Abstract
Methods are considered for regulation of thermal cycle of the HAZ metal in coated-electrode arc welding directly in the water. A finite-element mathematical model of thermal processes is developed which allows forecasting the lowering of the cooling rate at the expense of thermal insulation of the heated surface of the metal being welded from the water.
Keywords: wet underwater welding, coated electrodes, thermal cycle, cooling rate, finite element method, experimental investigations, thermal processes
