Abstract (en)

[origin: DE10103045A1] The method involves joining the electrode (1) to a precious metal (2) locally by using heat input generated by a continuously operating laser beam (3). This causes melting at least in the boundary region between the precious metal and the electrode. The precious metal can be completely melted by the heat. Independent claims are also included for the following: an electrode for an ignition plug.
