Weldspeconline.com offers a range of welding procedure specifications (WPS) in accordance with the requirements of commonly used welding standards, such as ASME, AWS, ISO, and AS/NZS. The available WPS are either qualified WPS with full test records, prequalified WPS prepared in accordance with applicable prequalification rules, or are additional guidance documents to be used alongside standard welding procedure specifications (SWPS). All WPS have been prepared by an International Welding Engineer with Masters in Welding Engineering and peer-reviewed by International Welding Engineers, all of which have extensive experience in construction and fabrication for the oil & gas, mining, and petrochemical industries.
Simply select the applicable welding standard and then choose your material, welding process(es) and joint type to find a WPS suitable to your needs. Alternatively, click “All Products” or download our WPS register to see a full list of all available WPS.
The ASME IX welding standard is commonly used worldwide for fabrication of pressure retaining components such as pressure vessels, piping, and related auxiliary components. ASME IX allows the use of ‘standard welding procedures’ in accordance with Article V. ‘SWPS’ are previously qualified procedures covering a range of typical processes and joint types.
These WPS are one-page, easy-to-use, shop-floor procedures based on SWPS qualified by the American Welding Society (AWS). These WPS are considered to be ‘additional instructions’ and shall be attached to the AWS SWPS in accordance with ASME IX QW-540(e). The AWS SWPS can be purchased elsewhere online and are not supplied by weldspeconline.com.
These welding procedures are suitable for components designed to ASME VIII (pressure vessel), ASME B31.1 (power piping), ASME B31.3 (process piping), and ASME B31.4 (pipeline systems).
