1. A method for high deposition, submerged arc welds with metal powder, the method comprising the steps:
a) providing at least one adjustable workpiece having at least one horizontally disposed weld cavity, each horizontally disposed weld cavity comprising a finite length; b) providing an adjustable welding fixture having at least two axes and as many as six axes of controlled motion, the fixture comprising 1) at least one welding torch comprising at least one welding wire, and 2) at least one square wave AC welding power supply; c) filling a single, horizontally disposed weld cavity with a layer of metal powder; d) covering the metal powder layer in the single, horizontally disposed weld cavity with a layer of welding flux; e) positioning at least one welding torch at one end of the single, horizontally disposed weld cavity so that at least one welding wire contacts the metal powder; f) powering at least one welding torch to strike a submerged welding arc in the layer of metal powder; g) moving the welding torch and submerged welding arc along the entire length of the single, horizontally disposed weld cavity; h) repeating steps c) through g) until the weld is completed for the single, horizontally disposed weld cavity; and i) repeating steps c) through h) until all horizontally disposed weld cavities in the workpiece have been welded. |
