Abstract:
This is a state-of-the-art report on weldable tube fittings, welding equipment and inspection methods for connecting tubing in aerospace/aircraft hydraulic systems.

Design advantages and limitations of several types of fittings, including a new swaged-on concept, are discussed. Initial flexure-endurance tests of the new design indicate greater than a 30-fold improvement.

Tungsten inert gas welding equipment utilizing an orbital type welding head with automatically programmed time, current and gear speed, provides remote in-place welding capability.

Nondestructive radiographic and ultrasonic inspection methods are also described.
