Abstract

The development of magnetic particle inspection testing is not only focused on testing materials placed indoors, where the need for electrical resources is the main thing. The increasing number of requests to carry out Non-Destructive Test (NDT) testing with the magnetic particle inspection method makes inspectors unable to speculate whether in open areas such as mining areas there is a power source available. To reduce the speculation of inspectors about the limited electrical resources in the open area, a permanent magnetic yoke was designed. Permanent magnetic yoke is an NDT testing tool with a magnetic particle inspection method that does not use an electric power source but uses permanent magnets. Yoke material used is Al6061 with a thickness of 50mm. The magnet used is a Neodymium type permanent magnet. The working principle of a permanent magnetic yoke uses the properties of permanent magnetism with the magnetic particle inspection method in areas where there is no power source Based on the results of the comparison test between Permanent Magnetic Yoke and DC Yoke through the same treatment, the level of accuracy of reading subsurface defects on welding joints of steel material with dimensions of 300 x 150 x 10 mm with 3G position SMAW welding process using permanent magnetic yoke is 96.78%.
