AWS D1.4:2005 pdf download.Structural Welding Code— Reinforcing Steel
1.2 Application
1.2.1 This code shall be used in conjunction with the pre- scribed general building code requirements and is appli- cable to all welding of reinforcing steel, using the processes listed in 1.4, and performed as a part of rein- forced concrete construction. 1.2.2 The weldments specified in this code shall not be used where impact properties are a requirement of the general specification. Impact testing requirements of welded reinforcing bars are not included in this code. 1.2.3 All references to the need for approval shall be interpreted to mean approval by the Engineer.
1.3 Reinforcing Steel Base Metal
1.3.1 Reinforcing steel base metal in this code shall con- form to the requirements of the latest edition of one of the ASTM specifications listed within this paragraph. Combinations of any of these reinforcing steel base met- als, when welded, shall use a WPS (welding procedure specification) qualified in conformance with Section 6.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 pro- visions 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 weldability 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 D1.1, 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 be 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:
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 Z49.1, Safety in Welding, Cutting, and Allied Processes 2. Manufacturer’s safety literature on equipment and materials 3. Other pertinent documents as appropriate. These documents shall be referred to and followed as required (also see Annex D, Safe Practices). Note: This code may involve hazardous 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 limitations prior to use.
1.8 Standard Units of Measurement
This standard makes use of both U.S. Customary Units and the International System of Units (SI). The measurements may not be exact equivalents; therefore, each system shall be used independently of the other without combining in any way. The standard with the designation D1.4:2005 uses U.S. Customary Units. The standard designation D1.4M:2005 uses SI Units. The latter are shown within brackets [ ].
1.9 Reference Documents
The following standards contain provisions which, through reference in this text, constitute provisions of this AWS standard. For undated references, the latest edition of the referenced standard in use at the date of the contract bid submission shall apply. For dated refer- ences, subsequent amendments to, or revisions of, any of these publications do not apply. ASNT Standards 1 1.
