Abstract
The process described serves for producing a steel mold for concrete paving setts with so-called spacers, the individual mold chambers being cut out of a steel plate by flame cutting. Grooves are formed in the mold walls by means of the flame-cutting jet, by way of an arcuate movement of the same, the grooves defining the cross section of the spacers. The upper section of the grooves is filled in that closure platelets, of which the cross section corresponds approximately to the cross section of the groove and which exhibit welding projections on their side directed towards the groove, are welded into the groove by projection welding. The closure platelets consist of a strain-hardened unalloyed or low-alloyed steel.
