一、脉冲控制法的基本原理当稳定的熔透过程受到干扰而发生未焊透时,通过脉冲电流宽度和幅值的同时增加使熔透得以保证,以保证小孔过程和焊缝熔透质量的稳定性,这种方法简称为脉冲控制法。以前讨论的脉宽控制法,对于壁厚为4～5毫米以上的焊件是一种理想的控制 First, the basic principles of pulse control method When the penetration of the stable penetration process occurs when the penetration is not penetration through the pulse current width and amplitude increase while ensuring the penetration to ensure the penetration process and weld penetration quality The stability of this method referred to as pulse control method. The pulse width control method discussed earlier is an ideal control for weldments with wall thicknesses of 4 to 5 mm
