During the welding process, the temperature range produced by an electric arc typically ranges from?

The temperature range produced by an electric arc during the welding process typically falls between 3000 to 8300 °C. This range is significant because it reflects the intense heat generated by the electric arc, which is necessary to melt the base materials and the filler material, if used, for proper fusion. The high temperatures facilitate the melting and joining of metals, allowing for strong welds and ensuring that the materials can bond effectively.

Understanding this temperature range is crucial for power engineering operators and welders, as it influences the choice of materials, welding techniques, and the protective measures that need to be implemented during the welding process. The other temperature ranges are either too low or exceed what is generally achieved in conventional electric arc welding, reinforcing why this option accurately represents the typical conditions encountered during welding.
