Research and Manufacture of Hydraulic Butt Fusion Welding Machine for Different Plastic Material Pipes
Main Article Content
Abstract
This paper introduces the research and manufacture of a hydraulic butt fusion welding machine that permits to weld dissimilar plastic pipes. In welding of dissimilar plastic pipes, the welding parameters at two pipe ends will be different. The butt fusion welding cycle of two dissimilar plastic pipes is established. The fabricated welding machine consists of the following basic components: machine body, two heating plates, four movable clamp rings, hydraulic movement mechanism to move the heater plate, hydraulic system to control the pressure and also to move the pipe ends during welding process. The pressed system has four movable cylinder tubes that move on four fixed pistons. At each side (left and right), a pair of two clamp rings is mounted on two movable cylinder tubes to provide forward and backward movement of a pipe during welding process. Two heater plates heat the two plastic pipe ends at different temperatures depending on the welding temperature of each plastic pipe material. The welding process is built in order to weld two dissimilar plastic pipes. The fabricated hydraulic butt fusion welding machine and the established welding process ensure accuracy and quality for the welding joint of dissimilar plastic pipes.
