| Abstract: | Metal magnetic memory ( MMM ) testing technology is a new nondestructive testing method. In order to apply MMM technology to the engineering practice of residual stress testing , this paper designed the software analysis system and portable hardware system of welded joints residual stress testing , which is based on object-oriented programming. The system can realize the welded joint residual stress testing at workshop , which can output data to a computer for further analysis and evaluation. According to the trend analysis of the MMM characteristic , the distribution of the welded joint residual stress can be acquired. The field testing results of pressure vessel ’ s welded joints showed that MMM data are consistent with the X-ray examination , which has proved the accuracy of MMM testing. |
