(a)スラグ形成剤におけるTiO2含有量を高くし比較的高い融点の凝固スラグを形成すると共に、スラグ形成剤の総量を比較的多くすることによって溶接金属を高温状態で良好に包囲することが可能となり、溶接止端部への溶融亜鉛の侵入を防止できる、
(b)スラグ形成剤におけるTiO2含有量の上限を規定し、溶接ワイヤ先端から鋼板母材に移行する溶滴の移行特性を安定化させることによってスパッタの低減が可能となり溶接作業性が向上する
ことを技術思想とする。
さらに、亜鉛系合金めっき成分として、塗装後耐食性を向上させるためCa、Be、Ti、Cu、Ni、Co、Cr、Mnの1種または2種以上の元素を添加しても良い。
まず、亜鉛脆化割れ抑制効果の確認のため、溶接材料の効果およびめっき種類の影響を調べた。
A:JIS G 3302に準拠した溶融亜鉛めっき鋼板
B:JIS G 3317に準拠した溶融亜鉛−5%アルミニウム合金めっき鋼板
C:Zn−11%Al−3%Mg−0.2%Siめっき鋼板
なお、めっき原板の鋼板成分には、C=0.08%、Si=0.02%、Mn=1.1%、P=0.015%、S=0.007%、Al=0.02%、B=0.0015%、N=0.003、Ti=0.01%の鋼板を用いた。
本発明であるワイヤNo.1〜7は、F値、TiO2、SiO2、ZrO2、Al2O3、スラグ剤の合計量、およびスラグ剤合計量に対するTiO2の比率が適正であるので、溶接金属、母材熱影響部共に割れが発生せず、溶接時の作業性も良好な結果となった。
