چکیده مقاله:
The purpose of this article is to study and recognize the rheological behavior in Friction stirwelding on polyvinyl chloride. For this purpose, the first welded sheets of PVC were prepared.Determination of stability, determination of critical stress, and differentiation of viscoelasticlinear region from Non-linear region and its rheological behavior were studied using a remoter.Rheological parameters are measured using rheological values and the Assumption of meltviscoelastic behavior of the Maxwell and developed Maxwell models, time relaxation andviscosity index were calculated and specified. It was found that with increasing temperatureand also increasing welding speed, the viscosity index and comfort time show a decreasingtrend.
