Abstract: The invention relates to the field of automated welding, and more particularly, to an automated, gas metal arc welding apparatus for externally welding abutting sections of pipe. The apparatus has a motorized main carriage for travelling circumferentially about one of the pipe sections to be welded. The apparatus is provided with a welding torch which is connected to the main carriage. The welding torch is movable relative to the main carriage by the actuation of a multi-axis drive mechanism. The multi-axis drive mechanism has a horizontal transport mechanism for linearly translating the torch transversely of the weld seam, a vertical transport mechanism for vertically displacing the torch transversely of the weld seam and an angular transport mechanism for pivotally moving the torch transversely of the weld seam. A controller is provided for actuating the various transport mechanisms individually or simultaneously if desired.

Abstract: A mobile automated pipeline welding and quality control system comprising a gas metal arc welding carriage and a weld data monitor and acquisition unit. The welding carriage carries a welding torch, wire feed device for feeding consumable wire to the torch, an oscillator for oscillating the torch and a motorized drive mechanism for moving the carriage about a weldment. A controller for the carriage includes digital control circuitry for dosed loop control of the drive, oscillator and wire feed devices. By default, the controller operates each device at one of a plurality of pre-programmed nominal speeds selected from a mode table. The controller is responsive to drive, oscillation and wire feed speed variation signals under the control of an operator, and varies the speed of each device within speed ranges which are selected to ensure compliance with welding specifications. The monitor has voltage and current transducers for measuring current and voltage at the welding torch. The controller supplies the monitor with speed data relating to the drive, oscillator and wire feed devices. All of this information can be displayed and recorded in the monitors memory. In addition, the monitor can compute and display the heat input into the weld based on the detected welding parameters. This information allows the operator to make minute adjustments during the welding process to ensure that a weld falls within specifications.
