AWS D1。3/D1。3M:2018包含结构钢板/钢带的电弧焊要求，包括冷成型构件，以下统称为“钢板”，其标称厚度等于或小于3/16 in[5 mm]。此外，壁厚小于1/8 In[3 mm]的焊接空心结构截面（HSS）也被称为管状构件，也包括在本规范的范围内。HSS构件连接的设计要求不在本规范的范围内。当本规范在合同文件中有规定时，除工程师或合同文件明确修改或免除的规定外，应要求符合其所有规定。

AWS D1.3/D1.3M:2018 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 [5 mm] in nominal thickness. In addition, welding hollow structural section (HSS) also called tubular members with wall thickness less than 1/8 in [3 mm] are included in the scope of this code. Design requirements for HSS member connections are not in the scope of this code. 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.
