介绍了采用熔化极脉冲氦弧焊工艺焊接大厚度铝合金燃料箱的优越性。
The priority of using melted pole pul se heliarc welding technique to weld the thick aluminum alloy fuel tank is introduced.
在氩弧下，影响熔池形貌的另一个重要的驱动力是气体剪切力，而氦弧下则是电磁力。
However, the effect of electromagnetic force is stronger than that of the plasma drag force in helium arc.
虽然美国宇航局用它来给航天飞船的燃料箱加压，氦主要还是用来做弧焊和裂纹检测。
Helium is used for arc welding and leak detection, mostly, although NASA USES it to pressurize space shuttle fuel tanks.
