How to Reduce Quality Lab Time Associated with a Tube Mill

Written by Cameron Serles on July 30, 2020

Lab time is a precious commodity.  As part of the changeover process on a tube mill, the tube to be produced must first be qualified to a desired level of quality in the lab. This line qualification process often includes cutting as many as three separate cross sections of a tube and sending them to the lab for processing where they get polished and photographed as micrographs. Once created, the micrographs can be measured or analyzed to verify that the weld structure of the tube meets the specifications required by the customer.  By using a weld inspection system that can accurately measure weld bead geometry and tube profiles, it may be possible to reduce the number of micrographs taken for each line qualification from a sample made for 100% of every change over to a lower, statistically relevant percentage.  The net result is that fewer line qualifications are required, leading to fewer tests (e.g., micrograph samples) performed in the lab, saving both lab time and lab personnel costs.
