Research on the Effect of Applying the Sacrifice Layer Technique on the Chemical Composition of the Welded Deposits

Abstract

All vessel-type products operating under extreme conditions of temperature, pressure and corrosive environments, such as those in the power, chemical and petrochemical industries, are subjected to intense chemical / structural degradation processes that may lead to cracks. These may propagate in time, causing the product to fail, generating significant economic and material consequences, leading in some cases even to the loss of human lives. The paper presents some effects of the sacrifice layer repairing technique used to restore the geometrical shape by welding of the area from where the flaw material was removed, on the chemical composition.
