Does GTAW produce more visible light rays than FCAW welding?

GTAW (Gas Tungsten Arc Welding) does indeed produce more visible light rays than FCAW (Flux-Cored Arc Welding) primarily due to the nature of the processes and the arc characteristics involved. In GTAW, the tungsten electrode creates a precise and concentrated arc, which results in a bright light and a higher degree of ultraviolet and visible radiation emitted. This is especially significant during the welding process when the arc is maintained and the heat is concentrated in a smaller area.

In contrast, FCAW uses a consumable electrode that generates a different arc profile and typically releases less visible light due to its broader distribution of heat and the presence of flux that can obscure some of the light. While there are various factors that could influence the visibility of the light produced in both processes, such as welding parameters and environmental conditions, the inherent design of GTAW enables it to produce a more intense visible light output compared to FCAW in standard conditions. As a result, the statement affirming that GTAW produces more visible light rays is accurate.
