Abstract:
This work focused on improving the reliability of the test results through the development of a laser marking system for recording Quick Response Code (QR Code) on specimens through the automatic recognition of samples for product certification tests at Usiminas' mechanical testing laboratory in Ipatinga. The marking was done manually, using industrial markers, which could allow the exchange of samples or specimens, approving unrepresentative tests, rework and decrease of service level agreement. The changes were both on sample receiving and preparing process and on manufacturing execution system (MES) from mechanical and metallographic testing laboratory (LEME). The positives results were traceability ensurement of samples and specimens, increase of productivity, automating and security of the process and, consequently, increase on reliability of tests results. The solution is innovative and scalable.
