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

AT&F fabricates a wide variety of materials into ready-to-assemble or fully assembled components for commercial and military applications. We will accept customer supplied material or purchase from one of our reliable vendors. Our purchasing department has many years of experience in the industry and well-established relationships with mills and suppliers. Our staffs Ph.D. Metallurgist Normalized A572 Gr 50? - Metal and Metallurgy engineering May 17, 2007 · You might want to look into a material change to A633. A633 is a low alloy steel, normalized, with a grade C and D with 50 ksi min, suitable for welding, where low temperature properties are better than comparable strength as- rolled steels. Expect the need for suitable welding procedures. A633 is a very nice material where low temp. Notch Toughness - an overview ScienceDirect TopicsR.S. Chandel, B.

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.
