摘要
根据超声电弧焊的特点,使用有限元分析软件ANSYS,利用改进的三维椎体热模对厚度为4.4 mm的CLAM钢焊接过程进行模拟,寻找在超声电弧焊的最优频率,观察焊缝的微观组织。结果表明,超声电弧焊的最优频率为24 007 Hz,焊缝处组织可以得到较好的细化晶粒,碳化物的生长被抑制,力学性能得到改善。
The microstructure of CLAM steel welding line after ultrasonic arc welding was studied, and the CLAM steel welding process were simulated and analyzed by ANSYS. The results show that the optimal driving frequency of the ultrasonic arc welding is 24 007 Hz. The growth of carbide are stopped due to refining grain, and the mechanical properties of the welding line are improved.
