A self optimizing intelligent control algorithm of current waveform parameters of CO 2 gas shielded arc welding is put forward.

The article makes a theoretic analysis based on current waveforms of several types of locomotives′ no load turn-on tests,combines with the characteristic data of type TM2 locomotive,calculates and simulates the no load turn-on current waveform of the locomotive,and then gets the existing reason for the no load turn-on current.

The electrode life experiment is carried by controlling current wave and the relation between work piece surface spattering rate, electrode life and the amplitude of current pulse before spot welding, the current time before spot welding is investigated.

Spot welding is greatly affected by the current,so the real-time display of current waveform in the welding is very necessary.

By means of analyzing the relationship of inrush current waveform and magnetization curve, a waveform factor based fast algorithm to distinguish inrush current of power transformer from its fault currents is proposed.
