Abstract
A process of depositing layers of weld metal onto a ferrous NiMoV low alloy steel turbine component. During a deposition of a first layer of weld metal, low levels of amperage are used to prevent a dramatic increase in a level of hardness of a heat affected zone produced during the deposition of the first layer of weld metal. During a deposition of a second layer of weld metal, higher levels of amperage are used to temper the heat affected zone but not high enough to overtemper the HAZ.
