As the development of science and technology, what material studies is ceaseless and thorough, excel in aluminium alloy applies on spacecraft component more and more extensive, box of spacecraft fuel lay aside is among them one of typical member. But the extreme difference of weldability of fusion welding of excel in aluminium alloy of 2000 series, 7000 series, how to join become the main problem that puzzles project technology personnel. Boeing company and England solder the institute cooperates, used technology of agitate friction welding successfully to solve the join problem in the project. Intermediate cabin paragraph the Delta II rocket that join uses technology of agitate friction welding blasts off at succeeding on August 17, 1999, use at at succeeding on April 7, 2001 locomotive " spark pokes number " , this second blasts off also is technology of agitate friction welding applies at pressure vessel first, use temperature of job of box of lay aside of fuel of connective of technology of agitate friction welding to be - 195 to ＋ 183 Celsius. The factory of Boeing company Alabama uses technology of agitate friction welding, aid push cabin paragraph solder contact intensity raised 30 ％ - 50 ％ , production cost dropped 60 ％ , production cycle decreases by 23 days to 6 days. Release the day of this information up to TWI, the agitate attrition welding line that uses at Delta II rocket already amounted to 2100 meters, application already amounted to 1200 meters at welding line of attrition of agitate of Delta IV rocket, without any blemish. Use case of lay aside of fuel of Delta II of connective of agitate friction welding rocket sectional use box of lay aside of fuel of spaceflight of Delta II of connective of agitate friction welding rocket to use case of lay aside of fuel of spaceflight of Delta IV of connective of agitate friction welding rocket CNC Milling CNC Machining
