Abstract
The most widely used metal underpinning modern industry is steel (carbon steel). Low-alloy steel designed to increase the strength and heat resistance of basic carbon steel and stainless steel to offer improved corrosion resistance and oxidation resistance are extensively used in the manufacture of thermal and nuclear power plants, chemical plants, etc. An extremely important and unavoidable practical requirement in modern steel construction technology is to be able to perform dissimilar welding of stainless steel to carbon and low-alloy steels (welding of dissimilar metals). This article profiles the basic principles and noteworthy features of dissimilar welding of stainless steel to carbon and low-alloy steels.
