7、nce with the rules of theAmerican National Standards Institute (ANSI). When AWS standards are either incorporated in, or made part of,documents that are included in federal or state laws and regulations, or the regulations of other governmental bodies,their provisions carry the full legal authority
8、of the statute. In such cases, any changes in those AWS standards must beapproved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or other document that inv
9、okes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.International Standard Book Number: 0-87171-736-0American Welding Society, 550 N.W.

This specification applies to the welding of allprincipal structural weldments and all primary weldsused in the manufacture of cranes for industri
42、al, mill,power house, and nuclear facilities. Furthermore, thespecification applies to other overhead material handlingmachinery and equipment that support and transportloads within the design rating, vertically or horizontally,during normal operations, and, when agreed uponbetween the Owner and Man
43、ufacturer, to loading causedby abnormal operations or environmental events, such asseismic loading.Secondary welds that will be subjected to tensilestresses of less than 5000 psi 34.5 MPa need only meetthe requirements of Section 7, Workmanship, and Sec-tion 10, Weld Quality and Inspection. The engi
44、neeringdrawings shall specify the joint detail, type, and size ofweld. This specification is not intended for application toconstruction- or crawler-type cranes. For the welding ofrails, refer to AWS D15.2, Recommended Practice forthe Welding of Rails and Related Rail Components forUse by Rail Vehic
45、les.All provisions of this specification are equally appli-cable to the strengthening and repairing of existingoverhead cranes and material handling equipment asdescribed above.This specification makes use of both U.S. CustomaryUnits and the International System of Units (SI). Themeasurements may no
46、t be exact equivalents; thereforeeach system shall be used independently of the otherwithout combining in any way. The specification withthe designation D14.1 uses U.S. Customary Units. Thespecification D14.1M uses SI Units. The latter are shownin appropriate columns in tables and figures or withinb
47、rackets . Detailed dimensions on figures are ininches. A separate tabular form that relates the U.S.Customary Units with SI Units may be used in tables andfigures.Safety and health issues and concerns are beyond thescope of this standard, and therefore are not fullyaddressed herein. Safety and healt
48、h information is avail-able from other sources, including, but not limited to,ANSI Z49.1, Safety in Welding, Cutting, and Allied Pro-cesses and applicable federal and state regulations. Someother sources of safety and health information can befound in Annex D.1.2 General Provisions. The Manufacturer
49、s1adherenceto this specification shall include responsibility for thefollowing:(1) Welding, as defined in the Scope, in accordancewith this specification;(2) Producing the welds designated on the drawingsby appropriate welding symbols and notes containingsufficient detail to show joint preparations compatiblewith the designated welding processes;(3) Providing written welding proc
