| Abstract: | Recent advances in the evaluation of strength and service life of welded structures at high temperature were summarized.A concept of structural creep-rupture equation was proposed to define the weldment creep strength reduction factor.Multiaxial effect was taken into account.Life reduction due to the presence of a weld in high temperature structures was studied. |
