Abstract

Process for welding by addn. of metal in several layers without inducing porosity at the weld-base metal interface. A plate or rod electrode is used with protective powder. The steels employed are low alloy steels contg. Mo, Cr, Ni and/or V. In welding in two stages the first weld produces a fine region of large grains in the base metal. These grains are refined by being in the heat affected zone of the second weld. By controlling the heat affected zone porosity is avoided thus eliminating the need for new alloys for welding.
