How is the iridium tip of the IRIDIUM POWER welded to the electrode?
We use all-round laser welding to ensure a highly reliable joining.
The 0.4 mm iridium tip that generates the high performance of the IRIDIUM POWER 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 IRIDIUM POWER 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.
