Study on Production Mechanism of Welding Residual Stress at the Juncture of a Pipe Penetrating a Thick Plate.

Abstract

This paper studies welding residual stresses at the intersection of a small diameter pipe penetrating a thick plate. The pipe is welded to the plate, and Tungsten Innert Gas (TIG) cladding is melted on the inner surface of the pipe to protect it from stress corrosion cracking due to long operation in nuclear power plants.
