In the calibration control room, pressure gauges, dimension measuring equipment, wattmeter, voltmeter, heat treatment temperature measuring instrument are regularly corrected so that correct measuring can be made.
In the material testing room, tensile test, bending test, hardness test and other tests are carried out with the testing equipment corrected by Japan Marine Affairs Association ( Class NK ) to establish method of welding and to confirm welding quality.
Ultrasonic flaw detection up to 100mm thick stainless steel can be made.
As non-destructive testing in manufacturing processes, RT and/or UT shall be made.
We have X-ray penetrating testing equipment which can test materials up to 150 mm thick.
For confirmation of surface quality, PT, MT and VT shall be carried out.
