摘要：

The　influence　of　iron　powder/feldspar　on　the　arc　stability,　average　particle　size,　Cr(VI)　content　and　Cr(VI)/　total　Cr(n/N)were　investigated　by　hanover　arc　analyzer,　high-speed　cameras　and　laser　particle　sizer.　The　experimental　results　showed　that　average　particle　size　of　welding　fume　inshort　circuit　transfer　is　smaller　than　the　granular　transfer;　The　proportion　of　Cr(VI)/　total　Cr(n/N)　is　low　in　welding　fume　of　short　circuit　transition.Under　the　same　welding　parameters,　welding　fumes　average　particle　size　is　up　to　1154　nm,　Cr(VI)　and　Cr(VI)/total　Cr　are　24%　and　1555.8　mg/kg　respectively　when　iron　powder/feldspar　is　around　1.8,　under　which　the　shortest　short　transition　time　is　1033　μs.　©,　2015,　Harbin　Research　Institute　of　Welding.　All　right　reserved.
