Welding Procedure Specification
Dueto huge number of variables involved, multifactored knowledge of materials engineering, designs complexities, fluids engineering and regulatory requirements may be critical in addition to the skill of the welder.
Welding Procedure Specification (WPS) is a required document for all code welding. The WPS outlines required parameters to perform welding operations.
The WPS is the step-by-step guide for the welders, fabricators, facilities and pipeline constructors
Other Services
- Welding Procedure Specification (WPS)
- Welding Procedure Qualification Record (WPQR)
- Welder Performance Qualification (WPQ)
Our WPS details welding process with procedural steps, the base materials specifications, the joint design and geometry, gases and flow rates, welding position and includes all relevant process conditions and variables.
We also prepare testing requirements as per specified by the code and regulator and equipment type. These include both destructive and non-destructive testing.
We follow formats as specified by the code
We prepare the Welding Procedure Qualification Record that qualifies the Welding Procedure Specification.
As part of WPQR we support our clients with:
- Welded procedure qualification plates compliance to qualify WPS,
- Test parameters recording at the time of welding to ensure compliance to WPS,
- Supporting documentation, such as material specifications, electrode specifications and shielding gas specifications, as part of the WPQR,
- Recoding all required testing, both non-destructive and destructive. These tests may include X-Ray examinations, ultrasonic examinations, tensile testing, bend testing and when required impact testing.
We also help our clients to secure Regulatory Certification by combining WPQR information with that of the WPS.
WPQ is required by all codes for all welders and if required, Northern Crescent supports its clients by delivering:
- Documented track of WPS with reference to the qualification test to identify the welder by name and/or clock number,
- List of essential parameters applied during the test reports the results of the required qualification tests,
- Specific qualified limits for welder (as for most codes there is a time limit associated with the welder qualification test).
