EN) HIGH-CURRENT PULSED ARC WELDING METHOD AND FLUX CORED WELDING WIRE
(FR) PROCÉDÉ DE SOUDAGE À ARC PULSÉ À FORT COURANT ET FIL DE SOUDAGE À CŒUR DE FLUX
(JA) 高電流パルスアーク溶接方法及びフラックス入り溶接ワイヤ
Abstract: front page image
(EN) A pulsed arc welding method which uses a flux cored welding wire that contains at least one element selected from the group consisting of C, Si, Mn, P, S, Al, Ti, Zr and Mg, respectively in specific amounts, and wherein: the pulse peak current during the welding is set to 550-950 A; the pulse base current during the welding is set to 550 A or less; and the difference between the pulse peak current and the pulse base current is set to 200-600 A.
(FR) L'invention concerne un procédé de soudage à arc pulsé, lequel procédé utilise un fil de soudage à cœur de flux qui contient au moins un élément choisi parmi le groupe comprenant C, Si, Mn, P, S, Al, Ti, Zr et Mg, respectivement sous des quantités spécifiques, et dans lequel : le pic d'impulsion courant pendant le soudage est établi à 550 à 950 A ; le courant de base d'impulsion pendant le soudage est établi à 550 ou moins ; et la différence entre le pic d'impulsion de courant et le courant de base est établie à 200 à 600 A.
(JA) C、Si、Mn、P、S、Al、Ti、Zr及びMgからなる群より選ばれる少なくとも1の元素をそれぞれ特定量含むフラックス入り溶接ワイヤを用いるとともに、溶接時のパルスピーク電流を550~950A、パルスベース電流を550A以下、パルスピーク電流とパルスベース電流との差を200~600Aにするパルスアーク溶接方法。
