PULSE SPREAD TECHNOLOGY
LASER WELDING INNOVATION
US PATENT #9,067,278
PULSE SPREAD TECHNOLOGY is a novel laser welding innovation that is ideal for joining dissimilar materials. The Pulse Spread Technology method works by rapidly changing laser power relative to laser position, making joining different materials simple.
WHAT IS IT?
- Novel laser welding innovation that is ideal for joining dissimilar materials.
- Method works by rapidly changing laser power relative to laser position.
- High speed mirrors are used to steer the laser beam while power is modulated.
- Fast, real-time control using field programmable gate array (FPGA) control.
WHY IS THIS IMPORTANT?
- Dissimilar materials can be difficult to seam together in a robust way.
- Pulse Spread Technology makes joining different materials simple.
HOW DOES IT WORK?
- The controller sends an analog signal to the laser, controlling the power, while simultaneously sending motion control signals to steering mirrors.
