It can be easily done even in narrow spaces! We will introduce the standard method for welding reinforced concrete joints.
The "CB Method" refers to an enclosed welding technique that uses ceramic backing materials. After the welding operation, the backing can be removed, allowing for visual inspection of the weld's appearance. This method was jointly developed by Osaka Prefecture and Aichi Institute of Technology, focusing on stable quality. It is utilized in various construction projects, both in architecture and civil engineering, particularly for large diameters (D35 and above), with an annual achievement of approximately 500,000 locations. 【Features】 ■ High reliability of joint performance ■ Good workability of joint shape ■ Reliable quality control ■ Speedy welding operations ■ Expanding possibilities for construction methods ■ Market area: Hokuriku only *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company primarily conducts gas pressure welding work for rebar related to civil engineering and construction projects. "Gas pressure welding" involves butting the ends of rebars together, applying pressure in the axial direction while heating the joint area with an oxygen-acetylene flame, bringing it to a red-hot state without melting the joining surfaces, allowing the clean metal surfaces to adhere closely and fuse the atoms together for joining. We have a wealth of experience, particularly in Kanazawa, including projects such as Kanazawa Station, museums, and sports centers.
