Resistance welding process, especially for aluminum sheets, comprises welding electrode d.c. polarity reversal, depending on welding parameters measured during welding

摘要

A resistance welding process involves reversing welding electrode d.c. polarity, depending on a welding parameter measured during welding. A resistance welding process comprises generating a welding a.c. by polarity reversal of d.c. applied to the welding electrodes in dependence on one or more welding parameters measured during welding. An Independent claim is also included for resistance welding equipment, especially for carrying out the above process.
