Plastic lamp welding
Advanced lighting solutions for autonomous driving are evolving. Plastic transmission welding using a laser achieves excellent joint tightness without affecting the electronics mounted inside the lamp. The K2 laser system's simultaneous irradiation method is the most advanced type of laser transmission welding method. All seam lines are processed at once without changing the position of the beam to block movement and porosity.

Features
3D surface
It perfectly joins not only straight joints but also 3D shapes on curved surfaces.
Upper step processing
The waveguide jig, which can set a 360° survey direction, performs processing that avoids errors.
Uniform energy distribution
It is in perfect contact with the lamp and emits the laser evenly according to the position of the junction line. Thanks to this, there is no warping due to heat imbalance.

High energy efficiency
Since the laser is irradiated at the closest position to the rib line, unnecessary loss of energy can be reduced

High durability and watertightness
Joint lines with higher rigidity than the material are finely formed without breaking so that strong water tightness is maintained even when external changes occur during operation.

Increased productivity
Compared to conventional laser transmission methods, production speed is increased, and stress at the joint is minimized by local processing.
