Abstract

Cracking associated with welds operating in high temperatures and high pressure, is a problem of consideration. The performance of welded joints, both during fabrication and operation depends strictly upon the microstructure of the heat-affected zone (HAZ), which, in a steel of a given composition, is a function of welding conditions and joint geometry. The methodology of prediction of the dimensions of the zones containing different sizes in the HAZ grain of a single-bead weld of 1.25Cr-1Mo-0.25V steel using SMAW deposition process is described. The standard heat-flow equations have been used to determine weld thermal cycles in conjunction with basic metallurgy including phases-transformation, grain growth kinetics and empirical equations to describe the effects of welding variables on weld bead dimensions.
