Quality Material Inspection

Quality Material Inspection, known as QMI, is a company in California that does nondestructive testing. This is a way to check parts and materials without damaging them. The company says ultrasonic inspection and eddy current testing have been its main focus since 1981. It works on advanced materials.

QMI also does research, development and prototyping. It builds custom test instruments and scanning systems. The site says the company designs and makes ultrasonic transducers and eddy current probes. It also builds automated inspection systems based on those methods.

In 1995, QMI developed AIRSCAN, an air-coupled ultrasonic method. The site says it avoids contaminating sensitive materials during tests. The company credits its founder, Willem Grandia, with laying the base for its work. It says aerospace firms know it for its fresh approach to testing advanced materials.

The list of ultrasonic methods is long. It includes air-coupled ultrasonics, dry-coupled ultrasonics, water immersion and water squirt methods, and contact methods. Eddy current testing is offered with a focus on low conductivity materials. QMI also tests multi-layer circuit boards for bonding faults and inspects composites.

Clients can have work done at QMI's own site or at the client's location. The company also offers help with applications and consulting. It develops new ultrasonic and eddy current test techniques. This work suits clients with hard inspection problems, since the company says it has access to the latest NDT technology. Its air-coupled scan systems use modern data capture and imaging instruments.

QMI says it has deep experience across aerospace, aircraft, nuclear, petrochemical, construction, pipeline, offshore structure and shipbuilding work. The site lists agents for Europe, India and Korea. These are Imaginos NDT in the United Kingdom, NDT Solutions in India and NDT LAND in Korea. Visitors can ask for a quote through the website. Visitors are welcome to tour the facility if they give notice in advance.

The website has pages for ultrasonic and eddy current testing, Airscan, scanning, systems, approvals, articles, quotes and contact details.
