    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.

    Abstract: Improved welding method and padeye processing speeds up the connection of individual joints by peripheral fusion welding while the joint to be added stands vertically atop an existing pipe string also standing vertical in the rig floor. A plurality of welders can operate to speed up completion of the weld by removing heat from the pipe during the welding process. Heat is removed by the use of fluid cuffs near the weld area and, optionally, by using a spool within the pipe string to dispense expansion cooled air against the inner pipe wall in the vicinity of the weld. A special improved padeye is provided for welding near the pipe ends for handling. The padeye has a divided profile, a hole for a lifting shackle, and it will be accepted within the skirt of the lead system of the driving hammer. The upper end of the padeye can be cut from the pipe while the pipe is resting, on rig related structure, on the lower surface of the padeye.

    Abstract: An apparatus method for pipe end preparation and end to end welding of pipes comprises a stationary annular clamp (4) for both clamping and round up of pipes (2). It also has one or two rotating tool carrier rings (5) mounted at one or both sides of the clamp (4) on a track (6). The rotating ring may have thereon devices for cutting, machining of grooves, welding and non-destructive testing (NDT). The round up of the pipe is performed via 6 or more clamping shoes independently operated by screw jacks (18), a wedge mechanism (15) or directly acting hydraulic cylinders.
