POSSIBILITIES OF TECHNICAL PROCEDURE CREATION FOR TESTING THE WELD JOINT BY A NON-DESTRUCTIVE METHOD

Abstract

The continuous increasing of requirements for product quality leads to increased flaw control and evaluation. One of the inspected parts of the product is a welded joint. The flaws should be eliminated as far as possible to avoid the failure or destruction of the product. In the field of weld inspection, there is the most used the non-destructive testing, whose main advantage is that the product remains unchanged for further use after testing. The presented article is focused on the possibilities of technical procedure creation of weld inspection by use of non-destructive testing. The introduction part of this article describes a theoretical approach to non-destructive testing, concretely the ultrasonic testing with the consequent description of materials and methods which were used to create the technical procedure. The main part of the article describes the possibilities of creating the technical procedure for a concrete practical example and it provides a general evaluation of the proposed solution at the end.
Key words: technical procedure, welding, non-destructive testing.
