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。 In this paper, the oxidation of the Zr-2 alloy capacitor storage contact seam welding was studied. The 0.5Be-2.5Co-Cu alloy electrode material with high re-softening temperature and good thermal conductivity was selected. Zr-2 alloy was welded in the air by instant super-rapid heating. First of all to solve the ultra-fast heating welding electrode softening deformation. In the case of constant pulse discharge time of the capacitor, as the stored energy increases, the thickness of the oxide film of the welding joint is increased. In the case of constant storage energy, with the shortening of the discharge time, weldment oxide film thinning.
