Abstract

The invention provides a resistance spot welding auxiliary electrode. The resistance spot welding auxiliary electrode comprises a plate-shaped electrode body and a handle connected with the plate-shaped electrode body, and the two faces of the plate-shaped electrode body are each of a spherical surface structure. The resistance spot welding auxiliary electrode has the beneficial effects that a spherical electrode tip enables the contact adaptability of a product in a welding area and the electrode to be strong, the operation difficulty is reduced, the product quality is ensured, and repair caused by the fact that the quality of a welding joint does not meet related requirements is avoided.

Description

technical field [0001] The disclosure belongs to the technical field of resistance spot welding, and in particular relates to an auxiliary electrode for resistance spot welding. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Due to the physical characteristics of stainless steel such as large thermal expansion coefficient, low thermal conductivity and high resistivity, the welding of stainless steel car bodies in the rail transit industry is mainly based on resistance spot welding and supplemented by arc welding. Most of the stainless steel car body products are non-painted structures, so there are high requirements for the commercial quality of product appearance, such as indentation depth and roundness of solder joints. [0004] The inventors found that when traditional resistance spot welding electrodes are used for welding, for curv...
