JFE Steel Develops Unique Ultrasonic Testing Robots for Inspecting Steel Plate

02 March 2021 

JFE Steel Corporation announced today that it has developed the world’s first autonomous Ultrasonic Testing Robots (UT-Robots) for inspecting thick steel plate. The company has deployed three of the robots in a steel plate plant in Japan to carry out automated offline UT that are proving to be more reliable and efficient than conventional manual UT.

The robots are now in service at a plant in the company’s Keihin-district operations, which are part of JFE Steel’s multilocation East Japan Works. Additional robots will be deployed at steel-plate plants in the company’s Kurashiki and Fukuyama districts within the multilocation West Japan Works. Going forward, JFE Steel expects the UT-robots to further enhance the quality of its steel plate products and also further streamline production operations.
