ABSTRACT:
A brazing construction and method of brazing an abradable sealing material onto a base material is provided. The abradable sealing material is a tabular member having a cellular compartment construction in honeycomb form having empty compartments and partitions formed by overlapping a plurality of thin corrugated sheets. The abradable sealing material is brazed on the main material by, applying a stop-off agent on a side surface of the abradable sealing material except on a portion of the side surface close to a brazing face to form a stop-off area that prevents infiltration of a brazing filler metal in an overlapping part; superposing the brazing face of the abradable sealing material on the base material, such that the brazing filler metal is provided between the abradable sealing material and the base metal; and brazing the abradable sealing material to said base material.
