Welding　spatter　cause　many　problems　during　the　welding　process　and　this　issue　is　particularly　important　for　cellulose　electrode　welding.　The　hot　flying　spatter　balls　often　deteriorate　the　working　environment,　and　decrease　the　welding　efficiency.　Many　factors　affect　the　welding　spatter,　and　metal　transfer　behavior　is　one　of　the　main　factors.　Many　studies　concerning　the　spatter　mechanism　in　arc　welding　process　were　made;　most　of　them　focused　on　the　solid　wire　welding　and　the　study　on　cellulose　electrode　is　rarely　reported.　In　this　paper　the　metal　transfer　behavior　and　the　weld　spatter　characteristics　of　three　commercial　cellulose　electrodes　were　studied　experimentally　by　using　a　high　speed　camera　for　visually　capturing　the　metal　transfer.　The　relationship　between　the　metal　transfer　and　the　welding　spatter　was　analyzed　experimentally　by　comparing　the　spatter　loss　coefficient,　which　is　for　quantitative　evaluation　of　welding　spatter,　with　the　statistical　analysis　of　the　large　droplet　transfer　mode.　The　results　showed　that　short　circuiting　transfer,　large　droplet　spray　transfer,　fine　droplet　spray　transfer　and　explosive　transfer　govern　the　metal　transfer　modes　in　cellulose　electrode　welding.　Weld　spatter　occurred　mainly　in　the　deflection　of　large　droplet　process,　explosive　transfer　process　and　fine　droplet　spraying　process.　Different　metal　transfer　modes　lead　to　different　spatter.　The　deflection　of　large　droplet　and　explosive　transfer　are　the　main　factors　of　the　spatter　formation.　Minimizing　the　droplet　size　and　reducing　the　deflection　of　large　droplet　and　explosive　transfer　leads　to　the　reduction　the　amount　of　spatter　in　cellulose　electrode　welding.
