Described herein are examples of weld training systems that show (e.g., transparent and/or translucent) “ghost” images of a welding tool on a display screen of a welding headgear to indicate target positions and/or target orientations of an actual welding tool. In some examples, the weld training systems may additionally “reset” the target tool image to a position closer to the actual welding tool if the target tool image gets too far away. The ability to “reset” the target tool image to a position closer to the actual welding tool may help in minimizing a risk that an operator 106 will overcompensate to try to catch up with the target tool image, which can be detrimental to the weld. Additionally, resetting the target tool image to a position closer the welding tool may allow an operator to better perceive and/or understand differences in orientation and/or other technique parameters.

Systems and methods for the manufacture of a solid wire using additive manufacturing techniques are disclosed. In one embodiment, a fine powdery material is sintered or melted or soldered or metallurgically bonded onto a metal strip substrate in a compacted solid form or a near-net shape (e.g., a near-net solid wire shape) before being turned into a final product through forming or drawing dies.

Embodiments of welding systems and methods with coordinated dual power outputs supporting a same welding process or a same AC output process are disclosed. One embodiment of a welding system includes an engine and a generator operatively connected to the engine, where the engine is configured to drive the generator to produce electrical input power. The welding system also includes a power supply operatively connected to the generator and having at least one controller. The power supply is configured to convert the electrical input power to form two power outputs that are coordinated with each other, at least in time, via the controller to support a same welding process. The same welding process may be, for example, a hotwire welding process, a tandem metal inert gas (MIG) welding process, or an alternating current (AC) output process.

An orientation and guide mechanism for a welding system includes a pair of opposed guide members. A weld wire having a non-round cross-section is fed through a guide passageway formed between the guide members, each of which have recessed channels that combine to define the guide passageway. The guide passageway has a non-round shape corresponding to the non-round shape of the wire. The orientation mechanism and the guide members thereof is adjustable relative to a welding device of the weld system, such that the orientation of the wire can be controlled and maintained by adjusting the orientation mechanism. The wide side of the wire may be adjusted to be presented to a radiant energy source, and/or the non-round wire may be adjusted relative to the desired weld seam.

The invention relates to an electrode (16) for a welding torch (17) or a cutting torch, comprising a main body (1) and a tip (3) arranged on an end surface (2) of the main body (1). The main body (1) is designed as a hollow body that is open on at least one side. On a side opposite one of the tips (3), the main body has an opening (4) for introducing a cooling medium into an interior space (7) of the main body (1), and at least two regions (5, 6) in the interior space (7), the two inner diameters of which are different from one another, and a transition region (8) located between the two regions (5, 6) having an inner diameter that decreases in the direction of the tip (3).
