Abstract
A brazing press for securing exterior claddings to bottoms of metallic receptacles, which includes a support structure and a reciprocable mandrel for exerting pressure against the former. The support structure holds a massive inductor block having a flat bottom and containing an inductor coil for respectively pressing and heating the flat portions of the workpieces, and an encompassing sleeve which is associated with an auxiliary inductor and exerts pressure on the peripheral curved portions of the cladding. Either the sleeve with its auxuliary inductor of the inductor block can be supported by said structure through resilient means which are calibrated, whereby auxiliary pressure is exerted on the peripheral curved portions independently from the one exerted on the flat central portion, when said mandrel is pushed against the inductor block.
