Statistical analysis of weld repair length in aerospace pressure vessels
Welding is a governing process in realization of aerospace pressure vessels. In defence and aerospace industry, ultrahigh strength materials viz maragingsteel is being used for realization to meet the mission requirements. The fracture based design is adopted for pressure vessels. The quality of welding is ensured by qualifying the welding process, through procedure qualification, use of qualified welders and Non-destructive testing. Weld joints are inspected using Non destructive testing such as Radiography testing, Ultrasonic testing, Die penetrant testing etc.
