Having Variable Welding Head Travel Rate (e.g., Gravity Feed) Patents (Class 219/124.32)
  • Patent number: 11458559
    Abstract: A welding apparatus can comprise an electrode holder configured to removably receive a consumable electrode and an actuator configured to move the electrode holder. The apparatus can comprise a base and an arm having first and second ends, where the first end is coupled to the arm such that the arm extends in a first direction that is angularly disposed relative to the base. The base can be configured to be placed relative to a workpiece such that the second end of the arm is disposed further from the workpiece than is the first end and the electrode, when received by the electrode holder, extends from the electrode holder toward the workpiece. A controller can be configured to adjust a rate at which the actuator moves the electrode holder relative to the arm, optionally based at least in part on an arc voltage measured across the electrode and the workpiece.

  • Patent number: 11407110
    Abstract: Systems and methods for real time feedback and for updating welding instructions for a welding robot in real time is described herein. The data of a workspace that includes a part to be welded can be received via at least one sensor. This data can be transformed into a point cloud data representing a three-dimensional surface of the part. A desired state indicative of a desired position of at least a portion of the welding robot with respect to the part can be identified. An estimated state indicative of an estimated position of at least the portion of the welding robot with respect to the part can be compared to the desired state. The welding instructions can be updated based on the comparison.

  • Patent number: 11260466
    Abstract: Apparatuses, systems, and/or methods for welding systems that provide independent control of a contact tip of a welding torch are disclosed. The welding system can include, for example, a welding torch that includes, for example, a contact tip and a pivot in which the contact tip is coupled to the pivot and is configured to provide wire that is fed through the welding torch during a welding operation. The contact tip and the pivot are configured to independently move the contact tip of the welding torch around the pivot during the welding operation.

  • Patent number: 10464163
    Abstract: This invention discloses a welding equipment for bridges, comprising a base, a fixed ring stand arranged on the top end surface of the base, a fixed block fixedly arranged on the bottom end surface of the fixed ring stand, wherein a first guide sliding groove is arranged in the top end surface of the base, a first guide sliding block in sliding fit connection with said first guide sliding groove. A welding ring stand is fixedly connected to the top end surface of said first guide sliding block; wherein a first adjusting threaded rod is in threaded fit connection with the first guide sliding block. A first motor is in power connection with one tail end of the first adjusting threaded rod. The first motor drives the first adjusting threaded rod to rotate to make the welding ring stand move to one side.

  • Patent number: 10183352
    Abstract: A welding system is disclosed in which the rate of advancement of wire electrode is determined automatically. The device can include a control circuit that determines the rate of advancement of the wire electrode in response to a signal from the voltage selection device of the welding system. Depending upon the operator selected voltage which is selected via the voltage selection device, the control circuit will determine the appropriate rate of wire electrode advancement and control the advancement mechanism (e.g., electric motor) accordingly. Linking of the voltage level and wire-feed speed controls facilities easy of use for more novice operators and, furthermore, facilitates single-handed adjustment of two operational parameters during a welding process.

  • Patent number: 9468987
    Abstract: The present invention provides an arc welding control system and method capable of simultaneously, sophisticatedly performing a weaving width control operation and a torch height control operation. Influence ratios (?w and ?z) of influences of a torch height deviation (?Ph) and a groove wall distance deviation (?Pd) with respect to a manipulated variable (?w) of a weaving width and a manipulated variable (?z) of a torch height are set in accordance with a groove angle (?) of a workpiece (5). A calculation unit (21) calculates the manipulated variables (?z and ?w) of actuators (13 and 14) regarding the torch height and the weaving width such that the influence ratios (?w and ?z) become large as the groove angle (?) becomes large.

  • Patent number: 8901454
    Abstract: In a method for controlling pulse arc welding where an arc is created between a wire and a base material, a pulse waveform different from the pulse waveform for steady-state welding is outputted when a predetermined time has passed since short-circuit welding control was started at arc start, and after a sufficiently large melt pool is formed, the pulse waveform for the steady-state welding is outputted. This reduces the generation of spatters after an arc is created and until the arc is stabilized.

  • Patent number: 8742291
    Abstract: A method of controlling arc welding, which method shifting the speed of welding operation continuously and mildly. By so doing, a sharp change in the speed of weld wire supply, which is caused as the result of efforts to try to comply with an abrupt change in operation speed, can be moderated. This helps keeping a welding operation under a stable control.
