What is the typical arc temperature in GTAW?

In Gas Tungsten Arc Welding (GTAW), the temperature of the arc is a crucial factor that influences the welding process and the quality of the weld. The correct choice reflects the typical maximum arc temperature, which can reach around 11,000°F. This high temperature is necessary for melting the base metals and the filler material, allowing for good fusion and effective penetration.

Achieving such high temperatures helps in producing clean welds with minimal impurities, as the elevated heat can thoroughly melt the materials being joined. The intense heat generated in the arc also allows for a greater control over the weld pool, making GTAW a preferred choice for thin materials and applications that require precision.

The other temperatures listed, while they might seem plausible, do not accurately represent the typical capabilities of the GTAW process when considering optimal arc conditions. Thus, understanding the high-temperature characteristics of GTAW is essential for effective application in various welding scenarios.
