AWS D1.4-D1.4M:2018 pdf download.Structural Welding Code - Steel Reinforcing Bars
1.1 Scope
This code shall apply to the welding of the following:
(1) Steel reinforcing bar to steel reinforcing bar, and
(2) Steel reinforcing bar to carbon or low- alloy structural steel.
When this code is stipulated in contract documents, conformance with all provisions shall be required, except for those provisions that the Engineer or contract documents specifically modifies or exempts.
1.2 Units of Measurement
This standard makes use of both the U.S. Customary Units and the International System ofUnits (SD: the latter are shown within brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents:therefore. each system must be used independently.
1.3 Safety
Safety and health issues and concerns are beyond the scope of this standard: some safety and health information provided.
but such issues are not fully addressed herein.
Safety and Health information is available from the following sources:
American Welding Society:
(1) ANSI Z49.1. Safety in Welding. Cutting. and Allied Processes
(2) AWS Safety and Health Fact Sheets
(3) Other safety and health information on the AWS website
Material or Equipment Manufacturers:
(1) Safety Data Sheets supplied by the materials manufacturers
(2) Operating Manuals supplied by equipment manufacturers
Applicable Regulatory Agencies:
Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous. and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49. l should be considered when devel-oping the safety program.
1.4 Application
1.4.1 General Requirements. This code shall be used in conjunction with the prescribed general building code requirements and is applicable to all welding of steel reinforcing bars, using the processes listed in 1.6, and performed as a part of reinforced concrete construction or in the manufacture of precast concrete components.
1.4.2 Impact Properties. The weldments specified in this code shall not be used where impact properties are a requirement of the general specifcation. Impact testing requirements of welded steel reinforcing bars are not included in this code.
1.4.3 Engineering Approval. All references to the need for approval shall be interpreted to mean approval by the Engineer.
1.5.2 Unknown Composition. When a steel reinforcing bar not listed in 1.5.1 is approved under the provisions of the general building code or by the Engineer, its chemical composition and carbon equivalent shall be provided and welding procedure shall be qualified in accordance with the requirements of 8.2 and all other requirements prescribed by the Engineer.AWS D1.4-D1.4M pdf download.
