摘要:
A welding or cutting device includes an internal combustion engine coupled to a generator for generating electrical power. A welding or cutting power supply is powered by the generator. The welding or cutting power supply supplies a welding or cutting output signal. An auxiliary outlet circuit is configured to receive power from the generator. The auxiliary outlet circuit includes at least one auxiliary load outlet. A controller controls an engine speed of the internal combustion engine. The controller is configured to determine an anticipated load on the generator to be supplied through the auxiliary load outlet, based on a no load condition of the auxiliary load outlet, and adjust an idle speed of the engine based on the anticipated load. The controller is further configured to subsequently increase the engine speed, from the idle speed to an auxiliary load speed, when the generator supplies power through the auxiliary load outlet.

摘要:
Systems and methods for facilitating the starting and stopping of arc welding processes, as well as for responding to events in mid-weld. Specially designed signals may be briefly applied between a welding electrode and a welding workpiece at the start and end of a welding process to gracefully and properly start and stop a weld. Furthermore, specially designed signals may be briefly applied in the middle of a welding process, if determined events occur, to counter the undesirable effects of the events.

摘要:
Systems and methods consistent with embodiments of the present invention are directed to depositing a consumable onto a workpiece using a hot-wire welding technique which employs a combination of hot wire and arc welding. The waveform creates arc events during the hot wire welding operation to add/control heat in the welding process. The hot-wire welding process can be used by itself, with a laser or in conjunction with other welding processes.

摘要:
To start consumable electrode arc welding, an initial current is supplied to a welding wire after causing the welding wire to contact a base material and retracting the welding wire from the base material. Thereby, an initial arc is generated. The welding wire is retracted continuously for an initial arc lift period Ti with the initial arc maintained. Afterwards, the initial arc is switched to a steady arc. A predetermined weld pool formation period Tp is set after the initial arc lift period Ti. In the weld pool formation period, a weld pool formation current greater than the initial current is supplied with the initial arc maintained and the welding wire is caused to proceed and fed to the base material. In the weld pool formation period, a weld pool is formed by the initial arc without allowing the welding wire to release droplets and contact the base material.
摘要:
In a method for controlling pulse arc welding where an arc is created between a wire and a base material, a pulse waveform different from the pulse waveform for steady-state welding is outputted when a predetermined time has passed since short-circuit welding control was started at arc start, and after a sufficiently large melt pool is formed, the pulse waveform for the steady-state welding is outputted. This reduces the generation of spatters after an arc is created and until the arc is stabilized.
摘要:
A welding control method alternately repeats a short circuit period, during which a welding wire and an object to be welded short-circuit, and an arc period, during which an arc is generated and discharged, to weld the object to be welded. The method compares average output voltage, which is an average of welding voltage calculated during welding, to set voltage preliminarily set, and controls a welding output current produced when an arc is generated based on the comparison result therefrom, to regulate the meltage of the wire for adjusting the arc length, which brings the short circuit cycle closer to a constant one when a disturbance (e.g. extended or shortened arc length) occurs.
摘要:
A robot welding controller and a robot welding control. It comprises a robot having a welding torch at its tip, a robot controller, a wire feeder, and a welding electric power. It performs welding by moving the welding torch on the basis of a commanded welding line. A contact detecting section detects contact of the wire and the base material. A feed direction switching section switches feed directions of the wire. An arc generation detecting section detects that an arc is generated between the wire and the base material. A waveform control section controls electric power waveforms of plural shapes applied between the wire and the base material. A welding sequence section controls the operations of the contact detecting section, the feed direction switching section, the arc generation detecting section and the waveform control section in block.
