YU Li1, LIU Zhi-yuan2, WANG Dong2, et al. Review of Welding Phenomena of Vacuum Circuit Breaker Contacts[J]. High voltageapparatus, 2008, (1): 64-68.DOI:
The researches on welding of electrical contacts were summarized
and the factors contributing to welding of contact were cataloged.The quantitative criterion of weldability and the experimental methods for measuring welding force were introduced.According to material characteristics of electrical contact
the weldability of a material strongly depends on its hardness
tensile strength
electric conductivity and thermal conductivity
etc.The experiments can be guided by mathematical model of welding force
because the welding force can be measured directly during the experiments.
