AWS D1.4/D1.4M:2018 – Structural Welding Code – Steel Reinforcing Bars

AWS D1.4/D1.4M:2018 – Structural Welding Code – Steel Reinforcing Bars provides welding requirements for deformed and plain reinforcing bars used in reinforced concrete construction. Applicable to structural projects such as buildings, bridges, and infrastructure systems, this code ensures weld quality, safety, and compliance in both field and shop conditions.

Highlights:

• Covers Shielded Metal Arc Welding (SMAW) and Gas Tungsten Arc Welding (GTAW) as prequalified processes
• Design rules for welded joints, lap splices, and bar anchorage
• Base metal, filler metal, and electrode specifications
• Preheat/interpass temperature guidance based on carbon equivalent
• Weld profile and workmanship requirements
• Qualification criteria for welders, welding procedures, and inspectors
• Visual and radiographic inspection procedures
• Surface preparation and protection requirements for field/shop welding
• Includes normative and informative annexes for expanded guidance
• Commentary section explains code intent and technical decisions

Who It’s For:
Structural engineers, contractors, inspectors, and welders engaged in the welding of reinforcing steel in seismic, heavy civil, and structural applications.
