This European Standard shall be given the status of a national standard, either by publ
15、ication of an identical text or by endorsement, at the latest by March 2001, and conflicting national standards shall be withdrawn at the latest by March 2001. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, an
16、d supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex 24, which is an integral part of this standard. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement
17、this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European Standard is composed of the following parts: Part 1 : General guid
18、ance for arc welding Part 2: Arc welding of ferritic steels Part 3: Arc welding of stainless steels Part 4: Arc welding of aluminium and aluminium alloys Annexes A and B are informative. Page 4 EN 1 O1 1-4 : 2000 Introduction This European Standard has been issued with several annexes in order to co
19、ver 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 gives general guidance for the satisfactory design, production and control of welding and
20、 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 regardless of the type of fabrication involved, although the application standardkontract may hav
21、e 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 be obtained from the design specification. Informative annexes give information on detrime
22、ntal 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 identifies the main factors that affect the welding of aluminium. This will be influenced b
23、y 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 welds; - temporary attachments; - arcing; - inter-run cleaning and treatment; - welding pro
24、cedures; - identification; - inspection and testing; - quality requirements; - correction of non-conformity; - distortion; - post-weld heat treatment; - abbreviations and symbols; - run-on/ run-off plates. Page 5 EN 1 O1 1-4 : 2000 1 Scope This European Standard gives general recommendations for the
25、 manual, mechanized and automatic fusion welding of wrought and cast aluminium alloys and combinations thereof. For general guidelines, see EN 101 1-1. In this standard the word “pipe“ alone or in combinations is used to mean “tube“ or “hollow section“, although these terms are often used for differ
26、ent categories of product by different industries. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For d
27、ated 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.

40、uality 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, EN 288-4 and prEN IS0 15614-4:2000. 5 Parent metai 5.1 General This standard applies to wrought, cast
41、and combinations of aluminium, e.g. according to EN 287-2, EN 1418, EN 288-4 and prEN IS0 15614-4:2000. The principles of this standard can be applied to other non-standard or proprietary aluminium alloys, which can include-the advanced superplastic alloys and metal matrix composites, provided the c
42、omposition 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 fully take into account welding requirements. For this reason it is sometimes necessary to specify ad
43、ditional requirements for the material when placing the order. This can include selectiodrestriction of compositiodmechanical properties (within certain additional limits to the basic standard requirements) and additional cleanliness of the components. Permanent backing material and temporary attach
44、ments shall be compatible with the parent metal. 5.2 Storage and handling Contact with ferritic materials and copper should be avoided, in order to prevent corrosion. To avoid the use of incorrect materials, they shall be stored so that the alloy type is known (see warning on hard stamping in EN I O
45、 1 1 - 1 ). Page 8 EN 1 O1 1-4 : 2000 6 Factors affecting properties of welded structures and assemblies A short list of possible detrimental effects, which can occur as a result of welding, is given in annex A. The list is not exhaustive but features those metallurgical and technological influences
46、 that are specific to, or more prevalent with, aluminium. Potential causes and counter measures are also listed. Consideration shall be given, e.g. in the design of welded structures, to the mechanical properties of the heat affected zone (HAZ) and the weld deposit which can be influenced by the wel
47、ding procedure. For instance, the weld deposit and the HAZ can have lower mechanical properties than the parent material. Care shall be taken to avoid the creation of any HAZ that has not been considered in the design, e.g. the welding of a temporary attachment. 7 Fusion welding processes This stand
48、ard applies to the following processes according to EN IS0 4063 which may be used singly or in combination: - 131 Metal arc inert gas welding (MIG); - 141 Tungsten inert gas arc welding (TIG); - 15 Plasma arc welding. Other fusion welding processes by agreement. 8 Welding consumables 8.1 Filler meta
49、l Filler metal shall be compatible with the parent metal, see annex B. Filler metals shall be stored in their original packaging in a dry place adequately protected fi-om the effects of the weather and in accordance with relevant standards and/or the suppliers recommendation. Particular attention shall be paid to the storage and identification of partly used reels of wire and packages of rods located in fabricating shops or on site. This is necessary to ensure that they do not become moist or contaminated, e.g. by dust or oil. Page 9 EN 1 O1 1-4 : 2000 8.2 Shie
