研制的新型电阻焊电源，以80C196KC单片微机为控制核心，以工作于线性状态的MOSFET管组为电流调节器件，首次实现了电阻焊通电瞬间电流波形的任意控制，使采用最佳电流波形点焊成为可能。该电源和于桥带的焊接，成功地解决了传统焊接方法存在的问题，满足了桥带焊接质量的严格要求，实践表明，该电源是用于桥带焊接的理想电源，为同种及异种微型金属件的精密焊接提供了新的方法。

A new tape resistance welding power source based on 80C196KC single-chip microcomputer was developed.The MOSFET group worked at linear state was used as current adjuster.Arbitrary control of current waveform was achieved first in the moment of resistance welding.So that it is possible to weld with optimal current waveform in resistance welding.The power source was used in the welding of bridge band,that solved the problem occurred at traditional welding means,and met the strict requirement of the welding quality of bridge band.The practice shows that it is an ideal power source in the precise welding of minisize metallic workpiece.
