The butt fusion welding of four different grades of polyethylene pipe has been studied and the feasibility of producing good welds between pipes of different melt flow index has been examined. Weld quality has been assessed on the basis of tensile tests and microstructural studies. The factors influencing the microstructure are discussed; in particular, the flow of molten polymer within the welds.read more

Hot plate welding of plastics: Factors affecting weld strength
TL;DR: This article showed that weld strength is strongly affected by hot plate temperature, heating time and melt flow during welding, and that excessive heating or melt flow produces strong transverse orientation, but in different ways, which can be distinguished by fracture mechanics tests.

Some microstructural features of the welds in butt-welded polyethylene and polybutene-1 pipes
P. Barber,J. R. Atkinson +1 more
TL;DR: In this article, microstructural features characterizing butt welds in polyethylene and polybutene-1 pipes have been studied using scanning electron and transmission optical microscopy, and the microstructures are explained on the basis of temperature gradients measured in the region of the welds and the flow of molten material during welding.
