methods to measure the temperature of the krimp or schweisszone during the implementation of a warmkrimp - or a punktschweissvorganges.

摘要

The present invention relates to a method for measuring the temperature of the crimping or welding zone during a heat crimping or spot welding operation on one or a plurality of parts, said operation comprising the passage of an electric current through said part or parts in said zone, the current being supplied by means of at least one electrode in electric contact with one of said parts. According to the invention, at least one of the thermoelectric signals respectively generated between one or other part and the electrode with which they are in contact and/or between the parts themselves is used as a measuring signal. The invention also relates to methods for controlling the parameters of a crimping or spot welding operation.
