PROCESS FOR COPARALLEL JOINING OF PLATE METAL BY BRAZING, IN PARTICULAR FOR PREPARING A PLATE-SHAPED HEAT EXCHANGER, AND HOLDING MEANS THEREFOR

摘要

process of assembling by soldering two parallel metal plates, at a minimum, each of at least one hole drilled, in particular to a heat exchanger plate.which is related with the plates in parallel to one another.the holes are maintained in the face of the other by a curved attachment on the edges of the holes.during brazing, the attachment maintains the metal plates so as to make very small gaps between the sides of the attachment and the plates.as well as between two consecutive sheets. in addition, the attachment can be used to deposit the weld metal for brazing, brazing the joint.
