Metallic parts are bonded to form a component, esp. for stationary gas turbines, by (A) placing an intermediate layer or layers of defined thickness between the parts, heating the assembly to a predetermined temp., applying a predetermined pressure to the parts before or after heating, and maintaining the temp. and pressure until isothermal solidification of the intermediate layer and/or the alloying materials of the parts occurs at the joint region; or (B) placing an intermediate layer or layers of 1-50 microns thickness between the parts, brazing the layer(s) to the parts in the joint region in a short time but at least until a sealed brazed joint is obtained, cooling the assembly, and isostatically pressing the joint region at 1120-1160 deg.C, pref. rising to 1180-1220 deg.C. |
