25、4 Introduction This European Standard has been issued with several annexes in order to cover aluminium and the different types of its alloys in all forms which will be produced to the relevant European standards. In this standard the term aluminium stands for aluminium and its alloys. This standard
26、gives general guidance for the satisfactory design, production and control of welding and details the possible detrimental effects which may occur, together with advice on methods by which they may be avoided. Generally it is applicable to all types of aluminium materials and is appropriate regardle
27、ss of the type of fabrication involved, although the application standard/contract may have additional requirements. Permissible design stresses in welds, methods of testing and acceptance levels are not included because they depend on the service conditions of the fabrication. These details should
28、be obtained from the design specification. Informative annexes give information on detrimental effects (see annex A) and choice of consumables (see annex B). This document details only welding related matters and does not give any details of mechanical properties of the welded joint. This standard i
29、dentifies the main factors that affect the welding of aluminium. This will be influenced by parent metal, consumables, design, welding procedure, welding equipment, joint preparation etc. General requirements for fusion welding of metallic materials are detailed in EN 1011-1, in particular: - tack w
30、elds; - temporary attachments; - arcing; - inter-run cleaning and treatment; - welding procedures; - identification; - inspection and testing; - quality requirements; - correction of non-conformity; - distortion; - post-weld heat treatment; - abbreviations and symbols; - run-on/ run-off plates.

31、 5 EN 1011-4:2000 BSI 26 January 2004 1 Scope This European Standard gives general recommendations for the manual, mechanized and automatic fusion welding of wrought and cast aluminium alloys and combinations thereof. For general guidelines, see EN 1011-1. In this standard the word “pipe“ alone or i
32、n combinations is used to mean “tube“ or “hollow section“, although these terms are often used for different categories of product by different industries. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative re
33、ferences are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

46、he purposes of this European Standard, the terms and definitions in EN 1011-1 apply. 4 Provision of quality requirements To ensure the quality of work it shall be performed by approved personnel in accordance with e.g. EN 287-2, EN 1418 and EN 719 using approved procedures e.g. EN 288-1, EN 288-2, E

The principles of this standard can be applied to other non-standard or proprietary aluminium a
48、lloys, which can include the advanced superplastic alloys and metal matrix composites, provided the composition of the alloy falls within the parent metal groups listed in annex B. In such cases the use of this standard shall be in accordance with the design specification. Material standards do not
49、fully take into account welding requirements. For this reason it is sometimes necessary to specify additional requirements for the material when placing the order. This can include selection/restriction of composition/mechanical properties (within certain additional limits to the basic standard requirements) and additional cleanliness of the components. Permanent backing material and temporary attachments shall be compatible with the parent metal. 5.2 Storage and handling
