Can you overheat copper pipe when soldering?

In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.
Why are copper fittings cleaned before soldering or brazing?
It cleans the metal making the solder stick to the fittings and pipe better it cleas oxides and oils. The longer that copper is kept at the higher brazing temperature, the greater the formation of copper oxide, and nearby valves may be overheated. Why is it important to heat braze joints as quickly as possible?.
