• Abstract:
  The construction cost of large welded pipeline systems can represent half the project expenditures, and in many instances the welding costs are a major component. The control or reduction of these costs and rework to eliminate weld faults has been the focus of productivity enhancement efforts across a wide range of industries. To this end, laboratory research has investigated and made use of a number of technologies to improve weld quality and efficiency and facilitate inspection including: - The use of lasers for cutting and joining of plate elements, in particular Hybrid Laser Arc Welding (HLAW) systems; - Robotic systems with seam tracking technology to automate and control high speed welding processes; and - Automated Laser Ultrasonic Inspection (ALUT) to detect, size, characterize, and assess the significance of weld defects at high speed and document the inspection results.
