<p>PURPOSE:To relieve high residual stress produced in a thick-walled structural member when the member is subjected to a build-up welding by keeping the build-up surface of the member at a low temp. and heating the other side. CONSTITUTION:Corrosion resistant clad steel is joined to one side (inside) of a thick-walled structural member for a nuclear reactor container, etc. by the build-up welding. The build-up surface of the member is kept at a relatively low temp. by cooling, and the other side (outside) is heated to relieve high residual stress produced in the member during the build-up of the clad.</p> |
