The arc generated in SMAW reaches approximately how many degrees Fahrenheit?

In Shielded Metal Arc Welding (SMAW), the arc generated can reach temperatures of approximately 6,500 degrees Fahrenheit. This intense heat is critical for melting the base metal and the electrode, allowing for proper fusion and creating a solid weld joint. The high temperature of the arc is also essential for effectively overcoming the melting points of various metals, which can vary significantly.

The selected option accurately reflects the operational realities of SMAW, where the arc's heat is paramount in achieving strong welds in various materials. Understanding the temperature range of the welding arc is crucial for welders to ensure they can manage heat input and avoid issues like warping or burn-through in the workpiece.
