摘　　要：通过对比试验研究了直流、交流方波波形参数(频率、平衡和电压偏移)对埋弧焊焊接效率的影响。结果表明,熔深随着频率的增大而减小,随着平衡和电压偏移的增大而增大;熔敷效率随着平衡和电压偏移的增大而减小。进一步试验证明:直流、交流并用有利于提高焊接生产效率。该研究成果为实际工业应用中埋弧焊成形质量提供了理论依据。The effects of DC and AC square wave waveform parameters(frequency,balance and offset)on the efficiency of submerged arc welding are studied through comparative experiments.Results show that the penetration depth decreases with the increase of frequency,and increases with the increase of balance and offset;the deposition efficiency decreases with the increase of balance and offset.Further tests have proved that the combined use of DC and AC is beneficial to improve welding production efficiency.The research results provide a theoretical basis for the forming quality of submerged arc welding in practical industrial applications.
