What is the maximum temperature that can be exceeded in arc welding in degrees Celsius?

In arc welding, the temperatures generated can be extremely high due to the nature of the process, where an electric arc is formed between the welding electrode and the base material. This arc creates localized heating that can exceed substantial temperatures.

The correct answer indicates that the maximum temperature that can be achieved in arc welding is around 30,000 degrees Celsius. This temperature is an approximate figure based on the capabilities of various arc welding techniques, such as gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW). The intense heat produced during these processes allows for effective melting and fusion of metals.

While the other options suggest higher temperatures, they are beyond the practical and observable limits typically reached in welding operations. Understanding the maximum temperature is crucial for evaluating the materials being welded and ensuring that they can withstand such heat without degrading or warping. This knowledge is essential for safe and effective welding practices.
