Verification of Equipment for Measurements of Resistance Welding Parameters - Standard Requirements and Testing Equipment

The article discusses parameters affecting the resistance welding parameters as well as the methods and equipment used to measure such parameters. The verification of actual welding parameters involves the use of portable meters, measurement systems or monitoring systems, which, in accordance with related standards, should be periodically verified for the accuracy of indications. The accuracy of indications can be verified using a dedicated test rig, developed and made at the Łukasiewicz Research Network – Institute of Welding, enabling simultaneous checks of root-mean-square welding current, current flow time and electrode force. The article also describes the general design of the test rig, its crucial elements as well as software applied when checking equipment. In addition, the article presents test rig accuracy in relation to measurements concerning both welding current and electrode force.
