Abstract

Friction stir welding (FSW) have vastly experimented on thermoplastic material due to its wide engineering applications. FSW technique results in the material having low distortion and high joint strength as compared with other joining techniques. The purpose of this paper is to investigate the material flow pattern during FSW on Nylon -6 and conduct assessment on the effect of process parameters in the flow pattern. The method used to detect the material flow is by slotting blue-colored markers along the groove made prior the FSW process. The markers used were Paraffin Wax and blue-coloured Nylon material. Results show that although material flow can be seen, the blue colour makes up almost the entire stir zone. This makes it difficult to see the flow pattern of the blue coloured marker thus further improvements is needed on this technique. It also can be concluded that the material flow is influenced by the pin profile as well as process parameters. This paper shows that at different feed rates, the Nylon material shows different appearance that contributes to different material flow pattern.
