| 摘 要： | 本文对Zr-2合金电容贮能接触缝焊时的氧化问题进行了研究。选出了再软化温度高、导热性能较好的0.5Be-2.5Co-Cu 合金电极材料。用瞬时超快速加热方法在空气中焊接了Zr-2合金。首先解决了超快速加热焊接时电极软化变形问题。在电容器脉冲放电时间不变的情况下,随着贮存能量的增大,焊接接头氧化膜增厚。在贮存能量不变的情况下,随着放电时间的缩短,焊件氧化膜减薄。

| Abstract: | The oxidation of Zr-2 alloy weldment during the condenser discharge resistance seam welding has been studied.A 0.5Be-2.5Co-Cu alloy is selected as the electrode material,which has high resoftening temperature and high resistance to the deformation of the electrode during welding.The Zr-2 alloy was welded in air with instantaneous super-high heating rate.In the case of keeping condenser discharging time constant,the thickness of oxidation layer on the workpiece increased with the increase of the energy stored in the condensers.The thickness of oxidation layar decreased with the decrease of condenser discharging time when the energy stored in condenser remained constant. |
