ORBITAL WELD PERMANENT FITTING

Transcription

1 ORBITAL WELD PERMANENT FITTING DESIGN CONCEPT: Weld fitting design offers smallest envelope, lightest weight and strongest joint among all other mechanical fitting joints. Navy test results showed an average welded joint has a durable fatigue life up to 50% higher than mechanically attached fitting joints. No wonder this concept is widely used in commercial and military programs worldwide. The weld fitting end design has the simplest geometrical contour with an integral T-ring. It provides alignment for the fitting and tubing and is also a filler material for welding. Fitting and tubing ends shall be cleaned prior to welding; one of the simplest cleaning methods is to spray acetone to the joint and it will quickly evaporate. Weld fittings are easily to be welded by Orbital weld tooling with electronic memories to reproduce accurate repeated weld each time. It minimizes X-ray inspection to a large degree. Different tooling is available for bench production weld or portable welding. The unified welded joint provides a positive fluid sealing. DESIGN ADVANTAGES: Unified weld joint offers positive sealing. Offers smallest envelope, lightest weight and strongest fitting joint. Electronic memories produce accurate repeated weld each time. Weld tooling requires lowest maintenance cost by replacing tungsten only. Integral T-ring offers self-alignment for fitting and tubing butting to support proper welding.

2 STANDARD PROCUREMENT SPECIFICATIONS FOR ORBITAL WELD FITTINGS SAE AS576 and/or AS59 specifications define Form, Fit, Function and Procurement requirements for Orbital Tube Weld fittings. QUALIFICATION AND APPROVAL STATUS Airdrome fittings were tested per SAE AS576 and AS59, Boeing 7M07 and BPS-F-5, Lockheed 5PTV50 and Northrop 7A050 specifications. The fittings are approved for use in various space, military, and commercial programs at Allison, Bell, Boeing, Commercial/Defense/Space Group, General Electric, Honeywell, Lockheed, Northrop/Grumman, Sikorsky, etc. TOOLING Various welding equipment manufacturers offer Orbital Weld tooling and training.
