Automated Manufacturing Inspection (AMI)
Newswave November 1999, Volume 2 Issue 4. A Newsletter published by Tektrend Intl Inc.
Typical applications will vary greatly. A few examples are listed below as guides. We should however not constrain ourselves to these applications as we have a strong engineering team that specializes in developing new applications:
|Steel plate - inspection for delamination. An array of transducers is used to inspect the metal for flaws. The transducers are EMATs or contact piezo-electric transducers depending on the application. The number of transducers depends on the size of the flaws, to be detected, the required speed of the inspection and the size of the plates.|
|Bar - inspection. Bars are inspected for forging or cooling cracks. Special transducer shoes are used to ensure that couplant is maintained. The number of transducers is a function to the diameter of the bars.|
Line pipe - inspection for delamination. An array of transducers made to fit a pipe diameter is placed on a pipe to inspect for flaws.
Longitudinal and spiral welds in line pipe-inspection for weld defects. 100% of the weld beam is inspected using transducers at various angles. Automated tracking of the weld position is performed.
Installation These types of systems always require an installation on-site by Tektrend engineering and technical staff. Typical deliveries for AMI systems are 4 to 6 months after receipt of order depending on requirements and complexity. It is often important to identify the windows of opportunities (in terms of plant shutdown or maintenance) to plan our installation around their production schedule.
