What is the best welding temperature for copper pipes?

1. Welding temperature of manual arc welding of copper tube: The preheating temperature of manual arc welding of copper tube is generally around 400~500℃. 2. Welding temperature of copper tube gas welding: gas welding is the high temperature generated by the combustion of welding gas, and the maximum temperature is generally not more than 2000℃, and the temperature in the welding zone only needs to reach the melting point of the welding material. The preheating temperature of copper tube gas welding should not be too high, otherwise the mechanical properties of welded joints will be reduced. 3. Welding temperature of manual argon arc welding of copper tube: the arc temperature of argon arc welding can reach above 10000℃, and it should be six or seven thousand degrees when welding copper.
