AWS D1.3/D1.3M PDF

This code contains the requirements for arc welding of structural sheet/strip steels, including cold formed members, hereafter collectively referred to as "sheet steel," which are equal to or less than 3/16 in (0.188 in) [4.8 mm] in nominal thickness. When this code is stipulated in contract documents, conformance with all its provisions shall be required, except for those provisions that the Engineer or contract documents specifically modifies or exempts.

When used in conjunction with AWS D1.1, conformance with the applicable provisions of Annex A of AWS D1.3 shall apply (see also Table 1.1). Two weld types unique to sheet steel, arc spot, and arc seam are included in this code.
