摘要
TheprocesspropertiesandinterfacebehaviorofCO2laserbrazingwithautomaticwirefeedforgalvanizedsteelsheetswereinvestigated,inwhichthebrazingfillermetalwasCuSi3andnofluxwasused.Astotheappearancequalityofthebrazingseams,therolesoftheprocessingparameters,suchasbrazingspeed,wirefeedingrate,inclinationandfeedingdirectionofthewire,laserpower,spotdiameterandheatingposition,wereassessed.ThefurtherinvestigationindicatesthatthebehavioroftheactiveelementsSi,MnandZnaresignificantlyinfluencedbyenergyinput.Attheinterface,themicrostructureofthebasemetalwascomposedofcolumnarcrystalsandtheacicalarαsolidsolutionwasfoundonthefillermetalside.
