Dutest also verifies load monitoring equipment and undertakes other non- destructive and destructive inspection work which includes welding inspection.

Initial testing and proof loading

Initial testing of lifting equipment and machinery is extremely important. This testing method ensures that the machinery is used for a long period of time in an efficient manner. All these services of proof loading and initial testing can easily be undertaken at the client premises itself. Some testing methods have been explained as below:

1. The dry penetrant testing

This testing method is used for detection of surface flaws. This is done by using a developer and a chemical ink. It is also mainly used for the non- ferrous metal products as well as gear teeth in which other methods cannot be practiced.

2. The magnetic particle testing

This testing method is used for detecting flaws as well as cracks in welds. This is made of ferrous material, and it is much often incorporated in routing overload testing and a proof load of lifting equipment and plant. For this to be effective, the surface preparation needs to be removed both on the weld and the zone on each side.

3. Thickness gauging

This method is used for measuring internal corrosion. This, in turn, allows various corrosion checks such as tanks, pressure cylinders, pipe work and tanks. This is a technique that is suitable for checking an equipment without having to open and enter that particular area that essentially requires checking. This can also be done without removal of the external coating as it is very convenient.

4. Welding inspection method

A weld can be defined as a fusion of metals. For this purpose, it has to be inspected with the help of personnel who are certified for welding inspection.

There are various parameters that are used by Dutest for operator competency. All these testing and inspection methods are adopted by the company for superior quality of lifting equipment and machinery.
