We would like to introduce Hokuriku Gas Pressure Welding Co., Ltd.'s "DB Head Fixation Method." In recent years, with the increasing strength and larger diameters in rebar construction, traditional bending anchor methods have encountered issues such as difficulties in bending processing and longer fixation lengths, leading to problems in rebar installation. The "DB Head Fixation Method" addresses these issues. 【Features】 ■ No anchors, significantly improving on-site workability ■ Compatible with rebar from almost all domestic manufacturers ■ Simple distribution routes allow for immediate delivery ■ Capable of handling small lots ■ Significant economic benefits in terms of shortened construction periods and during transportation and unloading ■ High reliability due to the absence of joint surfaces and weld surfaces, with the visible product shape indicating its functionality *For more details, please refer to the PDF document or feel free to contact us.

"Flare welding" is a method of joining parts by overlapping them and using arc welding. By overlapping materials through flare welding, the strength of the rebar itself is also improved. It is used for banding and hoop reinforcement in pile head reinforcement work, seismic reinforcement, elevated bridge construction, etc. A qualification is required to perform flare welding. First, there is the basic level "Downward SA-2F," and the type of qualification varies depending on the working posture. For welding from bottom to top, such as in pile head reinforcement work, "Vertical SA-2V" is required, while for horizontal welding, such as for column bands and hoop reinforcement, a specialized level "Horizontal SA-2H" is necessary. [Features] ■ SA-2F (Downward) ■ SA-2V (Vertical) ■ SA-2H (Horizontal) *For more details, please refer to the PDF materials or feel free to contact us.

The polymer natural gas pressure welding joint "Eco Speed Method" is a new gas pressure welding method that uses a polymer reducing agent "PS Ring" instead of the conventional reduction flame used in gas pressure welding. By using natural gas, it reduces environmental impact and improves the reliability of the pressure welding work. 【Features】 ■ The PS Ring is sandwiched between the end faces of the rebar before welding, preventing oxidation with the decomposition gas generated by heating. ■ The PS Ring is composed of polystyrene and a steel ring, achieving A-class joints at -2. ■ It has passed the "Gas Pressure Welding Performance Evaluation Criteria" and obtained method certification. ■ The performance has been confirmed as an A-class joint type. ■ It is environmentally friendly. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce "Gas Pressure Welding" by Hokuriku Gas Pressure Welding Co., Ltd. It was 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 them, allowing the clean metal surfaces to adhere closely together, and fusing the atoms for a solid joint. [Overview] ■ Manual Gas Pressure Welding ■ Automatic Gas Pressure Welding ■ Hot Extrusion Gas Pressure Welding *For more details, please refer to the PDF materials or feel free to contact us.

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.

The "EcoWell Method" is a rebar gas pressure welding technique that uses clean natural gas, contributing to reduced environmental impact and improved work safety. The gas flow adjustment and hydraulic operation of the welding process are automated, allowing for excellent quality without variations in construction. Additionally, construction data for each welding point is recorded as electronic data, which can be used for quality and construction management after the work is completed. 【Features】 ■ Environmentally friendly ■ Excellent workability and quality ■ Construction management enabled by traceability ■ Construction by certified companies ■ Management of the quality of the EcoWell gas and dedicated equipment used *Please contact us for more details.
