Supporting your Quality System - Welder Operator Testing
As part of our commitment to quality management, Thistle Fabrication offers clients a complete Welder Operator Testing service in accordance with specific weld procedures.
Organisations can send their welders to our Kwinana facility, where we arrange testing and qualification to meet any required Welder Qualification standards. Qualifications are issued following NDT testing or, where required, mechanical testing, all carried out by NATA-accredited laboratories.
We also provide engineering organisations with full support in the development and qualification of weld procedures.
If you have welders requiring testing against a single procedure or multiple procedures, contact us at info@thistlefab.com.au. Our clean, well-equipped facilities ensure efficient testing, and results are reported promptly.
We offer Weld Procedure Qualifications and Welder Operator Qualifications to the following standards:
ASME IX
AS 3992
AS 2885.1
AWS D1.1
AS 1554.1
Ask for Michael or John to discuss your welder qualification needs and find the right solution for your requirements.
