ABSTRACT A transient pulsed arc was studied with narrow band 696.5 nm filters. The arc energy distribution was considered by a ratio: a certain region energy (intensity × region area)/sum. The results indicated a large intensity region appeared with a pulsed arc, which were considered as high-energy regions. They increased while the low-energy regions were compressed. The distribution ratio was changed by the ‘waves rush’ pattern with a large current or pulsed arc. Spurious energy concentration was found at the bottom of the arc. The pulsed arc with 10 kHz at 100 A had optimal characteristics in geometry and energy distribution. The essence of the pulsed arc was considered as constricting energy regions and creating high-energy density. ‘Onion-Kasuga’ algorithm was proposed to reconstruct the arc intensity.

脉冲弧光监测和弧焊温度重建

摘要 使用窄带 696.5 nm 滤波器研究了瞬态脉冲电弧。电弧能量分布按比例考虑：一定区域能量（强度×区域面积）/总和。结果表明，出现了具有脉冲电弧的大强度区域，该区域被认为是高能量区域。它们在低能量区域被压缩的同时增加。分配比率由具有大电流或脉冲电弧的“波浪冲击”模式改变。在电弧底部发现了杂散能量集中。100 A、10 kHz 的脉冲电弧在几何形状和能量分布方面具有最佳特性。脉冲电弧的本质被认为是限制能量区域并产生高能量密度。提出了“洋葱-春日”算法来重建电弧强度。
