Destructive tests aim to examine the mechanical, chemical, and metallurgical properties of a weldment by breaking, deforming, or chemically processing test specimens removed from a welded joint. These tests are considered to be a direct method of examining the qualities of the weldment.
The destructive tests can be classified into mechanical tests, chemical tests, and structure tests.
The destructive tests are often used to confirm whether or not specific welding procedures can produce the required qualities of the weldment. The following sections outline the major destructive tests.
Destructive tests are as follow –
