This specification applies to all structural welds used in themanufacture and repair of earthmoving, construction, andagricultural equipment.1 It reflects the weldingpractices employed by manufacturers within the industry andincorporates various methods which have been proven successful byindividual manufacturers. No restrictions are placed on the use ofany welding process or procedure, provided the weld produced meetsthe qualification requirements of this specification. No attempt ismade to limit or restrict the welding technology progression ofearthmoving, construction, and/or agricultural equipmentmanufacturing and repair, nor should any such limitation beinferred. Design criteria for allowable stresses for the base andweld metal and the fatigue analysis for welded joints are notpublished in the specification. The user shall utilize AWS D14.4,Specification for Welded Joints in Machinery andEquipment, or appropriate engineering practices and principlesfor design criteria.
The Manufacturer’s adherence to this specification shall includeresponsibility for the following:
(1) welding, as defined in 1.1.1, in accordance with thisspecification;
(2) producing welds as designated on drawings by appropriatesymbols and notes, with sufficient detail to show joint preparationcompatible with applied processes;
(3) providing and using written welding procedure specifications(WPSs);
(4) ensuring that qualified welders are used to make welds;
(5) recording and maintaining results of all welder performanceand procedure qualification tests;
(6) controlling use of designated base metals andconsumables;
(7) inspecting the welds to the requirements of thisspecification;
(8) ensuring a safe welding environment and safe weldingpractice;
(9) having a quality system in place. The requirements of AWSB5.17, Specification for the Qualification of WeldingFabricators may be used as a guide in establishing thisquality program. Accreditation of quality systems of weldingfabricators may be obtained through the AWS Certified WeldingFabricator (CWF) or equivalent programs.
1 For purposes of this specification, earthmoving,construction, and agricultural equipment are described asself-propelled, on and off-highway machinery and associatedimplements. Such products as crawlers, tractors, graders, loaders,off-highway trucks, power shovels, backhoes, mobile cranes,draglines, and similar equipment are considered to be included inthis specification.
