Abstract: Systems and methods for laser welding are disclosed. A laser welding system employs a beacon to indicate laser welding will or has commenced. The beacon emits an intense light in a visible spectrum, such that a filter or lens is needed to block the intensity of the light.

Abstract: A method and apparatus for monitoring weld cell and related activity is disclosed. The activity is sensed using a variety of sensors, and reported to the controller, or to a remote location.

Abstract: Systems and methods for laser welding are disclosed. A laser welding system includes a manually operated laser welding torch to direct laser power to a workpiece to generate a puddle during a laser welding operation. The welding system includes a controller to regulate activation and regulation of the laser power based on user inputs, sensor inputs, and/or synergic control of a laser power source.

Abstract: A method and apparatus for providing welding-type power is disclosed and includes a means for communicating and a means for locating a cable. A welding power supply has a controller, a power circuit and a weld cable locator module with a cable locator output connected to the controller, the power circuit, and/or a weld cable connection. The distal end of the cable is located, and the proximal end is connected to the power supply. An identifying signal is provided to the proximal end and transmitted to the distal end where it is detected. A pendant with a cable sensor and a transmitter responsive to the cable sensor can be provided. The cable sensor can include an RFID reader and/or a bar code reader.

Abstract: A method and apparatus for welding include initiating a pulse welding process includes initiating a welding arc by providing CC type welding power, maintaining the arc by providing CV type power. Then, pulse type welding power is provided. The method and system can be used to start short circuit, or other welding processes by providing short circuit power, or welding power of a given mode, instead of providing pulse power. Also, in one alternative, a method and system of initiating a pulse, short circuit, or given welding process includes initiating a welding arc by providing CC type welding power at least until a pseudo-equilibrium for the arc is established. Then, providing welding power in a pulse, short circuit, or the given mode.

Abstract: A method and apparatus for welding is disclosed. The output is preferably a cyclical CV MIG output, and each cycle is divided into segments. An output parameter is sampled a plurality of times within one or more of the segments. The CV output is controlled within the at least one segment in response to the sampling. The parameter is output power, a resistance of the load, an output current, an output voltage, or functions thereof in various embodiments. The control loop is preferably a PI or PID loop. The loop may be applied only within a window. The set point may be taught or fixed. The system can be used to weld with a controlled arc length.
