Abstract：

The　main　application　background　of　this　paper　is　using　laser　cladding　technology　to　process　high-speed　wire　roller.　The　production　lines　in　the　steel　rolling　industry　are　different.　The　wire　rollers　at　different　positions　in　the　produce　line　have　different　shape.　And　the　different　backings　of　rollers　have　different　process　crafts.　So　it　is　necessary　to　explore　the　mechanics　of　laser　cladding　roller　with　universality.　The　paper　analysed　the　laser　cladding　process　in　theory,　and　sought　one　measuring　and　tracing　method　adapted　to　analyzing　and　monitoring　laser　cladding　process.　Based　on　the　temperature　field　of　CO2　laser　cladding　investigated　through　high　speed　camera,　the　basic　things　about　how　to　analyze　temperature　field　by　Matlab　software　are　introduced,　including　input　and　output　of　the　thermal　image,　the　temperature　distribution　at　the　direction　and　its　section　in　molten　pool.
