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: [...
