“…The novel method was proposed to predict arc light noise in order to develop the accuracy of arc vision [13]. Narrow band filters (with 696.5 and 794.8 nm) were usually used for Ar-I monitoring when the welding arc temperature distributions were studied with Fowler-Milne [14][15][16]. The different arc light energy distribution could also reflect the typical charged particles and certain charged status [17].…”

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.

“…From measured spectroscopic data, the plasma temperature can be determined using atomic line intensities, intensity ratios of two or more spectral lines or the ratios of line-to-continuum intensities [11]. Among these methods, the Fowler-Milne method [12][13][14][15] and two-line relative intensity method have been used widely due to their precisions and stabilities. However, only a few studies of GMAW processes by spectroscopic methods were reported [15,16].…”

The transfer modes in gas metal arc welding have important effects on welding quality. However, present study of metal transfer modes is not yet fully understood. In this study, welding arcs was visualised using the optical emission spectroscopy technique. The carbon steel wire electrode was used for welding with 80% Ar + 20% CO 2 shielding gas. The results showed that the globular to spray transition current was 330-350 A. During globular to spray transition, argon,CO 2 and Fe plasma tended to gradually change from localising near the arc axis to a two-layer structure having 11,000 K in high-temperature region away from the arc axis and around 7000 K in lowtemperature region near the arc axis.
