Ultrasonic testers boost welding quality, productivity

Article Abstract:

John Deere Dubuque Works uses Panametrics Inc.'s Epoch II and Epoch IIB ultrasonic flaw detectors to detect weldment discontinuities in their construction equipment products. Before acquiring these instruments, the company relied solely on after-the-fact inspection practices, which proved to be inaccurate and harmful to employee morale. After the company' welders began using the testers, however, officials observed a marked improvement in the quality of manufactured parts and in their employees' skills.

Environment makes or breaks the M-60's accuracy

Article Abstract:

The M-60 coordinate-measuring machine (CMM) of the Energy Dept.'s Y-12 Plant in the Oak Ridge Complex is the most advanced machine of its kind due to the precautions and safeguards taken by its operators to ensure that the environment surrounding the machine and its measurement activities are kept constant. Engineers have taken many precautions to ensure that thermal stability and uniformity is present around the machine and its measurement activities.
