[4S/DF] AWS D1.5:2002 Bridge Welding Code

This code covers the welding requirements for AASHTO welded highway bridges made from carbon and low-alloy constructional steels. This 2002 edition contains dimensions in metric SI Units and U.S. Customary Units. Sections 1 through 7 constitute a body of rules for the regulation of welding in steel construction. Section 9 of the previous edition has had its provisions distributed throughout the 2002 edition. Sections 8, 10, and 11, do not contain provisions, as their analogue D1.1 sections are not applicable to the D1.5 Code. Section 12 contains the requirements for fabrication fracture critical members.
