Abstract: The sudden outbreak of COVID-19 provide a very favorable opportunity for the development of smart manufacturing. In order to ensure the accuracy, repeatability and traceability of the test results of mechanical properties of steel materials, and improve the labor efficiency, a fully automatic test room for mechanical properties of steel materials is built by using information technology, automation, intelligence and other technologies, which can realize the whole test process unattended. It has become the direction of the future development in the field of steel materials mechanical properties test to build a fully automatic test room for steel materials mechanical properties test.
