The method presented in this paper is a new gas pressure welding technology for rebar bonding in the fields of civil engineering and building construction. It uses natural gas, which has less of an environmental impact than the traditionally used acetylene gas, as well as a polymer reducing agent (PS ring) that prevents oxidation of the rebar surface, a major cause of bonding defects. This construction method has the merits of having a low environmental impact through the use of natural gas, and offering the high reliability of gas pressure welding combined with corrosion prevention through the use of a reducing agent.
