Zhengde Rebar Gas pressure welding of steel bars is to use the high-temperature flame burned by acetylene-oxygen mixture to heat the joint of two steel bars with initial pressure, so that the ends of the steel bars produce plastic deformation, and promote the mutual diffusion of metal atoms on the end faces of the steel bars. When the steel bars are heated to Pressurized upsetting at about 1250~1350°C (equivalent to 0.80~0.90 times the melting point of steel) to weld the steel bars together..
