The applicant observes and finds that the splash of pulse welding is mainly caused by short circuit opening, once a short circuit occurs, abnormal voltage is inevitably generated after each short circuit, the abnormal voltage acts between a droplet and a molten pool, when the abnormal voltage is large, an electric arc is generated in a similar way in an instant, the electric arc inevitably generates electric arc force, the electric arc force acts between the droplet and the molten pool, repulsive force is generated in transition of the droplet, drop of the droplet is influenced, if the droplet after the abnormal voltage does not drop due to electric arc reaction force, the droplet can be continued to a next pulse or drop of the next pulse, at the moment, the droplet in the molten state generated by energy of two pulses is inevitably large, the probability of short circuit occurrence is increased, and the large short circuit can cause larger splash.
Because the occurrence of short circuit can not be completely avoided in the welding process, and abnormal voltage, high or low, duration or long or short time can be generated after short circuit every time, the key for solving the problem is how to reduce the malignant influence caused after the short circuit occurs.

and step S400, if so, compensating the peak current and the peak time of the next pulse according to the difference value between the abnormal voltage and the judgment voltage and the duration time of the abnormal voltage.
According to the pulse welding method, the judgment voltage value of the abnormal voltage is introduced, if the abnormal voltage is higher than the judgment voltage value, the peak current and the peak time of the next pulse are compensated according to the difference value of the abnormal voltage and the judgment voltage and the duration time of the abnormal voltage, so that the peak current and the peak time of the next pulse are increased, molten drop falling is promoted, the occurrence of multi-pulse one-drop transition is reduced, the condition of large-drop transition is reduced, the generation of splashing caused by large short circuit is avoided, and the molten drop transition process and the welding effect with better consistency are ensured.
