Abstract
【解決手段】ワイヤはワイヤの全重量を基準にC:0.03〜0.10%、Si:0.45〜1.05%、Mn:0.90〜1.90%、P:0.030%以下、S:0.030%以下、残部がFe及び不純物から構成され、下記の式で定義されるワイヤの消耗によるワイヤキャスト径の減少比が0.55以下であるガスシールドアーク溶接用メッキなしソリッドワイヤの組立体。
(ここで、Cfはスプールの上部に巻き取られたワイヤのキャスト径、及びCoはスプールの下部に巻き取られたワイヤのキャスト径を表わす)

Description
Cは溶接ワイヤ及び溶着金属の強度を向上させる元素であって、ワイヤ中の含量が増加することにより、溶接時にスパッタの発生量を増加させる。0.03%未満では、溶接ワイヤ及び溶着金属の強度が余りにも低くなり、0.10%を超えると、溶接時にスパッタの発生量が多くなる。
Siは溶融金属の流動性を向上させ、溶接時の溶接ビードの広がり性を良好にし、金属が強度を確保するための必須成分であり、溶融金属内の脱酸反応を助けて溶着金属上にスラグを形成させる。0.45%未満では、溶接ワイヤ及び溶着金属の引張強度と溶融金属の流動性が下がり、1.05%を超える場合は、高電流溶接時のビードの垂れ現象及び容積の流動性が増加し、容積の揺れが発生してアークが不安定になる。
Mnは、Siと同様に溶融金属の脱酸反応を助けて溶着金属上にスラグを形成させ、溶接ワイヤ及び溶着金属の強度を向上させる。0.90%未満では、溶接ワイヤの引張強度及び溶着金属の適切な表面張力が確保できなく、1.90%を超える場合は、溶接時に容積内の活性酸素量を減少させて容積の表面張力を増加させる。
Pは、金属に不純物の形態で存在し、低融点化合物を作って高温亀裂感受性を増大させる。0.030%を超える場合は、高温亀裂の原因になる。
Sは、Pと同様に低融点化合物を作って高温亀裂感受性を増大させる。0.030%を超える場合は、高温亀裂の原因になる。
