Manual gas pressure welding and hot extrusion gas pressure welding! A global standard backed by overwhelming achievements and trust.
Introducing "Gas Pressure Welding" by Hokuriku Gas Pressure Welding Co., Ltd. Developed in 1952 by the founder of Hokuriku Gas Pressure Welding. Since then, it has spread nationwide as a strong and reliable method for rebar joints in construction work, and has been in use for nearly 60 years to this day. The ends of the rebar are aligned, and while applying pressure in the axial direction of the rebar, the joint area is heated with an oxygen-acetylene flame, bringing the joint surfaces to a red-hot state without melting the metal, allowing the clean surfaces of the metal to adhere closely and fuse at the atomic level.

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.
