Welding of Reinforcing Bars in Reinforced Concrete Construction
Also Known As:
The CSA W186:21 standard is a set of guidelines for the certification of companies engaged in the fusion welding of reinforcing bars in concrete construction. This standard supersedes previous editions and has been updated to reflect recent experience and knowledge.
The standard covers various aspects of the welding process, including the certification of companies, weld design, fabrication, and inspection. It emphasizes that certification does not approve specific products or services but ensures that certified companies have the necessary organization, personnel, welding procedures, and equipment to produce satisfactory welds.
The scope of the standard includes the certification of companies engaged in fusion welding, as well as the qualification of personnel and welding procedures. It also covers the design, fabrication, and inspection of welded connections using deformed reinforcing bars, as well as the welding of these bars to other structural or low-alloy steel members.
The standard lists various welding methods that are included, such as shielded metal arc welding, gas metal arc welding, flux-cored arc welding, metal-cored arc welding, and gas tungsten arc welding. However, it does not cover the welding of plates or other structural members, welding of reinforcing bars with specified yield strength exceeding 550 MPa, or welding of stainless steel.
It is important to note that the standard does not address safety issues associated with welding and welding practices, as the CSA W117.2 standard should be followed for safety considerations. Additionally, it does not address underwater welding activities.
