ABSTRACT:
A process for the production of welded mesh suitable for the reinforcement of concrete. Rod exiting from the finishing stand of a hot mill is superficially cooled in a water quench to an equalization temperature of between 300.degree. C. and 700.degree. C. The rod is then further cooled in air to temper the bainitic or martensitic outer surface layer so produced, and is then arranged to form a mesh and welded at the overlaps. No drawing or mechanical working of the rod takes place between cooling and forming the mesh.
