7、rds (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standar

8、ds are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by

In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or devi

10、ations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While the

11、AWS administers theprocess and establishes rules to promote fairness in the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments contained in its standards.AWS disclaims liability for any injury to persons or

Such request

19、s should be addressed to the American Welding Society,Attention: Managing Director, Technical Services Division, 550 N.W. LeJeune Road, Miami, FL 33126 (see Annex A).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are of

Gordon was the chair of the D14.6 stan-dard when it was first published in 1981, and the secondedition in 1996. Gordon was a member of the AWS D14GSubcommittee for about 33 years.Gord

26、on Earle Cossaboom, an AWS Life Member, graduatedfrom the Boston Latin School in 1943. He served in the U.S.Army in Europe during WWII, then returned to Bostonwhere he graduated from Northeastern University with a BSin civil engineering. After receiving his BS degree, he studiedat The Ohio State Uni

27、versity where he earned a MS degree inwelding engineering.In 1954, Cossaboom started his career at General ElectricCompany where he worked for several years. Later, heworked with Westinghouse Electric Company, Syosset, NewYork, and with the Eutectic Corporation. With these weldingequipment manufactu

28、rers, he focused on new product devel-opment and participated in the development of CO2welding.In 1967, he joined American Standards Industrial ProductsDivision in Dearborn, Michigan, as manager of engineering.From 1978 to 1986, Cossaboom worked as a welding engineerfor the Manufacturing and Quality

29、 Division of Gilbert Com-monwealth, Jackson, Michigan. From 1986 to his retirementin 1988, he served on the faculty at Ferris State University asan associate professor in the Welding Technology Depart-ment. He was an AWS member for 54 years and an activemember of the Central Michigan Section.Gordon
