Plastic pipe, Simulation analysis, Quality evaluation.Abstract
In this paper, aiming at the welding quality problems of plastic pipes, finite element analysis method was used to evaluate the quality of welded joints through temperature, melting layer and stress. The results showed that: the crystallization degree and heat transfer distance of the welded surface and its heat-affected zone were different, resulting in different properties of welded joints. Stress stabilization will increase polymer apparent viscosity and reduce melt flow capacity, thus reducing residual stress.
