Abstract

Process for mfg. capacitors using dielectrics which are protected from breakdown. The novelty is the use of a capacitor field onto which >=1 additional field is superimposed so a prescribed part of the lines of force is deflected in another direction and the electrostatic pressure on the dielectric is therefore altered by a prescribed amt. The process is pref. employed for welding the plain surfaces of two metal parts together where the plain surfaces are surrounded by intermediate dielectric layers forming an air tight welding cavity pref. provided with an opening permitting a vacuum to be applied. Pref. vacuum welding devices are included in 30 claims. Used for welding two metal sheets together using a capacitor-discharge pulse welding machine, where the invention permits a redn. in voltage and prevents premature discharge.
