Coordination of the latest manufacturing technologies to improve aircraft gas turbine combustor design has resulted in developing processes for machining and welding of combustor liners with laser. Major concerns were the cutting and drilling of chrome nickel alloys and ceramics to result in precise sizing with minimal or no burrs or slag which, if they existed, would disrupt airflow patterns, and welding which would neither contribute to distortion nor leave built-in cracks to propagate in fatigue loading. Laser machining has met these criteria with results superior to those of conventional punching, drilling, and welding techniques.
