35、fication. EN ISO 25239-4:2011 (E) DIN EN ISO 25239-4:2012-03 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 obtained by the melting of parent material and usual

36、ly 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 this International Standard in order to ensure that

37、 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 commercial applications for FSW involved aluminium. Examples

38、 include railway carriages, consumer products, food processing equipment, aerospace structures, and marine vessels. To parts of this International Standard are listed in the foreword. Part 1 defines terms specific to FSW. Part 2 specifies design requirements for FSW joints in aluminium. Part 3 speci

39、fies 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 (WPS) is needed to provide a basis for planning welding operations

40、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 with written procedure specifications. Metallurgical deviations const

41、itute 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 procedure prior to the release of the WPS to actual production. This part

42、of ISO 25239 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 does not assign those requirements to any specific prod

43、uct 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 inspection. For example, poor design can create serious and co

44、stly 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 fabrication of a quality product, management should underst

45、and the sources of potential trouble and introduce appropriate quality and inspection procedures. Supervision should be implemented to ensure that the specified quality is achieved. The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that complianc

46、e with this document may involve the use of patents concerning friction stir welding given in Clauses 5 to 7.
