“It costs approximately 1 to 1.5 million dollars a day when a plant is down and not operating, so we have to be very efficient. When you go to the manufacturer, it takes much longer to get a good certified material test report (CMTR) so it’s important to get the correct materials the first time. We use Weldstar for the service and they take the time to do the job right the first time.”
