Factors affecting weld metal properties in carbon and low alloy pressure vessel steels
The properties of some weld metals have been inferior to those of the steels that they joined. The problem exists for certain pressure vessel weldments currently being fabricated. As a result, it has not been possible to use some pressure vessel steels for certain desirable applications. The effects of interrelated factors such as microstructure and composition on the mechanical properties of as-deposited and stress-relieved weld metals are described. Factors such as welding procedures, welding processes and positions, and postweld heat treatments that also influence weld properties are discussed. Descriptive and tabulated information about current pressure vessel steel and weld metal properties are presented with a discussion of weld metal problems that limit the potential uses of pressure vessel steels.
