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 …

Why it's free to use
- Filed August 22, 1991 and granted March 26, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 22, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 22, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
