Abstract

The invention relates to the technical field of resistance welding, in particular to a dissimilar material connecting device based on multi-leg connectors, including: a power supply, an upper electrode, multi-leg connectors, an upper sample, a lower sample and a lower electrode. One end of the power supply is connected to the upper electrode, and the upper electrode is set above the lower electrode; the upper sample and the lower sample are set between the upper electrode and the lower electrode, the upper sample is attached to the lower sample, and the lower sample is connected to the lower electrode. Fitting; the lower electrode is connected to the other end of the power supply. The multi-leg connector is arranged between the upper electrode and the upper sample, the upper part of the multi-leg connector abuts against the upper electrode, and the foot of the multi-leg connector abuts against the upper sample. The dissimilar material connection device based on multi-legged connectors provided by the embodiment of the present invention solves the problem of large differences in physical and chemical properties between different materials, easy chemical reactions to form brittle phases, and insufficient connection strength; the multi-legged connectors can Significantly improve the positive tension performance and torsion resistance of the joint.

Description

technical field [0001] The invention relates to the technical field of resistance welding, in particular to a connection device for dissimilar materials based on multi-leg connectors. Background technique [0002] Resistance spot welding is an important method of joining materials and is widely used in industries such as automotive. The welding process is realized under the action of pressure. When welding, external force must be relied on to make the workpieces to be welded in close contact. The welding current releases resistance heat through the workpieces to achieve welding. [0003] In traditional resistance spot welding, the upper sample and the lower sample are usually placed between the upper electrode and the lower electrode of the resistance spot welding equipment, wherein the upper electrode and the lower electrode are respectively connected to the power supply through conductors. By applying pressure between the upper electrode and the lower electrode, the upper...
