DIN EN 1011-1:2009-07 EN 1011-1:2009 (E) 4 Introduction EN 1011 is issued in several parts in order that it may cover the different types of weldable metallic materials and sp

22、ecific welding processes. This part of EN 1011 deals with the production and control of arc welding of metallic materials and is appropriate for all types of fabrication. Specific materials advice is covered by parts 2, 3, 4, 5 and 8. Parts 6 and 7 refer to laser and electron beam welding and each c

23、over a range of materials. 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 may be obtained from the relevant application standard or design specification. It has been assum

24、ed in the drafting of this standard that the execution of its provisions is entrusted to appropriately qualified, trained and experienced personnel. 1 Scope This European Standard contains general guidance for the arc welding of metallic materials in all forms of product (e.g. cast, wrought, extrude

25、d, forged). The processes and techniques referred to in this Part of EN 1011 may not all be relevant to all materials. Additional information relevant to specific materials is given in the relevant Parts of the Standard. 2 Normative references The following referenced documents are indispensable for
