Abstract
The joints made by fusion of materials are exposed to the influence of
residual stresses induced by welding thermal cycles. Residual stresses
were measured on butt welded plates made of NIOMOL 490K, before and
after reparation. The objective of this paper is to compare three methods
of residual stress measurement (hole-drilling method, x-ray diffraction
and directional effective permeability) induced by two welding processes
(Submerge Arc Welding and Transferred Ionized Molten Energy) of V-butt
welded plates. The residual stresses values are higher after reparation than
before reparation of welded joints.
