AWS D1.4 pdf free download.Welding Code- Reinforcing Steel.
7. ASTM A 934/A 934M
Manufacturing and testing requirements for mats and fabric are covered by the respective ASTM specification. For joining the ASTM A 82/A 82M and A 496/A 496M to other reinforcing wires, reinforcing bars, or structural steels, the Engineer shall specify filler metal and the provisions of this code shall apply.
1.3.2 When a reinforcing steel not listed in 1.3.1 is approved under the provisions of the general building code or by the Engineer, its chemical composition and carbon equivalent shall be provided and its weldahility established by qualification in accordance with the requirements of 6.2 and all other requirements prescribed by the Engineer.
1.3.3 Base metal, other than those previously listed, shall be one of the structural steels listed in the latest edition of AWS D 1. 1. Structural Welding code—Steel. or any steel stipulated in the contract documents or approved by the Engineer.
1.3.4 The carbon equivalent of reinforcing steel bars shall he calculated as shown in 1.3.4.1 or 1.3.4.2, as applicable.
1.3.4.1 For all steel bars, except those designated as ASTM A 706, the carbon equivalent shall be calculated using the chemical composition, as shown in the mill test report, by the following formula:
C.E.=%C+%Mn/6 (Eq. I)
1.4 Welding Processes
1.4.1 Welding shall he performed with shielded metal arc welding (SMAW), gas metal arc welding (GMAW), or flux cored arc welding (FCAW).
1.4.2 Other welding processes may be used when approved by the Engineer, provided that any special qualification test requirements not covered here are met to ensure that welds satisfactory for the intended application will he obtained.
1.5 Definitions
The welding terms used in this code shall be interpreted in accordance with the definitions given in the latest edition of AWS A3.O, Standard Welding Terms and
Definitions.
1.6 Welding Symbols
Welding symbols shall he those designated to the latest edition of AWS A2.4. Standard Symbols for Welding. Brazing, and Nondestructive Exam motion. Special conditions shall be fully explained by additional notes or details.
1.7 Safety Precautions
This technical document does not address all welding and health hazards. However, pertinent information can be found in the following documents:
1. ANSI Z49. I, Safety in Welding, Culling, and A tiled Processes
2. Manufacturer’s safety literature on equipment and materials
3. Other pertinent documents as appropriate.
These documents shall he referred to and followed as required (also see Annex D. Safe Practices).
Note: This code may involve ha:ardous materials. operations, and equipment. The code does not purport to address all of the safety problems associated with its use. It is the responsibility of the user to establish appropriate safety and health practices. The user should determine the applicability of any regulatory l,nutauons J)rior to use.
1.8 Standard Units of Measurement
This standard makes use of both U.S. Cusomarv Units and the International System of Units (SI). The measurements may not he exact equivalents; therefore, each system shall be used independently of the other without combining in any way. The standard with the designation Dl .4:2005 uses U.S. Customary Units. The standard designation Dl .4M:2005 uses SI Units. The latter are shown within brackets [1.AWS D1.4 pdf download.
