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.
Claims6
In an arrangement for welding together molded members consisting essentially of thermoplastic material, said molded members being shaped to define abutting surfaces extending generally parallel to each other at which a welding connection is made by means of electrical heat conductors located at said abutting surfaces, said heat conductors being adapted to be electrically activated to effect a welding operation, the improvement comprising that at least a plurality of said electrical heat conductors are connected in parallel with each other and are located between said abutting surfaces.
