摘要： A welding system and method is provided for welding heavy plate, where the method and device include using a laser which directs a beam to a first weld puddle to weld at least a portion of a work piece and a welding torch to direct a first welding electrode to the first weld puddle while the beam is being directed to the weld puddle. The welding torch deposits the first welding electrode to create a first weld bead. A flux nozzle is employed to deposit a welding flux onto the weld bead, and a submerged arc welding torch is used to direct a submerged arc filler metal to the weld bead to create a second weld bead through a submerged arc welding process, where the submerged arc welding process melts a portion of the first weld bead to consume the melted portion into the second weld bead.

摘要： A method and system to start and use a combination wire feed and energy source system for any of brazing, cladding, building up, filling, and hard-facing overlaying applications. High intensity energy is applied onto a workpiece to heat the workpiece. One or more resistive filler wires are fed toward the workpiece at or just in front of the applied high intensity energy. Sensing of when a distal end of the one or more resistive filler wires makes contact with the workpiece at or near the applied high intensity energy is accomplished. Electric heating current to the one or more resistive filler wires is controlled based on whether or not the distal end of the one or more resistive filler wires is in contact with the workpiece. The applied high intensity energy and the one or more resistive filler wires are moved in a same direction along the workpiece in a fixed relation to each other.
