基于逆变脉冲MIG焊脉冲参数的研究

Study on pulse parameters of invert pulse MIG welding

论述了脉冲参数对焊接过程的影响,并阐述在一脉一滴的过渡形式下脉冲参数之间的关系。针对以往的脉冲MIG焊脉冲参数由硬件产生,导致控制系统灵活性和可靠性差、控制精度低,本文利用计算机软件编制脉冲MIG焊波形控制程序,该程序可以根据不同焊接工艺参数输出不同的脉冲控制参数,实现了控制系统的灵活性,满足数字化脉冲MIG焊控制策略。

The impact of pulse parameters on welding process was discussed and the relationship between pulse parameters in the transitional form of one drop per pulse was explained in the paper.For the past pulsed MIG welding parameters were generated by hardware resulting in poor control system flexibility,low control accuracy and reliability.The paper adopted computer software to program control procedure for pulsed MIG welding waveform.This program could output different pulse control parameters according to different welding process parameters to achieve the flexibility of the control system.It could meet control strategy for digital pulsed MIG welding.
