Abstract
An arrangement for welding together molded members consisting essentially of thermoplastic materials having abutting surfaces which extend generally parallel to each other at which a welding connection is made by electrical heat conductors located at the abutting surfaces. The electrical heat conductors are electrically activated to effect a welding operation and at least a plurality of the electrical heat conductors are connected in parallel with each other and are located between the abutting surfaces at which the weld is to be formed.
