ARC STOP IN WELDINGとは 意味・読み方・使い方

In the square wave alternating current arc welding method, the arc is started in the reversed polarity when the time from the stop of the arc to the restart of the arc has exceeded a threshold value, and is started in the straight polarity when the time from the stop of the arc to the restart of the arc has not exceeded the threshold value.例文帳に追加

アーク中断から再スタートまでの時間が閾値を越えたときは、アークスタート時の極性が逆極性でスタート、閾値を越えないときは正極性でスタートする方形波交流アーク溶接方法。 - 特許庁

To solve problems that it takes a long useless time from the start of feeding of a welding wire to practically the generation of arc because of a reduction in slow-down speed for improving the starting property of the arc, and the efficiency of the welding working time is low, in the welding repeated at a short interval between the start and the stop of the welding.例文帳に追加

溶接開始と停止とを短い間隔で繰り返す溶接において、アークスタート性を良好にするためにスローダウン速度が遅いため、溶接ワイヤの送給開始から実際にアークが発生するまでの無駄時間が長くかかり、溶接作業時間の効率が悪い。 - 特許庁

To solve such problems that a ball of a wire end at the completion of an welding is not formed in a proper shape, which causes an arc start error that requires a production line stop or extra-aftertreatment, and which leads to a productivity decline.例文帳に追加

溶接終了時のワイヤ先端の玉を適正形状に形成することができずにアークスタートミスが発生し、生産ライン停止や余分な後処理が必要となり生産性の低下を招く。 - 特許庁

A steel sheet having a tensile strength of ≥800 MPa which has excellent brittle fracture propagation stop properties is subjected to cold working, so as to be formed into a pipe shape, and thereafter, the butted parts thereof are welded by a hybrid welding process in which laser welding using CO_2 gas shield and gas shielded arc welding using Ar-CO_2 gas shield are combined.例文帳に追加

脆性亀裂伝播停止特性に優れた引張強度８００ＭＰａ以上の鋼板を冷間加工で管状に成形した後，突合せ部を、ＣＯ_２ガスシールドを用いたレーザーとＡｒ−ＣＯ_２ガスシールドを用いたガスシールドアーク溶接を組合わせたハイブリッド溶接法によって溶接する。 - 特許庁
