A welding system (1) comprising a main module (2) equipped with an external casing (3) in which an inlet port (4) for the connection to an external electric power source, an electric generator (5) configured to adapt the electrical characteristics of the electric power received at the inlet to a first type of welding, an outlet port (6) for the connection by means of an electric conductor (10) to a welding torch (20) and an electronic control unit (7) configured to control the functionality of the electric generator (5) are identified. The welding system also comprises a welding torch (20) configured to be connected by means of the electrical conductor (10) to the outlet port (6).

The invention relates to a device for replaceably fastening a gas nozzle, comprising an elongate support element which has a nozzle portion for fastening a gas nozzle and is provided with a curved mounting portion, and a holding component which is provided with at least one recess which is shaped in such a way that the mounting portion of the support element can be inserted into the recess so as to produce a form-fitting engagement between the support element and the holding component.

A method for manufacturing an additively-manufactured object, in which a plurality of weld beads obtained by melting and solidifying a filler metal are deposited on a base portion to build a built-up object, includes: a support bead forming step of forming a support bead on the base portion; and a depositing step of depositing a weld bead on the support bead. When the support bead is formed to be inclined from a vertical direction in the support bead forming step, a ratio H/W of a height H to a width W of the support bead is set to 0.35 or more.

A welding torch that comprises: a main body that is formed as a hollow pipe body, and that has a first inclined surface formed inside the pipe body; an electrode bar cap that has a collet chuck on the front side of a joint that is assembled on one side of the pipe body in a screw-coupling manner, that moves the collet chuck by tightening or loosening the joint; a head that has a socket that is arranged on a side facing the pipe body and that sprays supplied gas in all directions, and that is formed of a nozzle that is assembled on an external surface of the socket; and a connector that guides a gas supply into the pipe body.

A welding torch 10 is provided for use in a Gas Metal Arc Welding (GMAW) process. The welding torch 10 includes a torch body 12, a welding tip 16 extending from the torch body 12, and a detachable nozzle 22 which substantially surrounds the welding tip 16 in use to direct gas around the welding tip 16 and onto a workpiece, the nozzle 22 having a front end which faces the workpiece in use and a rear end which attaches to the torch body 12 in use, in which a ring 24 is provided, the ring 24 being substantially axially fixed to the nozzle 22 at the rear end of the nozzle 22, and the ring 24 being rotatable with respect to the nozzle 22, the ring 24 having a screw thread and the torch body having a corresponding screw thread 26, for fixing the nozzle 22 to the torch body 12.

A plasma arc torch includes a nozzle body, a nozzle extending from the nozzle body, and a shield cap. An outer retaining cap is attached to the plasma arc torch and secures the shield cap to the plasma arc torch. A sleeve is located radially outward from the outer retaining cap and is configured to receive a flow of pressurized gas. An insulator is located between the outer retaining cap and the sleeve. At least one of the sleeve and the insulator forms a gas flow channel configured to direct a gas flow from the sleeve to a distal portion of the outer retaining cap.

An example wire liner retention apparatus includes: a body comprising a bore extending longitudinally through the body, the bore configured to permit passage of a welding wire liner through the bore; a clamp configured to apply a compressive force to the welding wire liner in a radial direction within the bore to limit movement of the welding wire liner with respect to the body; and a compression adjustment mechanism configured to adjust the compressive force applied by the clamp.

A tungsten inert gas welding torch body, a TIG welding torch handle, and a TIG welding torch has a gas channel terminating in front of the distal end of a plug-in element in an inlet opening arranged on the shell side of the plug-in element, and a central inlet mouth at the distal end of the plug-in element terminating in front of the distal end of the plug-in element in a return opening on the shell side at the plug-in element. The TIG welding torch handle has a second channel arranged coaxially to the central channel, and a third channel arranged coaxially to the second channel. A connection is between the second channel and the third channel. The first channel has a mouth in the center of the receiving part, and each of the second and third channels has a mouth on the shell side of the receiving part.

Apparatus, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

Aspects of a welding-type cable and torch are provided. The welding-type cable includes a power conductor to conduct welding-type power and a weld torch interface on a distal end of the welding-type cable to attach a weld torch to the power conductor. The welding-type torch includes a power connector to transfer welding-type power between the welding-type torch and a power conductor of a welding-type cable that is detachably coupled to the power connector. An electrode to perform a welding-type operation using the welding-type power is also provided.
