EN ISO 25239-5:2011 (E) DIN EN ISO 25239-5:2012-03 3 Introduction Welding processes are widely used in the fabrication of engineered structures. During the second half of the twentieth century, fusion welding processes, wherein fusion is
28、obtained by the melting of parent material and usually a filler metal, dominated the welding of large structures. Then, in 1991, Wayne Thomas at TWI invented friction stir welding (FSW), which is carried out entirely in the solid phase (no melting). The increasing use of FSW has created the need for
29、 this International Standard in order to ensure that welding is carried out in the most effective way and that appropriate control is exercised over all aspects of the operation. This International Standard focuses on the FSW of aluminium because, at the time of publication, the majority of commerci
30、al applications for FSW involved aluminium. Examples include railway carriages, consumer products, food processing equipment, aerospace structures, and marine vessels. The parts of this International Standard are listed in the foreword. Part 1 defines terms specific to FSW. Part 2 specifies design r
31、equirements for friction stir weld joints in aluminium. Part 3 specifies requirements for the qualification of an operator for the FSW of aluminium. Part 4 specifies requirements for the specification and qualification of welding procedures for the FSW of aluminium. A welding procedure specification
32、 (WPS) is needed to provide a basis for planning welding operations and for quality control during welding. Welding is considered a special process in the terminology of standards for quality systems. Standards for quality systems usually require that special processes be carried out in accordance w
33、ith written procedure specifications. Metallurgical deviations constitute a special problem. Because non-destructive testing of the mechanical properties is impossible at the present level of technology, this has resulted in the establishment of a set of rules for qualification of the welding proced
34、ure prior to the release of the WPS to actual production. ISO 25239-4 defines these rules. Part 5 specifies a method for determining the capability of a manufacturer to use the FSW process for the production of aluminium products of the specified quality. It defines specific quality requirements but
35、 does not assign those requirements to any specific product group. To be effective, welded structures should be free from serious problems in production and in service. To achieve that goal, it is necessary to provide controls from the design phase through material selection, fabrication, and inspec
36、tion. For example, poor design can create serious and costly difficulties in the workshop, on site, or in service. Incorrect material selection can result in welding problems, such as cracking. Welding procedures have to be correctly formulated and qualified to avoid imperfections. To ensure the fab
37、rication of a quality product, management should understand the sources of potential trouble and introduce appropriate quality and inspection procedures. Supervision should be implemented to ensure that the specified quality is achieved. EN ISO 25239-5:2011 (E) DIN EN ISO 25239-5:2012-03 41 Scope Th
38、is part of ISO 25239 specifies a method for determining the capability of a manufacturer to use the friction stir welding (FSW) process for the production of products of the specified quality. It specifies quality requirements, but does not assign those requirements to any specific product group. In
39、 this part of ISO 25239, the term “aluminium” refers to aluminium and its alloys. This part of ISO 25239 does not apply to friction stir spot welding. 2 Normative references The following referenced documents are indispensable for the application of this document.
