Space welding temperature requirements

650℃。 When the aerospace welding temperature is lower than 650℃, the alloy has high strength, good cold and hot fatigue properties, weldability and high pressure hydrogen embrittlement resistance. Welding technology mainly uses heat and pressure to combine atoms of same-sex or different-sex workpieces, so as to complete the processing of parts and the connection of workpieces. In aerospace industry, the use of welding technology can not only improve the performance of spacecraft engine, but also reduce the quality of spacecraft. At present, various welding technologies have been adopted in the manufacturing process of aerospace industry.
