ABSTRACT:
A method of hot pressure welding of hot steel stock, in which the ends of the steel stock are descaled mechanically and pressure joined under a reducing flame. Since re-oxidation after descaling is prevented and the feasible temperature for hot pressure joining is maintained by the reducing flame, the joining is accomplished firmly and strong joints are obtained.
