Embodiments of systems and methods for supporting weld quality across a manufacturing environment are disclosed. One embodiment includes manufacturing cells within a manufacturing environment, where each manufacturing cell includes a cell controller and welding equipment. A communication network supports data communications between a central controller and the cell controller of each of the manufacturing cells. The central controller collects actual weld parameter data from the cell controller of each manufacturing cell, via the communication network, to form aggregated weld parameter data for a same type of workpiece being welded in each of the manufacturing cells. The central controller analyzes the aggregated weld parameter data to generate updated weld settings. The updated weld settings are communicated from the central controller to the cell controller of each of the manufacturing cells via the communication network.

Embodiments of systems and methods for supporting predictive and preventative maintenance are disclosed. One embodiment includes manufacturing cells within a manufacturing environment, where each manufacturing cell includes a cell controller and welding equipment, cutting equipment, and/or additive manufacturing equipment. A communication network supports data communications between a central controller and the cell controller of each of the manufacturing cells. The central controller collects cell data from the cell controller of each of the manufacturing cells, via the communication network. The cell data is related to the operation, performance, and/or servicing of a same component type of each of the manufacturing cells to form a set of aggregated cell data for the component type. The central controller also analyzes the set of aggregated cell data to generate a predictive model related to future maintenance of the component type.

To provide an arc welding robot system that displays a current waveform graphically during arc welding and realizes parameter adjustment on a display screen. An arc welding robot system comprises a robot controller and a teaching operation terminal. The robot controller comprises: an arc sensor; and a welding current storage unit that stores the current value of a welding current detected by the arc sensor during implementation of the arc welding. The teaching operation terminal comprises: a control unit; and a display on which data is displayed. The control unit comprises: a welding current display unit that displays the current value and the waveform of the welding current in any weaving cycle on the display; a sampling current area display unit that displays a sampling current area on the display; and a current waveform display shift unit that shifts the waveform of the welding current in a temporal axis direction on the display unit.

A welding system includes a power supply configured to output a series of welding waveforms for generating a welding current in a consumable welding electrode, and a wire feeder that advances the electrode toward a weld puddle during a welding operation. The wire feeder includes a subcircuit having a switching device and parallel resistance, the subcircuit being connected in series with the electrode such that the welding current flows through the subcircuit. The switching device is controllable between conducting and nonconducting states. The wire feeder includes a controller operatively connected to the switching device that controls switching operations of the switching device. The power supply is configured to remotely identify occurrences of the switching operations in the wire feeder and control the welding waveforms based on the occurrences of the switching operations.
