Embodiment Construction
[0024] In order to make the purpose, technical scheme and advantages of the present invention clearer, the accompanying drawings will be used below to detect the residual stress of thin steel welded plates for cruise ships with narrow weld characteristics and the residual stress of the narrow weld surface to the depth of 1mm. The embodiment describes in detail the details of the technical solution of the present invention.
[0025] Such as figure 1 As shown, a method for testing the residual stress of thin steel welded plates with narrow weld features includes the following steps:
[0026] The first step is to use the coercive force method to measure the distribution characteristics of the residual stress of the steel thin welded plate for cruise ships after welding.
[0027] The principle of the coercive force method is to use the magnetic method to measure the residual stress of the material. Under the action of the working load, the ferromagnetic workpiece in the geomagnet...
