EMERSON'S NEW ADVANCED X-RAY SYSTEM IMPROVES PROCESS AVAILABILITY
When a customer or a device manufacturer wants to be absolutely certain that parts and assemblies are welded according to industry best practices or regulatory standards, it is common for the manufacturer to ship the welded device or component to a third-party inspector. While these inspectors follow regulated standards, interpretation of these standards can be subjective, resulting in unreliable quality control. To remove this variability and ensure adherence to standards, Emerson X-rays and inspects its Micro Motion Coriolis meters in its Boulder, Colorado, and Chihuahua, Mexico, manufacturing facilities according to rigorous interpretation of the standards. Both locations have the same equipment and capabilities. Rock Tanner, director of quality and engineering services at Emerson's Micro Motion division, and an ACCP¹ Level III Nondestructive Testing Professional, leads a team of qualified radiographers in the standards assurance procedure. By virtue of these certifications, the Micro Motion Coriolis testing team is qualified to verify the integrity of any type of flowmeter weld. "Customers occasionally order a flowmeter with weld inspection," Tanner states. "By performing this inspection in-house and under qualified supervision, we are able to provide precise data that the device meets domestic and international regulatory requirements. Further, weld inspections give customers peace of mind that a critical process will not fail due to the flowmeter weld." In addition to customer-requested inspections, Emerson performs weld inspections for other purposes to make sure best practices are followed consistently. At least five percent of all Micro Motion flowmeters receive random X-ray weld inspections, ensuring that the expertise of each welder and the quality of all welding equipment is regularly monitored. These random inspections, coupled with those requested by customers, result in the work of each welder (human and machine) being inspected more than once per month. Other duties for the new X-ray system include inspecting incoming welded parts, components, or raw materials if there is any question about the quality of vendor-provided components. The component can be examined closely for flaws or to ascertain component integrity. This commitment to complete product quality, with in-house investment and capability, helps ensure customers receive only the highest quality Micro Motion devices from Emerson, the leader in Coriolis flowmeters.
