Steel-Reinforced Polyethylene Pipe: Extrusion Welding, Investigation, and Mechanical Testing

Abstract: This work presents extrusion welding with a square butt joint of V-shaped steel-reinforced polyethylene (SRPE) corrugated pipe. The SRPE pipe was welded in a single pass on the inside of the pipe. The welding temperature was controlled at 190°–200°C. The welding extruder was modified for controlling the travel speed and preheating conditions for welding. A high-density polyethylene (HDPE) rod was used as the welding filler metal, which was inserted into the extruder with a speed of 2.20 m/min. Welding progress… Show more

“…It could be explained that the CO2 mixed Ar based shielding gasses have a low ionization potential results in improved arc stability, puddle fluidity and eliminated metal spatter [13,16]. The preheating condition could make soften the base material [17] and decreased the heat loss of welding which affected that the welding heat could intensively be introduced into the weld area and increased the weld dilution. Also, the preheating could increase the weld dilution because the cooling rate of welding was slow down [8][9][10]15] and the melting combination of molten weld and base had more time before the solid transformation.…”
