Abstract: A system and method for dual-twin SAW cladding is disclosed. The method includes arranging a first twin SAW head in close proximity to a second twin SAW head, delivering electroslag flux to a surface of a workpiece to create a layer of electroslag flux atop the workpiece, directing two first consumable wires through the first twin SAW head towards the surface of the workpiece, directing two second consumable wires through the second twin SAW head towards the surface of the workpiece, introducing the two first consumable wires and the two second consumable wires into a molten slag pool formed on the surface of the workpiece to melt the two first consumable wires and the two second consumable wires via resistive heating, and translating the first twin SAW head and the second twin SAW head together to form a cladded deposit on the workpiece.

Abstract: Granular welding flux delivery devices and strip cladding systems with granular welding flux delivery devices are disclosed. A disclosed example granular welding flux delivery device includes a hopper having: an intake opening to receive granular welding flux; a chute; and an output opening to output the granular welding flux to an electroslag strip cladding process, a submerged arc welding process, or a submerged arc strip cladding process. The example granular welding flux delivery device further includes a chute divider positioned within the chute to reduce an intake rate of granular material through the intake opening by reducing a cross-section of the chute based on a dimension of the chute divider. The disclosed example granular welding flux delivery device includes an adjustable output cover attached to the chute proximate to the output opening to extend or retract a length of the chute by adjusting a location of the output opening along the chute.

Abstract: Stopping electroslag strip cladding operations feeding multiple strips includes detecting, during a welding phase of an electroslag welding operation feeding a first strip and a second strip towards a molten slag pool formed on a work piece, initiation of a stop phase. Upon detection the feeding of the first strip towards the molten slag pool is stopped. Additionally, a feed direction of the feeding of the second strip is reversed to retract the second strip away from the molten slag pool.

Abstract: Methods for laser additive manufacture are disclosed in which a plurality of powder layers (48, 50 and 52) are delivered onto a working surface (54A) to form a multi-powder deposit containing at least two adjacent powders layers in contact, and then applying a first laser energy (74) to a first powder layer (48) and a second laser energy (76) to a second powder layer (52) to form a section plane of a multi-material component. The multi-powder deposit may include a flux composition that provides at least one protective feature. The shapes, intensities and trajectories of the first and second laser energies may be independently controlled such that their widths are less than or equal to widths of the first and second powder layers, their intensities are tailored to the compositions of the powder layers, and their scan paths define the final shape of the multi-material component.

Abstract: An automatic welding method includes a preliminary step and a joining step. The preliminary step is configured to place a metal object having a multi-dimensional curved weld zone on a platform, and to clamp a welding torch with a welding torch clamping device. The joining step is configured to generate a relative movement between a tip of the welding torch and the multi-dimensional curved weld zone of the metal object, and to electrify the welding torch to weld the metal object by way of short circuiting arc transfer. An angle difference between a reference position and an instant position of the welding torch is 0 to 135 degrees when the welding torch welds the metal object, so as to keep the slag from spraying, wherein the welding torch is at the reference position when the tip thereof is pointed straight down towards the ground.
