The invention provides a high-frequency resistance welding experiment device. The high-frequency resistance welding experiment device mainly comprises a machine tool, a resistance welding machine component, a welding rolling mill component and a welding plate material traction component, wherein the machine tool and a high-frequency power source of the resistance welding machine component are botherected on the ground, the high-frequency power source is connected with a resistance welding machine through a high-frequency power source wire, the resistance welding machine is fixed on the machine tool and is in contact with a welding plate material, the welding plate material is placed inside a welding rolling mill, the welding rolling mill is also fixed on the machine tool, a D-shaped shackle connects the welding plate material with a steel wire rope, the steel wire rope spans a large pulley and a small pulley and is attached to hydraulic equipment finally, the large pulley is fixed ona pulley supporting rack, the pulley supporting rack is fixed on the machine tool, the small pulley and the hydraulic equipment are both fixed to the bottom of the machine tool, and the welding speedis controlled by controlling a speed adjusting valve on the hydraulic equipment. The high-frequency resistance welding experiment device can control the squeeze amount of the plate material in high-frequency resistance welding, can also guarantee the personal safety of experimental personnel and has good welding efficiency.
