The American Welding Society's Board of Directors has decided that ANSI Z49.1 should be distributed freely, as it is an important voluntary welding safety and health standards document. It is accessible via complimentary electronic distribution.
This document provides the AWS base metal grouping for welding procedure and performance qualification and is identical to the base metal grouping annex found in the latest version of AWS B2.1/B2.1M. Print copies are available for purchase at pubs.aws.org
Use of Forms
For joint details on the WPS, a sketch or a reference to the applicable prequalified joint detail may be used (e.g., B-U4a).
The WPS forms contain lines for inclusion of information that may not be required by the code; these lines need not be completed in order to comply with code requirements.
It is recommended that the qualification and NDT information required by this code be recorded on these forms or similar forms which have been prepared by the user. Variations of these forms to suit the user’s needs are permitted.
M2 is sufficient for the purpose of documenting prequalified WPSs.
WPSs Qualified by Testing
The WPS may be qualified by testing in conformance with the provisions of Clause 4. In this case, a supporting PQR is required in addition to the WPS. For the WPS, state the allowed ranges qualified by testing or state the appropriate tolerances on essential variable (e.g., 250 amps ± 10%).
For the PQR, the actual joint details and the values of essential variables used in the testing should be recorded. An example of a completed PQR form is provided for guidance in filling out the form. A copy of the Mill Test Report for the material tested should be attached. Also, Testing Laboratory Data Reports may also be included as backup information or a PQR Test Result Form. Cross references to the required mechanical tests as applicable to the WPS being qualified are provided on the form for ready reference. Note that not all tests referenced are required.
