Title:
METHOD FOR MAKING A FAILURE-RESISTANT DAMPER
Document Type and Number:
WIPO Patent Application WO/1985/003114
Kind Code:
A1
Abstract:
The method for making the failure-resistant damper provides for fabricating a hollow cylindrical blank (1) of which the multilayer wall is provided with an artificial discontinuity (2) taking place at least in one of its layers. The diameter of the blank is smaller and the thickness thereof is larger than the specified final geometrical sizes of the failure-resistant damper (5). The blank (1) is heated and is then rolled through a ring rolling mill (4) along the whole length of the blank (1) until achieving the final geometrical sizes of the failure-resistant damper (5). During rolling the layers are welded therebetween.
