    摘要: A method of welding alloys having a ductility drop temperature range to limit strain-age cracking. The method involves the use of a welding device to weld a weld area of an article while maintaining temperatures throughout the weld area and a heat affected zone adjacent the weld area within a non-crack sensitive temperature range that is above a ductility drop temperature range of the alloy being welded. During welding, the temperatures of the weld area and the heat affected zone are predominantly controlled with heat input from the welding device. Once the welding has been terminated, the weld area and the heat affected zone are cooled from the non-crack sensitive temperature range through the ductility drop temperature range to a temperature below the ductility drop temperature range of the alloy.

    摘要: An apparatus and process for depositing an overlay weld on a substrate in a manner that reduces dilution of the substrate material. A consumable electrode is positioned in proximity to the surface of the substrate, and an electrical potential is applied between the electrode and substrate to generate an electrical arc therebetween. The arc melts the electrode and forms a molten spray that deposits on the substrate surface. Energy of the electric arc is absorbed to reduce the temperature at the substrate surface by feeding an additional filler material into the electric arc toward its center axis. The filler material continuously melts prior to reaching the center axis of the electric arc, and the electrode and filler materials are simultaneously deposited to form the overlay weld on the substrate. Sufficient energy is absorbed by the filler material to reduce intermixing between the overlay weld and the substrate.
