How is the iridium tip of the
welded to the electrode?
We use
all-round laser welding
to ensure a highly
reliable joining.

A
The 0.4 mm iridium tip that generates the high performance of the
is an alloy with a very high melting point. Therefore,
ordinary resistance welding cannot be used because the iridium does not melt
enough and an adequate weld strength cannot be guaranteed.
“All-round laser welding”, which employs a high-energy laser, is used in the
to melt and weld all around welding points.
Because all area to be welded is completely melted, the welding point is
extremely reliable, thus ensuring stable and quality response without changes in
the electrode, even under heavy driving conditions.
