- 摘要:
- 对球形表面张力贮箱装配精度与表面张力贮箱焊缝熔深及形貌之间的关系进行了研究，得到了电子束焊接工艺规范。该规范为：采用虚焦电子束焊接工艺，聚焦束流虚焦30 mA，焊缝锁底部位宽度0.7 mm，焊接束流23 mA，焊接速度1 200 mm/min，焊接熔深2.4~3.3 mm。采用该规范焊接的表面张力贮箱通过了振动、液压、声发射等试验考核，表面张力贮箱满足设计要求，并通过了地面热试车考核。
- Abstract:
- The electron beam welding process specifications were obtained by studying the relationship of surface tension tank assembly precision, weld penetration and morphology. The specifications are: with the virtual focus electron beam welding process, when the virtual focus beam is upper than 30 mA, the seam width of lock bottom portion is 0.7 mm; when the welding beam is 23 mA, welding speed is 1200 mm/min and the weld penetration was 2.4~3.3 mm. The surface tension tank made according to the electron beam welding process specifications passed the assessment of vibration, hydraulic and acoustic emission tests, met the design requirements, and also passed the ground hot fire test.
