Title (EN) ARC WELDING METHOD
(FR) PROCÉDÉ DE SOUDAGE À L'ARC
(JA) アーク溶接方法
Abstract:
(EN) The purpose of the present invention is to provide an arc welding method with which the generation of spatter can be reduced, and which provides good slug agglomeration even at high welding rate. An embodiment of the present invention relates to an arc welding method for welding a steel sheet while a weld wire is feed-controlled in forward and backward directions. The arc welding method includes performing the welding using: a weld wire which contains C and, by mass%, not less than 0.2% and not more than 1.3% of Si, not less than 0.2% and not more than 1.5% of Mn, and not less than 0.01% and not more than 0.05% of S, with the remainder comprising Fe and unavoidable impurities; and a gas including Ar. The frequency of the weld wire in the forward and backward directions is not less than 35 Hz and not more than 160 Hz.
(FR) Le but de la présente invention est de fournir un procédé de soudage à l'arc avec lequel la génération d'éclaboussures peut être réduite, et qui assure une bonne agglomération de quantité de matière même à un taux de soudage élevé. Un mode de réalisation de la présente invention concerne un procédé de soudage à l'arc destiné à souder une tôle d'acier alors qu'un fil de soudage est commandé en avant et en arrière. Le procédé de soudage à l'arc comprend la réalisation du soudage en utilisant : un fil de soudage qui contient C et, en % massique, pas moins de 0,2 % et pas plus de 1,3 % de Si, pas moins de 0,2 % et pas plus de 1,5 % de Mn, et pas moins de 0,01 % et pas plus de 0,05 % de S, le reste comprenant du Fe et des impuretés inévitables; et un gaz comprenant Ar. La fréquence du fil de soudage dans les directions avant et arrière n'est pas inférieure à 35 Hz et ne dépasse pas 160 Hz.
(JA) 本発明は、スパッタの発生を低減できるとともに、溶接速度を速くしながらも、スラグ凝集性も良好なアーク溶接方法を提供することを目的とする。本発明の一態様は、溶接ワイヤを進退方向に送給制御しながら、鋼板を溶接するアーク溶接方法であって、Cを含有するとともに、質量%で、Si:0.2%以上1.3%以下、Mn:0.2%以上1.5%以下、及びS:0.01%以上0.05%以下を含有し、残部がFeおよび不可避的不純物からなる溶接ワイヤと、Arを含むガスと、を用いて、溶接ワイヤの進退方向の周波数を35Hz以上160Hz以下として溶接を行うアーク溶接方法に関する。
