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 specific 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 cover 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 assumed in the drafting of this standard that the execution of its provisions is entrusted to appropriately qualified, trained and experienced personnel.

EN 1011-1:2009 (E) 6 4 Principles 4.1 General If the manufacturer is recommended to use a control system, the requirement should be in accordance with the appropriate part of EN ISO 3834. 4.2 Fundamental information for fabrication Before the start of fabrication, the customer shall inform the manufacturer of all the information, which is important to the manufacturing process, the operational loading and the envisaged service life of the end product. If no quality requirements are defined, the limiting values for imperfections shall be as stated in the relevant specification. Such information should comprise, for example: 1) Application standard and any additional requirements such as technical rules, guidelines, and statutory requirements. 2) Any specific requirements for welding production, testing and heat treatment. 3) Production (detail) drawings with information relating to dimensions and weld forms, if documents from the manufacturer are not viewed as adequate by the customer or regulatory authority. 4) Qualification requirements for welding, welding related and NDE personnel
5) Methods of welding and testing. 6)
Requirements relating to the selection, identification and traceability of material and personnel, if required. 7) Requirements on machining and surface finish. 4.3 Non-conformance and corrective actions Where applicable, the method and extent of recording non-conformance has to be specified. Before the start of fabrication, the procedure and the methods for rectifying deficiencies, for compensating for distortion and for correcting weld defects are to be defined. 5 Requirements on welding production 5.1 Equipment and devices The manufacturer shall have adequate equipment and resources for meeting the requirements of the contract. All the welding related equipment shall be matched to the respective welding process, the working task and the design of the final product. All electrical equipment which is used in connection with the welding operation shall be installed and used in accordance with IEC/TS 62081 and local regulations. Devices for measuring the welding parameters, such as arc voltage, welding current, wire feed rate, travel speed and shielding/purging gas flow rates, and also for monitoring the preheat and interpass temperatures, shall be available either as part of the welding apparatus or by providing portable equipment.
