Method for hardening nickel alloy welding |
摘要 |
An age-hardenable nickel base alloy welding process involves covering the weld metal with a ductile material cover layer before hot isostatic pressing. In the welding of an age-hardenable nickel base alloy workpiece using a similar filler material, the weld metal is covered with a tight cover layer (4) of ductile material before the workpiece (5) is hot isostatic pressed. Preferred Feature: The cover layer consists of a welded top layer of a ductile nickel base alloy, a solder deposit or a thermally sprayed deposit and is removed before use of the workpiece. |
