International Classification:

B23K 9/09
B23K 9/10
B23K 9/095

Abstract:

Embodiments of welding systems and methods for reducing spatter in pulsed welding are disclosed. A welding power source includes a first welding output stud to be electrically connected to a consumable welding electrode and a second welding output stud to be electrically connected to a workpiece. Power electronics generate welding output current pulses. A switching network is connected between the power electronics and the first welding output stud. A controller is connected between the power electronics and the switching network. The controller controls the timing of each welding output current pulse and switches the switching network back and forth between a first welding output current flowing state and a second welding output current impeding state based on the timing. An increase in a decay rate of a trailing edge of each welding output current pulse is effected during the second welding output current impeding state.

Abstract:

A welding or additive manufacturing system includes a contact tip assembly having first and second exit orifices. A wire feeder is configured to deliver a first and second wire electrodes through the exit orifices. An arc generation power supply is configured to output a current waveform to the wire electrodes simultaneously, through the contact tip assembly. The current waveform includes a bridging current portion, and a background current portion having a lower current level than the bridging current portion. The bridging current portion has a current level sufficient to form a bridge droplet between the wire electrodes before the bridge droplet is transferred to a molten puddle during a deposition operation. Solid portions of the wire electrodes do not contact each other during the deposition operation. The bridge droplet is transferred to the molten puddle during a short circuit event between the molten puddle and the wire electrodes.

International Classification:

B23K 9/09
B23K 9/10
B23K 9/095

Abstract:

A system for controlling arc length by regulating short circuit events during a welding process includes a welding power supply configured to conduct a free flight transfer pulsed arc welding process between a welding electrode and a workpiece, and a controller operatively connected to the welding power supply to control a welding waveform of the free flight transfer pulsed arc welding process. The controller is configured to automatically determine whether or not tethered incipient short circuits are included in said welding waveform, monitor a short circuit event characteristic during the free flight transfer pulsed arc welding process, and automatically adjust, based on said short circuit event characteristic, at least one parameter of said welding waveform to regulate tethered incipient short circuiting of the welding electrode to the workpiece during the free flight transfer pulsed arc welding process after determining that tethered incipient short circuits are included in said welding waveform.

Abstract:

The invention described herein generally pertains to a system and method related to reducing magnetic arc blow during a welding operation performed by a welding system. In accordance with one embodiment of the invention, a welding system including a waveform generator generates a waveform that is switched from a positive current to a negative current, while passing through zero, in a step-wise fashion to resist the magnetic field within the material (e.g., the workpiece). In accordance of another embodiment of the invention, the welding system includes a nickel flux cord welding wire.
