Method for fitting or plugging a first connecting part into a second connecting part of a processing head for thermal material processing, the first connecting part having, on an encircling outer face, and/or the second connecting part having, on an encircling inner face, at least one slot, extending at least around a partial circumference, with a slot width B130, B230 and a slot depth T130, T230, T112, T120, which receives an O-ring or profile ring, extending around the entire circumference, with a cord size Sa, wherein, when the first connecting part is fitted or plugged into the second connecting part, the O-ring or profile ring is initially in contact with the opposite inner face or opposite outer face only around a partial circumference, which extends along the slot, or around a plurality of partial circumferences, which extend along the slot, and connecting parts and arrangements made up thereof.

The disclosure includes a welding cup system comprising a tube having an open top, an open bottom, a sidewall extending between the open top and the open bottom, and an open channel. The open channel may extend through an interior portion of the tube from the open top to the open bottom. The open top may be arranged and configured to slideably couple to at least a portion of a torch assembly. The open channel may be arranged and configured to allow gas to flow from the open top to the open bottom, and allow a welding electrode to extend through the open channel from open top towards the open bottom. The welding cup system may have a side profile that may define an asymmetrical shape.

A nozzle assembly for a welding torch is disclosed. The nozzle assembly comprises a nozzle, a contact tip, and a gas diffuser assembly. The gas diffuser assembly comprises a gas diffuser, coupled to an insulator. The gas diffuser is also coupled to a gooseneck and the contact tip. The nozzle is coupled to the gas diffuser assembly, such that the contact tip is retained within the nozzle. The nozzle and gas diffuser assembly further include complementary engagement features to couple the nozzle to the gas diffuser assembly. The nozzle also includes a spatter deflector configured to deflect or block spatter from obstructing gas holes of the gas diffuser assembly.

A fastening system for welding a welding stud in a welding direction to a substrate is provided, comprising a welding gun, which defines the welding direction, and the welding stud, wherein the welding gun has a holding device for holding the welding stud during a welding process and an outer contour, wherein the welding stud comprises a contact surface, which is provided for making contact with the substrate before and/or during the welding process, and wherein, starting from the contact surface, a tangent can be applied to the outer contour, which encloses an angle of less than 60° with the welding direction when the welding stud is held by the holding device and the contact surface is in contact with the substrate.

Embodiments of systems, apparatus, and methods to support the simulation of a shielded metal arc welding (SMAW) operation are disclosed. One embodiment is a tip assembly that includes an elongate mock electrode tip having a proximal end, a distal end, and a locking sleeve near the proximal end.
