8. METALLURGY & WELDING - SAC Steel

Metallurgy & Welding 8-2 Commentary:Many WSMF structures designed in the last 10 years incorporated ASTM A36 steel for the beams and ASTM A572 grade 50 steel for the columns. This provided an economical way to design structures for the strong column - weak beam provisions contained in the building code. Recent studies conducted APPENDIX F GUIDELINES FOR WELDING STRUCTURAL 2. Welding Operator - definition. a. A person who operates automatic welding equipment. b. Shop Welding Operator:(1) A person employed by the Contractor or fabricator to operate welding equipment in a fabrication plant. (2) Must be qualified by tests conducted at the plant and witnessed by an independent inspection agency.

ASTM A572 / A572M - 18 Standard Specification for High

1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures. Grades 60 [415] and 65 [450] are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.

Welding Research

Welding is the principal method for joining steel. But even more signifi­ cant, welding is vital as a practical method for fabricating steel structures and pressure vessels for modern liv­ ing. From thi point of view, welding is as important to a fabricator as oxygen cutting, forming, and machin­ ing. However, welding ASTM A572 Grade 50 - A572 Grade 42, 50, 60, 65 Steel Material Properties The following material properties are ASTM specifications and will be confirmed on the Mill Test Report.
