A welding-type system includes a welding-type power supply configured to generate output power for an arc welding process and a controller. The controller calculates a representative duration of a plurality of short circuit events and/or arc events during the arc welding process. Each short circuit event and/or arc event comprises a transitional phase, an intermediate phase, and an end phase. The controller calculates a sum of a duration of the transitional phase, a duration of the intermediate phase, and a duration of a ramp down time from a target current of the intermediate phase to a target current of the end phase associated with a given short circuit or arc event. The controller controls the welding-type power supply to adjust a duration of the transitional phase, the intermediate phase or the ramp down time associated with the given short circuit event such that the sum is within the threshold range of the representative duration. Additionally or alternatively, the controller maintain a duration of the end phase less than a predetermined value.

Systems and methods for controlled arc and short phase time adjustment

A welding system includes a first sensor associated with a welding helmet and configured to sense a parameter indicative of a position of a welding torch relative to the welding helmet. The travel speed sensing system also includes a processing system communicatively coupled to the first sensor and configured to determine a position of the welding torch relative to a workpiece based on the sensed first parameter.

Helmet-integrated weld travel speed sensing system and method

Disclosed is a welding system configured to perform additive manufacturing, particularly a welding system to achieve a stable a laser metal deposition with hot wire process by controlling the contact point between the welding wire and the workpiece. For example, the resistance of the stick-out wire is measured and the measured resistance is converted to a distance signal, which can then be used for comparison to a desired distance. The distance between the contact tip and the workpiece can then be adjusted based on the comparison. The present disclosure also relates to using a constant enthalpy system to determine and control the contact tip to workpiece distance.

Systems and methods for height control in laser metal deposition

Disclosed is a welding system configured to perform additive manufacturing using a controlled short circuit welding process to apply a plurality of droplets of a wire to create a multilayer part comprised of the droplets. Operational parameters of the additive manufacturing system are dynamically adjusted based on data representing a temperature value and/or a geometric characteristic of the part. Based on the data, the controller can adjust one or more operational parameters to control application of droplets to build up the part.

Systems and methods for additive manufacturing in a controlled short circuit welding system

A method and apparatus for controlling arc/short between a wire and a work piece is described. A current path parallel to the wire/work is provided. The voltage drop across the parallel path can be preset, to limit the wire/work voltage, or it can be controlled to a desired level. The control can be in response to feedback.

Welding system with arc control

A travel speed sensing system includes an optical sensor configured to be coupled to a welding torch. The optical sensor is configured to sense light incident on the optical sensor, and the travel speed sensing system is configured to determine a travel speed of the welding torch, a direction of the welding torch, or both, based on the sensed light.

Optical-based weld travel speed sensing system

Methods and apparatus to provide a consistent electrode state for welding, an example welding-type system includes: a first wire drive to feed an electrode wire through a welding torch; a bidirectional assisting wire drive to advance the electrode wire from a wire supply to the first wire drive; a tension-compression detector to detect a first tension-compression state of the electrode wire; and one or more motor controllers to control the first wire drive and the assisting wire drive to put the electrode wire in a predetermined position relative to the welding torch by: controlling the first wire drive to hold the electrode wire; and controlling the assisting wire drive to advance or retract the electrode wire based on the first tension-compression state to put the electrode wire in a second tension-compression state.

Methods and apparatus to provide a consistent electrode state for welding

Disclosed welding-type systems and methods are directed to employing a wire feeder for feeding an electrode wire from a wire source in a welding system. The wire feeder includes one or more drive rolls to advance the electrode wire by contact force. In disclosed examples, a contact force on the wire from the drive rolls is adjustable. In some examples, the system includes a controller to receive a feedback signal corresponding to the contact force. The controller commands an actuator or other mechanism to adjust the contact force on the wire, such as by adjusting a position of the one or more drive rolls in response to the contact force falling outside a range of threshold contact force values.

Systems and methods for controlling drive roll contact force in welding-type systems

Disclosed welding-type systems include a welding-type power source to generate output power for a periodic welding process that operates in an arc mode, an open circuit mode or a short circuit mode. A wire-feeder advances an electrode wire toward a workpiece. A controller adjusts the current to below a threshold value during the arc mode to result in the open circuit mode prior to occurrence of a short circuit event based on one or more welding process parameters. In some examples, the controller determines the occurrence of the short circuit event based on the one or more welding process parameters, and adjusts the current to rise above a second threshold level to adjust a heat generated in the welding wire in response to the occurrence of the short circuit.

Systems and methods for controlling heat input during short-circuiting type welding processes

A welding system or an enterprise using welding systems can communicate with cloud-based resources for the provision of services and products to facilitate the welding operations. The communications may be via wired or wireless media, and may be direct, or through other components, such as enterprise networks, peripheral devices, and so forth. The cloud-based resources may provide for storage of data, particularly welding data, processing of data, welding protocols, specifications and processes, financial transactions for the purchase, licensing or use of welding-related products and services, welding training, and so forth.

Method for determining Arc consistency in pulsed gas metal Arc welding systems

A welding method includes feeding a welding electrode axially from a welding torch, moving the welding electrode radially in a desired pattern with respect to a central axis of the welding torch by a motion control assembly within the welding torch, transmitting from control circuitry a signal corresponding to a position of the welding electrode relative to a weld joint or weld pool, advancing the welding torch or a workpiece to establish a weld, and transferring material from the welding electrode to a first location in an area of the weld pool. The welding electrode moves radially while feeding the welding electrode from the welding torch, the material from the welding electrode is transferred to the first location during a first cycle of the desired pattern, and the first location is controlled based at least in part on the signal.

Synchronized rotating arc welding method and system

A method for monitoring a spatter generating event during a welding application. The method includes capturing data that corresponds to a welding current of the welding application. The method also includes detecting parameters associated with a short circuit from the captured data. The method includes analyzing the detected parameters to monitor the spatter generating event during the welding application.
