title = "A novel experimental evaluation method of welding characteristics for contact materials",
abstract = "Contact welding failure considerably influences the electrical lifetime and reliability of electromechanical switching devices. Also, the welding characteristics correlate closely with physical properties of contact materials, contact force, current level and duration. In this paper, a novel experimental method for reoccurring the welding phenomenon between two closed contacts is proposed. And the welding force and associated welding trace are measured simultaneously. Furthermore, the effects of current load and static contact force on the welding characteristics of different contact materials (Ag, Cu, AgSnO2 and AgNi) are investigated explicitly. Finally, a modified mathematical model for calculating threshold welding current of elastic contact is proposed.",
