There are two types of testing a weldment.

1.) Destructive Testing
2.) Non-destructive Testing

As the word implies, specimens tested by destructive testing, the specimens are destroyed during the test and are worthless after the test. Example of destructive testing are; bent test, tensile test etc

The quality of specimens are tested without destruction. Example of non-destructive testing are; radiographic testing, magnetic particle testing, penetrant testing, ultrasonic testing and eddy current testing

Each method of NDT (Non-destructive Testing) has its own advantages and disadvantages. Choosing the method to be used depends on the data of items to be tested.
