IR Welding of Glass Filled Polyether Sulfone Composite

A prototype infrared welding (IR welding) system was designed and constructed. Evaluation of IR welding process was performed including effects of process parameters on joint strength and microstructural analysis. IR welding can be divided into three phases, which are heating of the joint surfaces, change-over, and joining and cooling under pressure. This study is to present an analysis of the effects of three welding parameters on the joining properties and to develop a better understanding of physical processes involved. Complete studies have been performed on the effect of IR welding parameters, which also performing a morphological evaluation of welds in glass reinforced polyether sulfone PES composites
