  • Butt Welding - an overview

    In Handbook of Plastics Joining (Second Edition), 2009. 30.6.1 Heated Tool Welding. PEX (form: pipe). For butt welding of PE-Xa (peroxide cross-linked) to PE-HD pipes, internal stresses caused during manufacture are released when the pipe ends are heated and this can cause problems for the butt welding of PE-X pipes. The dip of the pipe ends leads to a circular groove at the joint, …
