Abstract
PURPOSE: To perform a three-dimensional heating operation and to prevent the butted surfaces of steel materials from being overheated by a method wherein the steel materials to be pressure-welded to each other are heated by each of the fire tips of the burner at portions adjacent the butted surfaces of the steel materials.
CONSTITUTION: The U-shaped body 2 of the multihole type gas burner 1 is provided with the fire tips or nozzles 3 at four positions thereon, that is, at the tops and the base portions of U-shaped arms 2a of the body 2. Further, a blind fire hole 4 whose base portion is in communication with the burner body 2 is drilled along the axis of each of the fire tips 3 and a couple of radial branch fire tips 5 which communicate with the blind fire hole 4 and which open at the top end of the fire tip 3 are drilled in symmetrical relationship with each other with respect to the axis X of the fire hole 4. Accordingly, the heating operation for the butted steel materials can be performed in a three-dimensional fashion from the beginning without the necessary of performing the conventional broad burning effected through the movement of the burner 1 so that no overheating of the butted section of the steel materials will occur.
