摘要：

A　laser　vision　sensing　based　adaptive　TIG　welding　system　for　large-scale　aluminum　alloy　components　was　established　to　fit　for　the　variety　of　weld　groove　conditions.　A　new　type　laser　vision　sensor　was　used　to　precisely　measure　the　weld　groove.　The　joint　geometry　data,　such　as　bevel　angle,　gap,　area,　mismatch　and　etc,　could　be　used　in　assembling　large-scale　aerospace　components　before　welding　and　were　applied　for　automatic　seam　tracking　in　welding.　An　adaptive　welding　process　is　realized　by　automatically　adjusting　the　wire　feeding　speed　and　the　welding　current　according　to　the　groove　conditions,　with　good　weld　formation　and　high　welding　quality　which　meet　the　requirements　of　the　relative　standards.
