An example welding system includes a power supply configured to output welding power; a weld parameter feedback sensor configured to produce a weld feedback parameter corresponding to an actual weld condition during welding; and a welding program comprising: a first weld having first weld parameters; a second weld having second weld parameters, wherein the second weld follows the first weld; a controller configured to, in response to selection of the weld program for performing a welding job on a part: control the power supply to provide the welding power to a first weld operation based the first weld parameters; monitor first feedback from the power supply; control the power supply to provide the welding power to a second weld operation based the second weld parameters; monitor second feedback from the power supply; and determine whether at least one of the welding job or the part is acceptable.

Automatic weld arc monitoring system

A welding system includes a repositionable temperature sensor. The repositionable temperature sensor is configured to detect temperatures corresponding to a workpiece and to provide temperature data corresponding to the detected temperatures. The welding system also includes a power supply configured to receive the temperature data from the temperature sensor. The power supply is configured to modify control of an output of the power supply based on the detected temperature.

Welding system for determining a quality of a welding operation

A welding system including an arc monitoring, training, and control system is disclosed. The welding system includes a power supply, controller, and associated memory. When a weld is performed, the weld command and weld feedback parameters can be stored in the memory, along with associated alarm limit values. During subsequent welds, the input weld commands and actual feedback values can be compared to the established limits, and a fault signal provided to an operator or supervisor when the value exceeds the established limits. The fault signals can be used for training operators, as well as providing monitoring signals, and can be stored with weld data in a database for later analysis. In addition, collected weld data can be used to determine when to clean, repair, or replace consumables, including, for example, contact tips, wire drive liners, and drive rolls, and to monitor usage of wire and gas.

A method and apparatus for automatic or hand held welding is disclosed and includes a power circuit with a controller. The controller has a robot detector. A hand-held module and a robot interface are responsive to the robot detector. A user interface provides welding parameter setpoints to the hand held module when the robot detector detects a gun, or the absence of a robot. When a gun is present, the trigger on the gun is used to cause power to be provided, and/or welding parameters are set by the user interface on the system. When a robot is present the robot controls the process. The detection is done at start-up, or at other times.
