Abstract

A method for calculating the conditions of high-frequency (HF) welding of plastics in a working condenser with the non-uniform distribution of the electric field is described. The method determines the instantaneous specific power of the internal heat sources on the basis of capacitance and voltage in the working condenser which is not completely filled with the welded material. An example of calculating the temperature distribution in the thermoplastic material in the process of HF welding of components in equipment with a working condenser of the ‘thin edge against isolated plane’ type is outlined.
