Welding Examination

Welding of structures is utilised in a wide range of industries from transportion through to petrochemical plants.  Many of these welds involve alloy steels as well as other non-ferrous metals with special properties suited to the application.  The welds may be simple or complex, requiring the development of weld procedures that ensures the metals properties are not significantly compromised by the welding process.  Welders who create these welds need to be trained and evaluated to ensure the integrity of the weld process.  In both cases weld samples are required to be produced.  ATTAR provides a number of weld examination and testing services for evaluation of the weld procedure and welder qualification.

Available srvices
- Weld macro testing to Australian Standards.
- Sample preparation and identification of microstructures.
- Weld procedure and specification development.
