ARC WELD CURRENTとは 意味・読み方・使い方

To provide a submerged arc welding machine scarcely causing weld defects even in high current-density welding.例文帳に追加

高電流密度溶接でも溶接欠陥が発生しにくい、サブマージアーク溶接機を提供する。 - 特許庁

To suppress the deterioration of weld quality owing to an arc magnetic blow phenomenon caused by the current of arc welding without providing a magnet, etc., giving a magnetic field and a magnetic force from the outside to a weld zone and an arc in an automatic welding method using the arc welding where welding wire is used as an electrode.例文帳に追加

溶接ワイヤを電極とするアーク溶接を用いる自動溶接方法において、溶接部やアークへ外部から磁界、磁力を与える電磁石などを設けることなく、アーク溶接の電流で生じるアーク磁気吹き現象による溶接品質の低下を抑制する。 - 特許庁

To obtain a satisfactory circumferential weld bead to a tubular material bevel joint requiring multilayer welding and bead patching per welding pass by nonconsumable electrode pulse arc welding or direct current arc welding.例文帳に追加

多層盛溶接及び溶接パス毎のビード継ぎが必要な管材開先継手に対して、非消耗性電極パルスアーク溶接又は直流アーク溶接により良好な円周溶接ビードを得る。 - 特許庁

To provide a solid wire for Ar-CO_2 mixed gas shielded arc welding which is good in welding workability and is excellent in the strength and stable toughness of weld metal even if high-efficiency welding is performed under welding conditions of a high electric current, high heat input and high interpass temperature.例文帳に追加

高電流、高入熱、高パス間温度の溶接条件で高能率な溶接を行っても、溶接作業性が良好で、溶接金属の強度および安定した靱性に優れるＡｒ−ＣＯ__2混合ガスシールドアーク溶接用ソリッドワイヤを提供する。 - 特許庁

Therefore, by a control like making the average current or the average voltage equal to a standard value as usual, there are problems that an arc is not stable, the depth of penetration of welding and weld width are changed with the elapse of time depending on a welding condition, and stable welding has been hard to various conditions.例文帳に追加

従って、従来のように平均電流又は平均電圧を基準値と合わせるような制御では溶接条件によりアークが安定せず、溶接の溶け込み深さや溶接幅が時間と共に変化したりする問題が有り、種々の条件に対して安定した溶接が困難であった。 - 特許庁

To provide a solid wire for carbon-dioxide shielded arc welding which has satisfactory welding usability, and attains the excellent strength and stable, excellent toughness of weld metal even when welding with high efficiency is performed under high electric current, high heat input and high interpass temper ature.例文帳に追加

高電流、高入熱、高パス間温度の溶接条件で高能率な溶接を行っても、溶接作業性が良好で、溶接金属の強度および安定した靱性に優れる炭酸ガスシールドアーク溶接用ソリッドワイヤを提供する。 - 特許庁

To solve a conventional problem in which burn through, weld bead defects, etc., are liable to occur, as a result of gradual increase in the welding current average value through change in fusion characteristics, which are caused by oxidation advanced on a wire surface with the lapse of time after the sealed package of the welding wire is opened, in the AC pulsed arc welding of aluminum alloys, for example.例文帳に追加

アルミニウム合金等の交流パルスアーク溶接において、溶接ワイヤを密封包装から開封後の時間経過に伴ってワイヤ表面の酸化状態が促進されることによって溶融特性が変化して溶接電流平均値が次第に増加し、その結果、溶け落ち、溶接ビード不良等が生じやすくなる。 - 特許庁
