Development of Laser Beam Delivery and Welding Head for the Inner and Outer Diameter Joints of the AGT 1500 Recuperator

Abstract

The purpose of this TACOM project was to develop and demonstrate a production suitable laser welding head, which could successfully join the plate edges of the inner and outer joints of the AFT 1500 recuperator. This project investigated the laser welding process as a cost effective alternative for the resistance seam welding process currently used in production. The successful implementation of laser hole welder and the production inside diameter/outside diameter resistance welding machine provided background and insight necessary to develop a prototype laser welding head. The project was conducted according to the project plan, which was based on technical tasks and corresponding acceptance criteria. These tasks followed a logical progression toward the development of the prototype welding head. Keywords: AGT 1500 Turbine, Exhaust heat recuperator, Laser welding, Inconel, Inside diameter (ID) joint, Outside diameter (OD) joint.
