The evolution of modern superalloys has coincided with the evolution of the gas turbine for the aviation industry. The rate of development of new alloys has been rapid and, in many ways, exceeded his companion in developing editing techniques. Traditionally, the focus in the development of alloys has been on resistance to high temperatures, the properties of creep and oxidation. Participate in the metal has been treated as a separate problem by welding and brazing engineers were generally required to develop procedures and techniques to reach each league again after it was developed. This has resulted in excessive costs of production for some alloys due to changes in the problems that cause such unpredictable and uncontrolled metallurgical cracking during welding. Titanium is often preferred for welded aviation.
Despite the many difficulties, welding has been and will continue to be one of the leading manufacturing techniques and components of aircraft engines on the ground. Welding possible to produce sub-economic, with virtually no extra weight and low cost. Welded joints cause a reduction in service capacity are placed in a relatively short non-critical areas. titanium pipe
