Description
Technical Field
The invention relates to the field of welding engineering, in particular to a friction stir welding real-time temperature measuring device.
Background
Friction Stir Welding (FSW for short) was proposed by the British institute for Welding (TWI) in 1991, month 10. The friction stir welding process is mainly used for welding low-melting-point materials such as aluminum alloy and the like at first, and much research is carried out on TWI (two-way welding) about the characteristics, application and the like of the friction stir welding process.
The friction stir welding technology is a solid phase welding technology, has the advantages of low heat input, high efficiency, energy conservation, high reliability and the like, and is widely applied to the field of aerospace. And in actual processing, because reasons such as work piece machining error, work piece deformation, clamping are improper, the contact condition of stirring instrument and work piece constantly changes during the welding, leads to welding temperature fluctuation, causes welding quality unstable: (1) when the welding temperature is too low, the material is not softened enough, so that the welding defect is easy to generate and the stirring pin is broken; (2) when the welding temperature is too high, defects such as holes and tunnels are easily formed in the joints. Therefore, the stirring tool needs to be subjected to real-time temperature measurement in the welding process, so that the stirring tool can always keep a proper welding temperature, and the welding quality is ensured.
The current friction stir welding temperature measurement technology mainly comprises the following steps: (1) drilling a plurality of small holes on a welding workpiece along a welding seam, embedding a thermocouple for temperature measurement, wherein the workpiece needs to be damaged, the position of the embedded thermocouple is away from the center of the welding seam by a certain distance (generally larger than the diameter of a stirring tool and approximately equal to 2-3 times of welding thickness), otherwise, the thermocouple is stirred into the welding seam, so that the deviation between the measured temperature and the actual temperature of the center of the welding seam is large, the temperature change of discrete points can only be obtained, and the temperature of the center of the welding seam cannot be continuously obtained; (2) the welding temperature is measured by using non-contact temperature measuring devices such as infrared rays and the like, so that a real-time temperature change curve of the central surface of the welding seam can be obtained, but because the methods can only obtain the surface temperature of an object, the deviation between the measured welding seam temperature and the actual central temperature of the welding seam is large.
