根据熔滴短路时间与其体积以及向焊接熔池过渡时间的相互关系,确定了焊丝金属从与熔池相接触到向熔池过渡的熔滴过渡控制时间特性;指出了该时间特性适用于各种不同焊丝直径的焊接工艺;证实了施加脉冲焊接电流所获得的附加能量可以缩短短路过渡时间。
According to the relationship between the droplet discharge time and its volume and the transition time to the weld pool, the time characteristics of the droplet transfer control of the weld metal from the contact with the weld pool to the weld pool were determined. It is pointed out that the time characteristic is suitable for various Different welding wire diameter welding process; confirmed the application of pulsed welding current obtained by the additional energy can shorten the short-circuit transition time.
