Description

technical field [0001] The invention relates to a detection device for a friction welding gas valve, in particular to a detection device for testing the weld seam strength of a bimetal material friction welding gas valve, which belongs to the field of detection equipment. Background technique [0002] The gas valve of internal combustion engine is a fragile and high-risk product in the internal combustion engine. If the welding quality of the friction welding gas valve made of bimetallic material cannot be guaranteed 100%, it will increase the danger of high-risk products. Once the gas valve breaks due to welding quality problems, it will cause immeasurable destructive losses in the internal combustion engine cylinder. Therefore, the friction welding quality of this part is required to be 100% reliable, and its quality detection is essential. At present, there are two routine detection methods for the weld quality of friction welding of bimetallic materials as follows: [...

Problems solved by technology

Among them, ultrasonic flaw detection cannot truly reflect the subtle defects of the weld. Although no internal defects are found on the weld, it cannot reflect whether the welding strength of the weld meets the quality requirements, and the detection of the mechanical tensile strength of the weld can It reflects the strength performance of the weld, but it can only be applied to the random inspection method, and cannot achieve the quality inspection goal of 100% inspection

[0005] Since the current detection methods cannot guarantee 100% that the yield strength of the bimetal material friction welding gas valve weld reaches the quality standard, it seriously hinders the wide application of friction welding, a high-quality, high-efficiency, energy-saving and environmentally friendly welding technology on internal combustion engine gas valves. application
