Abstract
Principles of evolution of gas bubbles ahead of the solidification front in wet underwater welding have been investigated using mathematical modeling. Dependence of the effect of solidification rate, hydrostatic pressure and hydrogen concentration on critical radius of a gas bubble and dynamics of its variation have been studied on the basis of the results of the numerical experiment.
Keywords: underwater welding, pores, modeling, solidification rate, hydrogen, pressure
