Scope. The data to support this Standard Welding Procedure Specification (WPS) have been derived from the above listed Procedure Qualification Records (PQRs) which were reviewed and validated under the auspices of the Welding Research Coun- cil. This Standard WPS is not valid using conditions and variables outside the ranges listed. The Ameri- can Welding Society considers that this Standard WPS presents information for producing an accept- able weld using the conditions and variables listed. The user needs a significant knowledge of welding and accepts full responsibility for the performance of the weld and for providing the engineering capability, qualified personnel, and proper equipment to imple- ment this Standard WPS. Application. This Standard WPS is to be used only as permitted by the applicable fabrication docu- ment(s) [such as code, specification, or contract document(s)]. The fabrication document(s) should specifty the engineering requirements such as design, need for heat treatment, fabricating toler- ances, quality control, and examination and tests applicable to the end product. User’s Responsibility. A Standard WPS does not replace or substitute for fabrication codes, specifications, contract requirements, or capability and judg- ment on the part of the user. A Standard WPS is to be used only as permitted by the applicable fabrica- tion code, specification, or contract document. The ability to produce production welds having properties suitable for the application depends upon supplementing the Standard WPS with appropriate performance qualification tests and sound engineer- ing judgment. The user is responsible for the quality and performance of the final product in accordance with the provisions of the fabrication document(s). Supplementary Instructions. To adapt this Stan- dard WPS to a specific application, a user may issue supplementary instructions. Such instructions may consist of tighter fit-up tolerances, higher minimum preheat temperature or any other instructions nec- essary to produce a weldment that meets the requirements of the fabrication document(s). These instructions shall not be less restrictive than pro- vided in the Standard WPS. Safety. Safety precautions shall conform to the lat- est edition of ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, published by the American Welding Society. This specification may involve hazardous mate- rials, operations, and equipment. The specification does not purport to address all of the safety prob- lems associated with its use. It is the responsibility of the user to establish appropriate safety and health practices. The user should determine the applicabil- ity of any regulatory limitations prior to use.The activities of AWS Technical Committees in regard to interpretations, are limited strictly to the interpretation of provisions of standards prepared by the committee or to consideration of revisions to existing provisions on the basis of new data or technology. Neither the committee nor the staff is in a position to offer interpretive or con- sulting services on: (1) specific engineering problems, or (2) requirements of standards applied to fabrications out- side the scope of the document or points not specifically covered by the standard. In such cases, the inquirer should seek assistance from a competent engineer experienced in the particular field of interest.AWS B2.1-8-215  pdf download.
