Aerospace Industry
Welding systems for gas turbines and rocket engine components
The aerospace industry was the first to recognize the necessity for automated orbital welding. Critical fuel and hydraulic control lines are exposed to extreme cyclical mechanical and thermal stresses. This led to a search for a more reliable joining technology to replace mechanical fittings. For over four decades, we have provided specialized automated orbital welding systems to manufacturers and component suppliers for turbine engine fabrication. Orbital welding is a key technology used by specialized providers of aerospace welding services for component repair and overhaul.
Currently, a single aircraft's high-pressure systems can contain more than 1,500 joints. All of these joints have been welded using automated orbital welding equipment. The precise control of heat input by orbital welding is critical to prevent distortion.
- Digital control of the welding process ensures perfect, repeatable welds required by aerospace welding standards.
- Magnatech orbital welders incorporate weld monitoring and QC reporting for each weld made.
- Autoprogramming automatically generates weld parameters, simplifying operator training
Magnatech serves the aerospace welding industry with a range of models and capabilities. We provide operator training, timely service and technical assistance to our customers worldwide.
Applications
Turbine Engine Component Fabrication
Equipment Used
Challenge
A New England-based precision manufacturer of aircraft engine components received a large order from Rolls Royce that required making welds on critical 1" OD hydraulic lines to aerospace-quality standards (AS 7003, and 9100 Rev. B).
Solution
Magnatech was awarded the order in competition with two other vendors based on ease of programming and reputation for support. The manufacturer subsequently purchased additional equipment to support two 8-hour/shifts per day operation.
Challenge
Hong Kong Engineering Company Ltd., better known as HAECO (a SWIRE Group company) provides comprehensive aeronautical engineering and maintenance services - in Hong Kong, as well as other Chinese cities, and also operates facilities in Bahrain and Singapore. One task is the component overhaul and replacement of small diameter stainless fuel lines which surround the engine casing. These small tubes cannot be practically welded manually.
Solution
Magnatech supplied a Tubemaster power source and enclosed Head to make these precision welds.
Weld QC reports can be printed out following completion of each weld.
