Abstract
Electrical contact is the execution unit of low-voltage electrical equipment. The welding quality directly determines the service life and reliability of entire electrical equipment. In this paper, resistance welding was used in the welding of DZ-47 electrical contact. The influence of welding current, welding time and electrode pressure on the shear stress of the contact was analyzed. The welding interface morphology and elemental distribution were also studied. The results show that resistance welding is feasible for electrical contact welding under the appropriate processing parametres. It is additionally found thats in the case of same process parameters the interface diffusion layer thickness and the amount of diffusion of elements are not the same due to the electromagnetic force and the unreasonable design of electrical contact.
