Why should I monitor workpiece thickness?
ANS. A weld schedule is developed for a particular material and combination workpiece thickness. Using the wrong parts for a particular welding job, extreme mill variation, improper parts fit-up, or foreign substances on the workpiece can cause variations in workpiece thickness. Any of these variations can affect weld quality, so monitoring workpiece thickness reduces the risk of poor quality welds due to workpiece problems that could escape detection by the operation.
