Z408焊条药皮组分对焊接工艺性能的影响

Effect of coating composition of Z408 electrode on the welding technological property

研究了焊条药皮中添加石英、石墨、萤石、稀土镁、硅钙等对焊条电弧稳定性、渣的流动性、套筒长短、焊缝成形、飞溅大小、渣的覆盖性、脱渣性等焊接工艺性能的影响,结果表明,当上述成分添加量(质量分数)分别为8%,21%,12%,2%,10%时,其焊接工艺性能较好.

The technological property such as the arc stability,slag fluidity,seleeve length,appeararce of weld,spatter,slag covering degree and slag detachability are studied when the content of quartz,graphite,fluorite,magnesium_rare_earth and silitconcalcium are added to Z408 cast iron electrode.It is concluded that the technological property of the electrode is very good when their corresponding contents are 8%,21%,12%,2%,10%.
