The Boiler Automated Welding System (BAWS) is an automatic welding system for repair of worn boiler tubes in cyclone boilers. Repair of these tubes is essential for extending the life of this component used within electrical power plants. The BAWS utilizes: 1) a multiaxis positioner which forms the required cylindrical coordinate motion system, 2) a tube tracking systems for determination of motion paths during welding, 3) a two axis gimbaled welding torch holder for orientation of the welds relative to the motion path, 4) an integrated welding system and 5) a computer controller which coordinates these devices in a logical method.The BAWS multiaxis positioner allows for orientation of the system within the cyclone boiler to take advantage of the symmetry of the tube layout (cylindrical coordinates). The positioner allows each individual tube to be scanned and a weld path determined using a laser scanning device. This information is then processed through the computer which coordinates the multiaxis positioner, welding system, and gimbaled torch holder to place a weld bead upon the scanned tube. This process is repeated systematically until the surface of one tube is covered with new weld metal. The entire sequence is then repeated on adjacent boiler tubes until the cyclone boiler unit is completed.
