What if temprature of welding melting temprature ? The temperature at which welding occurs depends on the materials being welded and the type of welding process being used. The melting temperature refers to the temperature at which a material transitions from solid to liquid. For most metals: Steel melts at around 1370–1530°C (2500–2800°F). Aluminum melts at about 660°C (1220°F). Copper melts at around 1085°C (1985°F). Welding is typically performed at temperatures above the melting point of the base metal to allow for fusion, but the welding temperature can be much higher due to the added heat from the welding process (e.g., arc welding, gas welding). For example, in arc welding, the temperature can reach 3000–6000°C (5432–10700°F) at the arc, which is much higher than the melting point of the materials being welded.
