| Sinopsis To reinforce the Works, heavy-plate quality assurance System, the existing auton atic ultrasonic test (AUT) system has been recently retrofitted into a fully automated one, followed by the development of a new AUT system for ultra-thick plates, in the Mizushima Works of Kawasaki Steel. All the operations of the AUT system for plates whose thickness range is up to 60mm, such as the setting of testing conditions, testing operation, evaluation, and recording of test results, can be automatically carried out by the digitized devices and a process control computer system. The ultra heavy plate AUT system, which can test plates of over 60mm in thickness, has been developed with emphasis on the automatic recording of test results and the collapsible and portable mechanism that has provided an easier handling of the system. These AUT system have successfully automated the ultrasonic inspection of plates in all thickness ranges, including ultra-thick plates, with very high reliability since their commissioning. |
