The first ediion of the Codle for Fusion Welding and Ges Cating in Bailding Consractio was published by the American Welding Society in 1928 and called Code 1 Part A. It was revised in 1930 and 1937 under the same title. It was revised again in 1941 and given the designation D1.0. D1.0 was revised again in 1946, 1963, 1966, and 1969.

The code was bined with D2.0, Specijicatioresx for Welding Hig/nuy and Raihy Bridges, in 1972, given the designation D1.1, and retitled AWS Srnacnraf Weling Code. D1.1 was revised again in 1975, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1988, 1990, 1992, 1994, 1996, 1998, 2000, 2002, 2004, 2006, 2008 and 2010.

From 1972 to 1988, the D1.1 code covered the welding of both buildings and bridges. 1928年，美国焊接协会出版了它的第一个建筑物的熔焊和气制规范版本，称之为规范1，A部分，它在1930年和1937年被修 订和以同样的标题重新发行。
1941年再一次修订，并给以D1.0的名称。
D1.0规范在1946、1963，1966和1969年再次被修订。

1972年，D1.0与D2.0-公路铁路桥梁焊接规范合并， 给以D1.1的名称。
并重新加标题一美国焊接协会（AWS）结构焊接规芯。
D1.1规范以后在1975、1979、1980、1981、1982、 1983、1984、1985、1986、1988、1990、1992、1994、1996、1998、2000、2002、2004、2006、2008和12010年被再次修订。

In 1988, AWS published is first edition of AASHTO/AWS D1.5, Bridge Welding Code; coincident with this, the D1.1 code changed references of buildings and bridges to statically loaded and dynamically loded structures, respectively, in order to make the document applicable to a broader range of structural applications. Afer the publishing of the 2010 edition, it was decided that the AWS Srnactra Welding CodStee would be published on a five year reviso...
