摘要：

The　surface　treatment　methods　were　investigated　to　control　the　weld　porosity　of　laser　welding　aluminum-lithium　alloy,　which　were　including　in　caustic　washing,　acid　pickling,　mechanical　polishing　with　stainless　steel　brush　and　laser　cleaning　in　this　paper.　The　effect　of　parameters　of　these　surface　treatment　procedures　on　the　distribution,　quantity,　size　and　characteristic　of　pores　in　the　welds　were　discussed.
