Types of polyethylene welds Butt welding: Butt welding is the most common and best Option to connect polyethylene pipes. In this method, the connection surfaces (full thickness of the pipe wall) are heated with a hot plate to the welding temperature. The hot plate is then removed and the molten surfaces are compressed by applying a certain pressure over a period of time and the welding operation is completed. Benefits of butt welding: • Weld integrity across wall surface or pipe thickness • High safety (welding place has higher resistance than pipe) • Protection against corrosion and environmental pollution • Ease and speed of welding operation • Low cost • No leakage • Repeatability of welding parameters • Reduction of human error Electrofusion welding: The electrofusion welding socket connections use heat coils to generate heat and connect the pipes. In this method, only a thin layer of the outer surface of the tube is involved with the electrofusion connection. Therefore, this method is used in more limited applications. Welding quality in both methods depends on the welding machine, the skill and experience of the welder, the optimal use of welding machines and equipment, and welding instructions. Passing welding courses and obtaining a valid and updated certificate is one of the requirements of the welder. The most important methods of thermal connection in polyethylene systems are butt welding and electrofusion welding
