HALF-PRODUCT WITH ELECTRICALLY CONDUCTIVE PLASTIC LAYERS

摘要

A novel method of making a half-finished product is described, in which the welding of electrically conducting and non-conducting plastic layers is achieved by the Joulean heat of an electrically conducting layer after applying a corresponding voltage. The novel method has advantages due to the fact that it dispenses with complex, fault-prone heating devices and can be used within broad limits.
