Assessment of Polyethylene Welds - Plastics Industry

The two common methods of welding PE pipe are butt fusion and electrofusion (EF). Butt welding has been used successfully in Australia since the 1960s and EF since the early 1980s. These methods are used widely around the world with something in excess of 100,000,000 butt welds and around 20,000,000 EF joints completed annually.
