[0002] Aircraft sheet metal welding welds are a crucial part of aircraft manufacturing and maintenance. In aircraft structures, the welding quality of sheet metal parts is directly related to the safety and reliability of the aircraft. Welds need to have high strength, good sealing and fatigue resistance. During the welding process, welding parameters such as current, voltage, welding speed, etc. must be strictly controlled to ensure the stability of the weld quality. In order to detect the quality of the weld, a variety of non-destructive testing methods are usually used, such as ultrasonic testing, X-ray testing, etc., so it is necessary to use detection probes to detect metals and metal welds.
