In pipeline joints, special controls are required in each flange component to establish a leak-proof connection. A flanged joint is constructed of three distinct yet related parts: flanges, gaskets, and bolts necessary to disassemble a pipeline joint. Breakout flanges are added regularly in specific pipelines where maintenance is frequently required. This research aimed to use (plate with pipes) joint throughout the connecting process to overcome root flaws of aluminum pipes with plate utilizing friction stir welding (FSW) process. The FSW procedure is utilized in the welding process to achieve the welding technique. The material used is aluminum 6082-T6 pipes and plates with an outside diameter of 50 mm and a thickness of 5 mm, with the thickness of the plate being 5 mm by FSW on the face side to the remaining depth of 5 mm. K-110 tool steel was used with 10 mm for shoulder diameter and 3 mm for pin diameter, and 5 mm for pin length. The rotational and traverse speeds are fixed at 1800 rpm and 4 mm/min, respectively. In terms of mechanical qualities, welded (pipes with plate) joints are compared to the base metal. A superior weld strength at FSW for the plate with the pipe of 202 MPa was achieved. |
