Abstract:
To clarify where the exact position of dynamic welding occurrence is, electrical endurance tests are conducted with AgSnO2, AgNi and AgCdO contacts. Waveforms of contact force, displacement, voltage and current are recorded with Labview during tests, which can make it out whether welding occurs during breaking or making operation. The experimental results shows welding may occur in breaking as well as in making operations, possible mechanism for welding in break is discussed.
