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 enclosure welding using ceramic backing materials. After the welding operation, the backing can be removed, allowing for visual inspection of the weld appearance. This method was jointly developed by Osaka Prefecture and Aichi Institute of Technology, focusing on stable quality. It is used in various construction projects, regardless of whether they are in architecture or civil engineering, and particularly for large diameters (D35 and above), it has achieved approximately 500,000 instances per year. 【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 mainly conducts gas pressure welding work for rebar related to civil engineering and construction projects. "Gas pressure welding" involves butting the ends of rebar together, applying pressure in the axial direction of the rebar while heating the joint area with an oxygen-acetylene flame, bringing the joint surfaces to a red-hot state without melting them, ensuring the clean metal surfaces adhere closely, and fusing the atoms of the metal together to create a joint. We have a wealth of experience, particularly in Kanazawa, including projects such as Kanazawa Station, museums, and sports centers.
