摘要： The invention relates to an electric arc-welding welding head comprising a contact device and one or more wire feeder units, the contact device encompassing an electrode assembly, the electrode assembly comprising at least two fusible continuously-fed wire electrodes arranged in a contact device. An electrically insulated duct is provided for electric insulation of at least one of the electrodes so that the electrode is electrically insulated from other electrodes in the electrode assembly. The invention also relates to an electric arc-welding contact device and an electric arc-welding welding head assembly.

摘要： A method and system for electroslag strip cladding (ESSC) of rail heads without preheating utilizing twin electroslag strip welding techniques. The twin ESSC techniques include depositing a layer of wear and corrosion resistance cladding material onto the entire running surface of the rail head at a relatively fast welding speed of approximately sixty cm/minute with less than one cm/meter of distortion. The welding speed is achieved by moving a twin ESSC welding head along a rail, with the running surface of the rail head facing upward, or advancing a rail through a space under the twin ESSC welding head, with the running surface of the rail head facing upward, while cladding material is deposited continuously onto the running surface of the rail head.

摘要： A pistol grip for a processing torch is disclosed. The pistol grip includes a main body having a proximal end and a distal end, a pistol trigger having a trigger extension, and a locking mechanism movably coupled to the main body adjacent the proximal end of the main body. The proximal end may be configured to engage a portion of the processing torch. The pistol trigger may be pivotably coupled to the main body. The locking mechanism may be movable between an unlocked position and a locked position where the locking mechanism locks the main body in a fixed position with respect to the processing torch.

摘要： An apparatus to provide welding power. The apparatus may include a direct current-alternate current (DC-AC) power converter to output a primary current and a transformer stage. The transformer stage may include at least one power transformer to receive the primary current from the (DC-AC) power converter on a primary side of the transformer stage and to output a first voltage through a first rectifier and a first set of secondary windings disposed on a secondary side of the transformer stage. The transformer stage may further include an auxiliary set of secondary windings disposed on the secondary side to output a second voltage. The apparatus may also include a pair of active unidirectional switches disposed on the secondary side to receive the second voltage from the auxiliary set of secondary windings.

摘要： A method of operating a welding power supply during a welding process in which an electric arc between a consumable electrode and a work piece is generated while feeding the consumable electrode and moving the arc in relation to the work piece along a welding track, wherein a transition between a DC power output of the welding power supply and an AC power output of the welding power supply, or vice versa, is made without interruption of the welding process.

摘要： An automated welding system includes a support structure, a plurality of welding heads, and a controller. The plurality of welding heads are each removably, mechanically coupleable to the support structure. The controller is configured to control welding operations of the automated welding system based on an identity of a particular welding head of the plurality of welding heads that is mechanically coupled to the support structure and operably coupled to the controller.

摘要： The present invention refers to a control method and welding equipment for MIG/MAG-welding with presence of short-circuiting droplets between an electrode end and a workpiece. The method comprises establishment of a short-circuiting time, establishment of an arc time, and controlling the energy supplied to the electrode. The energy supply is controlled in such a way that the energy supply is increased if a measured short-circuiting time of a total period time, where the period time is the sum of the short-circuiting time and the arc time, exceeds a defined adjustable set value and decreases if said short-circuiting percentage goes below said set value.

摘要： A method includes monitoring a submerged arc welding (SAW) operation in real-time; determining, based on the monitoring and in real-time, a discrepancy between a desired weld parameter and an actual weld parameter of a weld resulting from the SAW operation; and in response to determining the discrepancy, controlling a power supply, which provides power for the SAW operation, to modify at least one of balance or offset of an alternating current (AC) welding power signal supplied for the SAW operation to compensate for the discrepancy.
