In the proposed rule, steel erection was defined as "the erection of" these structures.
Jan 18, 2013 · 6188.8.131.52 Welding. To hold multiple plates tightly together, plates may require a 6 inch long tack weld for stability. When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use is to be utilized. See ASTM A6, Appendix X3 for information on weldability. 626.2.3 Plate Skid Resistance. Structural Bolting Structural Bolting The strength of a weld is dependent on multiple factors, including:base metal, filler metal, type of weld, throatand weld size Strength of Structural Welds (Part of Table J2.5 AISC 2005) 30 Tack Weld (above left) A temporary weld used to hold parts in place while more extensive, final welds are made Continuous Weld
