Embodiments of brazing systems are disclosed. In one embodiment, a brazing system (100) includes a controller circuit board (controller) (260) having a processor (264) and a memory (262). The system also includes a fuel gas input (222), a fuel gas output (224), an oxygen/air gas input (216), and an oxygen/air gas output (218). The system further includes a touch screen display (202) and a foot pedal (610), each operatively connected to the controller (260). The controller (260) is configured to store multiple jobs of flame presets in the memory (262). Any job can be called up from the controller (260) and the flame presets can be cycled through in response to tapping the foot pedal (610). Each job corresponds to a sequence of joint brazings to be performed on a braze assembly and includes a plurality of selectable flame presets. Each flame preset defines a flame setting based on a flow rate of a fuel gas and a flow rate of an oxygen/air gas.

A laser welding gun includes a focal tube, a nozzle extending from the focal tube, and a mounting armature adjustably positionable along a length of the focal tube. A conduit assembly extends from a wire feeder and is attached to the focal tube by the mounting armature. The conduit assembly includes a removable tip holder secured to the mounting armature. The mounting armature provides adjustment of an angle between the conduit assembly and the focal tube, and an orientation of the mounting armature is rotationally adjustable around a circumference of the focal tube.

A control system for a material processing application includes a sensor device and a controller. The sensor device is configured to receive actual motion data and actual process data from equipment performing the material processing application. The controller includes logic to determine adjusted motion parameters and adjusted process parameters based on the actual motion data and the actual process data, and execute the adjusted motion parameters and the adjusted process parameters to achieve a performance target.

A brazing system includes a first brazing torch, a second brazing torch, a third brazing torch, a torch carriage having an actuator system configured to rotate the first brazing torch, the second brazing torch, and the third brazing torch simultaneously from a substantially vertical orientation to a substantially horizontal operation, and a mass flow controller configured to control respective flows of gas to each of the first brazing torch, the second brazing torch, and the third brazing torch. The mass flow controller controls the respective flows of gas based on either a first heating profile for making a single brazed connection using two of the first brazing torch, the second brazing torch, and the third brazing torch, and a second heating profile for making two brazed connections simultaneously using each of the first brazing torch, the second brazing torch, and the third brazing torch.

A method of mitigating arcing events in a hot wire process is provided. The method includes monitoring an arcing frequency of a hot wire process and monitoring at least one of an energy, a power, a deposition amount, or a deposition rate of the hot wire process. The method further includes adjusting at least one of a hot wire current, a hot wire voltage, a hot wire waveform characteristic, a wire feed speed, a wire approach angle, or a contact tip-to-work distance of the hot wire process to balance the arcing frequency against at least one of the energy, the power, the deposition amount, or the deposition rate of the hot wire process, where it is desirable for the arcing frequency to be low, and where it is desirable for the energy, the power, the deposition amount, or the deposition rate to be high.

A welding system includes a collaborative robot, a robot controller, a welding torch having an end located at a tool center point (TCP), a welding power supply, and a teach pendant. The teach pendant includes a UI application configured for programming welding points and parameters. In a first operation mode, the UI application displays the plurality of welding points in a list that includes a highlighted closest welding point having a three-dimensional position that is closest to the TCP. The highlighted closest welding point automatically updates upon manual movement TCP. In a second operation mode, the list includes a highlighted selected welding point, and the UI further displays a selector button that shows a straight line distance of the TCP to a three-dimensional position of the highlighted selected welding point. Activation of the selector button causes the TCP to move to the position of the highlighted selected welding point.
