The paper focuses on the problems of monitoring the resistance spot welding process of thin metal sheets used in aircraft structures. The welding process is conducted using welders with software control which allows the welding cycle to be established. Essential parameters in the welding process include: electrode profiles, establishing electrode force as well as the shape and the intensity of the current heating the weld. The paper proposes using a measurement system which registers the above-mentioned welding process parameters and utilises the modules of data acquisition, series NI 9215 operating in a set with NI cDAQ-9178. Software which uses the LabVIEW environment was implemented into the measurement system. The measurement of the welding current intensity was made using a Rogowski coil, while other measurement signals were obtained from the diagnostic interface of the programmable controller of the welder. The paper presents preliminary results of the research. The objective of the initial research is the preparation of a calibration method of welder measurement systems.
