Abstract
Abstract A method of and apparatus for the manufacture of an electrowelding component of synthetic material comprising a resistance element, in which in a first process phase the component is formed and in a second process phase the resistance element is fixed in place, the adhesion between component and element being achieved by heating the element by electrical energy.
