WELDING ENGINEERING
Welding Preparation and Quality Control occupies a very important place in the manufacture and assembly of industrial facilities and equipment.
All kinds of welded fabrication is done according to a standard. The welding method to be applied must be confirmed according to the relevant standard. Verification of the welding method is done with WPQR. The sample sample prepared according to the standard is welded by a certified welder in accordance with the manufacturing conditions. Destructive and non-destructive tests prescribed by the standard are applied to the prepared sample. If the results of the tests are sufficient, the method is validated.
Welding is a process that must be applied with a specification. All variants of the source should be determined with reference to a previously validated method test (WPQR). The manufacturer makes the welding with the WPS (Welding specification) prepared according to the scope range of the WPQRs in his hands.
In order for your welded productions to be made in accordance with regulations, specifications and Standards, weld conformity tests must be performed at the beginning of production.
