چکیده مقاله
There are different joining processes for thermoplastic composites Friction stir spot welding by using two stage refilling process has been introduced recently In this paper, the feasibility of performing this process on polyethylene sheets is studied Also, the effects of the main weldingparameters including the tool rotational speed and the refilling time on the welding strength were investigated using the response surface method RSM The results confirm that this process is applicable on polymer sheets It is concluded that the tool rotational speed is the mostinfluential parameter, then followed by refilling time The results also indicate that the increase of the tool rotational speed results in the reduction of the joint strength, and the decrease of the refilling time increases the welding strength The best obtained strength proposed by theresponse surface optimizer was 798 MPa, which was obtained with tool rotational speed of 1200 rpm and refilling time of 19 82 s
