A connector assembly for a thermal cutting system or welding system can include a housing having a locking device. The locking device can cause, upon application of a translational force, engagement of the connector assembly relative to a stationary receiving mechanism and can cause, upon application of a force on a contact member or a rotational moment on the contact member, disengagement of the locking device relative to the stationary receiving mechanism. The connector assembly can include a conduit disposed in the housing, the conduit carrying a gas to the thermal cutting system or welding system. The connector assembly can include a first current carrying member disposed in the housing, the first current carrying member carrying an operating current to the thermal cutting system or welding system and a second current carrying member disposed in the housing, the second current carrying member carrying a second current.

A hardfacing machine is used for depositing a hardfacing alloy onto a metallic workpiece. An welding unit includes a wire feed system to supply wire to a welding head. A powder alloy feeding system includes a powder feed nozzle fluidly connected to an alloy powder supply. The welding head and powder feed nozzle move in a travel direction relative to the workpiece. The powder feed nozzle is positioned and oriented to feed a powder stream of alloy powder into a molten pool generated on the workpiece by an electrical arc produced by the welding head at a low temperature location behind the welding head relative to the travel direction. This alloy surfacing strategy limits vaporization of alloy elements by avoiding the high temperature region associated with the electrical arc.

A liquid and gas separator to generate a shielding gas from the exhaust gas of an internal combustion engine. The liquid and gas separator can be a separate portable component or a component that is integrated with the arc welder.

A TIG wire feeding pen comprises a heat dissipation pen point, a wire feeding switch, a speed reducer, a wire feeding wheel, a pen shell, a mini type shell, an electric quantity display, a speed regulator, a charging interface, a welding wire guide pipe, a chargeable battery, guide wheels, a pressure adjuster, a battery replacing window and a wire feeding wheel replacing window. The mini type motor and the speed reducer are connected with the wire feeding wheel and provide power for wire feeding, and continuous or different-step-size stepping wire feeding is achieved by replacing circular or different-arc-length fan-shaped wire feeding wheels. The pressure adjuster is used for adjusting the pressure of the guide wheels, and welding wires different in diameter are conveyed out. The wire feeding speed is adjusted through the speed regulator, wire feeding is controlled through the wire feeding switch, and the electric quantity display monitors the residual electric quantity. The heat dissipation pen point is made of a material good in heat conduction coefficient, and welding wire heat dissipation is facilitated. The TIG wire feeding pen is convenient to carry, the labor intensity of workers is relieved, the problem about stability, consistency and accuracy of TIG manual wire feeding is solved, and the welding line formability and production efficiency are improved.

A welding system includes a welding torch that welds a workpiece by using a wire, a suction device that sucks shielding gas, and a sucked shielding gas supply path for allowing the sucked shielding gas to flow, wherein the welding torch includes a contact chip that guides the wire, a shielding gas supply nozzle that supplies the shielding gas to a weld zone, and a suction nozzle that surrounds a periphery of the wire protruding from the contact chip, and is opened toward a tip of the wire to suck the shielding gas.

A method of welding a wear layer onto a parent material, wherein a welding current is applied to a first wire electrode and to at least one second wire electrode. The first wire electrode and at least one second wire electrode are continuously fed to the parent material for producing a common weld pool. Metal powder and welding powder are fed to the weld pool. The wire electrodes are flux-cored wire electrodes, having a core and a covered electrode. The flux-cored wire electrodes have a higher alloy than a weld deposit analysis of the wear layer to be welded on the parent material. The covered electrode of the flux-cored wire electrodes includes an alloy, which has magnetization properties suitable for adhesion of the metal powder.

Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a metal deposition device (MDD) is configured to deposit a metal material during an additive manufacturing process. A controller is operatively coupled to the MDD and is configured to command the MDD to deposit the metal material on a base to form a contour of a part. The controller is configured to command the MDD to deposit the metal material on the base to form an infill pattern within a region outlined by the contour. The infill pattern is a wave shape having a wavelength. The controller is configured to command the metal deposition device to fuse the infill pattern to the metal contour at crossover points, where the infill pattern meets the contour, by applying energy at the crossover pointsand reducing a deposition rate of the metal material at the crossover points to prevent distorting the contour.
