Abstract

The present invention discloses a connector welding conduction test method and system, which relates to the field of welding conduction test technology, including recording the voltage, current, pressure and duration of welding equipment during welding, calculating the abnormal coefficient of welding process, obtaining the historical welding years, historical welding qualification rate and welding speed of welding operators, calculating the reliability coefficient of welding operators, calculating the risk index of welding operation, and issuing an abnormal warning of connector welding; after receiving the abnormal warning of connector welding at a welding point, obtaining the current and voltage of the welding point to be tested and the current and voltage between the welding point to be tested and the other welding points of the connector, calculating the abnormal conduction coefficient of the welding point to be tested itself and the abnormal conduction coefficient between welding points, and further calculating the conduction index of the welding point to be tested, and issuing an abnormal warning of connector welding conduction. Conducting conduction test analysis when there is a risk in welding operation can avoid unnecessary redundant testing, further saving time and resources.
