(1)ステンレス系成分の溶接金属の亜鉛脆化割れ感受性は、溶接金属の凝固形態に依存し、フェライト単相で凝固が完了する成分系の溶接金属は、オーステナイト単相またはオーステナイトとフェライトの2相で凝固が完了する成分系の溶接金属に比べて亜鉛脆化割れの発生が少ないこと、
(2)亜鉛脆化割れの原因物質である亜鉛めっきに由来するZnなどの低融点成分は、Al2O3と結合しやすいため、Al2O3の添加によって溶接金属からAl2O3−ZnO系酸化物(スラグ)として排出できる
ことを新たに知見した。
(1)ステンレス系成分の溶接金属の亜鉛脆化割れ発生を抑制するために、溶接金属がフェライト単相で凝固完了するようにフラックス入り溶接ワイヤ中に金属または合金として添加するフェライト形成成分およびオーステナイト形成成分を適正化するとともに、
