Abstract
Preheated interval welding methods for welding a weld material to a substrate material can include preheating the substrate material to a preheat temperature less than a solidus temperature of the substrate material, melting the weld material to produce molten weld material at a melting distance away from the substrate material, and applying the molten weld material in a plurality of intervals to the substrate material.
Claims20
A preheated interval welding method for welding a weld material to a substrate material, the preheated interval welding method comprising:
- preheating the substrate material to a preheat temperature less than a solidus temperature of the substrate material;
- melting the weld material to produce molten weld material at a melting distance away from the substrate material;
- and
- applying the molten weld material in a plurality of intervals to the substrate material.
A preheated interval welding method for welding a weld material to a substrate material, the preheated interval welding method comprising:
- disposing a welding apparatus adjacent a substrate material;
- preheating the substrate material to a preheat temperature less than its solidus temperature;
- transitioning the welding apparatus element away from the substrate material and adjacent to the weld material;
- melting the weld material to produce molten weld material;
- and
- applying the molten weld material in a plurality of intervals to the substrate material.
A preheated interval welding system for preheating a substrate material and applying a weld material, the preheated interval welding system comprising:
- a preheating apparatus that preheats a repair surface of the substrate material to a preheat temperature;
- and
- a welding apparatus that melts the weld material into molten weld material and applies the molten weld material to the repair surface in a plurality of intervals.
