建立了熔化极气体保护焊（GMAW）点火时间的预测模型，得出了计算点火时间的公式，结果表明，点火时间不仅与电热特性有关，还与丝径有关，计算的点火时间与实验点火时间吻合较好，证明了该计算方法的有效性该模型具有较高的准确性和可靠性，可为理解GMAW点火过程和设计合理的电源提供指导和建议。
The prediction model of gas metal arc welding(GMAW) ignition time was established and the(equation) of calculating ignition time was obtained.The result shows that the ignition time has relationship with not only the heat and electric characteristic but also the wire diameter,ignition current and ignition contact voltage.The calculating ignition time is consistent with experiment ignition time and the result proves that this calculating(equation) has rather veracity and reliability.This model can provide the guidance and advice to understand GMAW ignition process and to design reasonable power source.
