TYPES OF TESTING


There are two types of testing a weldment.

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

DESTRUCIVE 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

NON-DESTRUCTIVE TESTING
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.
