A method and apparatus for reducing the energy consumption and minimizing the martensite formation when joining a connecting piece of metal with a metal surface by pin brazing, involving exact measurement and control of the energy required for melting down a given lead against a given work piece surface. The current is controlled such that the energy imparted to melt the lead will be interrupted when a precise energy required for melting off a given melting lead is achieved, automatically forwarding the melted lead as the lead is melted off, and interrupting the process after a pre-defined time interval has expired that the length of the welding arc/distance between the melting lead and the work piece remain constant during the brazing process.
