Abstract
Description
図1は、本発明のフラックス芯溶接ワイヤ1の構造を示す概略図である。図1に示すように、フラックス芯溶接ワイヤ1は外殻16を備える。外殻16は管状(または円形)の形状をなし、その中に管状(または円形)の空洞17(図5に示す)を有し、空洞17はその軸方向に沿ってフラックス12が充填される。一実施形態では、溶接ワイヤ1は、1.4mmの直径を有するように形成することができるが、実際の使用法および要件によっては、他の直径も可能である。例えば、使用法に基づいて、フラックス芯溶接ワイヤ1の直径は1.2mmまたは1.6mmにすることができる。
通常使用される400系ステンレス鋼に含まれる重量比による組成物の割合は以下の通りである。
表2:選択された410ステンレス鋼帯内の組成物の割合(重量パーセント)
本発明を更にわかりやすく例示するために、410ステンレス鋼帯および炭素鋼帯の機械的パラメーター間の比較が以下のように記載される。
炭素鋼帯から作製されるフラックス芯溶接ワイヤは容易く錆びる。炭素鋼帯から作製される通常のフラックス芯溶接ワイヤは、約2週間空気にさらされた後に錆びつく。錆びた溶接ワイヤが通常の使用に対する要件を満たす見込みはほとんどない。然しながら、400系ステンレス鋼は耐食特性を有する。従って、400系ステンレス鋼は錆問題を効率的に解決し、それにより、フラックス芯溶接ワイヤの保管条件に対する要件を実質的に下げ、かつフラックス芯溶接ワイヤの保管時間を延ばす。
本発明の400系ステンレス鋼外殻を有するフラックス芯溶接ワイヤは小さな抵抗を有し、それにより、フラックス芯溶接ワイヤの溶接特性を改善する。
