چکیده مقاله
In this study, heat assisted friction stir welding HFSW was investigated as a novel method for joining high density polyethylene HDPE sheets, focusing on the effects of two key factors: tool pin profile and the addition of varying percentages of ABS on weld quality and mechanical performance The primary objective was to enhance the mechanical behavior of the joints, including tensile strength and impact resistance, through optimization of the base material composition and the selection of appropriate tool geometry Also, a novel HDPE/ABS polymer blend was prepared, and its performance under HFSW was systematically evaluated Three different tool pin geometries were designed and fabricated, and their influence on material flow, joint quality, and mechanical performance was thoroughly analyzed The results revealed that the incorporation of 5 wt% ABS combined with the use of a simple cylindrical pin tool produced the highest weld quality in terms of both tensile and impact strength These results demonstrate that employing HDPE/ABS blend in conjunction with HFSW provides an effective approach for producing polymer joints with enhanced durability and improved resistance to impact and brittle fracture
