Method and apparatus for equilizing temperature of pipe sections during solid phase welding |
摘要 |
In solid phase or pressure welding of adjacent pipe ends wherein a burner ring or other heating element extends circumferentially around the pipes adjacent the joint therebetween, an axial flow of air is directed along the pipe adjacent the weld zone whereby the adjacent pipe ends may be more uniformly heated and thereby produce a better weld.
