The Structural Welding Code, hereinafter referred to as the Code, provides welding requirements for the construction of aluminum structures. It is intended to be complementary with any general code or specification for design and construction of aluminum structures.

Although the provisions of the Code are generally applicable to any aluminum structure, owners, architects, and engineers using the Code for structures should recognize that not all of its provisions may be applicable or suitable to their particular structures. However, any modifications of the Code deemed necessary by these authorities should be clearly referenced in the contractual agreement between the owner and the contractor. ¹

1. As used in this commentary, contractor designates the party responsible for performing the welding under the Code. The term is used collectively to mean contractor, fabricator, erector, manufacturer, etc.

Recommended provisions are given in Section 2, Design; Section 3, Workmanship; and Section 4, Technique. Section 4 includes welding procedures, with specific reference to preheat, filler metals, and other pertinent requirements. Additional requirements for recommended joints in tubular construction are given in Section 10.
