A method based on physical indentation pressed continuously into the material under a particular force. The hardness value is derived from energy loss defined by an impact body on a sample.
Also known as bubble leak testing, this method is used to locate leaks in a pressure boundary accomplished by a transparent vacuum box being fixed to the local area with bubble solution. The air inside is evacuated and allowed to stabilize, creating pressure difference. The formation of bubbles signals leaks on the test item.
Concrete Non-Destructive Testing
This is a method of testing that generates information about
the properties of concrete in already existing structures.
The Welders’ Qualification Program, which includes the review and preparation of WPS, witnessing, documentation, testing of coupons, and eventually certification of welders as per ASME, AWS, API and ANSI codes.
