Stir Welding With FiberScan™ HR

Laser Mechanisms’ new FiberScan™ HR is a scanning head for high-power laser sources including Fiber, Disk, CO2 and Diode lasers.

Available for collimated beams up to 48 mm diameter, FiberScan™ HR can deliver 20+ kW of laser power to any point within the system’s field of view. FiberScan™ HR employs direct water-cooled copper optics for all wavelengths throughout its optical path to provide reliable, ultra high-power capability with minimum thermal focus shift.

The rugged design is optimized for high power and long processing times required in applications such as continuous welding on roll forming systems, additive manufacturing of sizable structures and large area or volume cladding. In addition, high-speed operation up to 500 Hz in a smaller field enables wide gap seam welding and laser stir “wobble” welding of materials that are difficult to process.

Sensing Non-metals With UltraSense™

Capacitive height sensing for focus following is common in metal cutting systems, but has never been available for non-metal processing – until now.

Laser Mechanisms, utilizing their patented capacitive height sensing unit (HSU) and control interface, has developed UltraSense™, an all-new technology that accurately senses non-metals.

UltraSense™ employs state-of-the-art, height-sensing circuitry specifically configured to detect the surface position of non-metals such as composites, polymers, glass and many other materials for auto-focus laser cutting. Flat sheet cutting systems, as well as 5 or 6-axis machines and robots, can employ this technology. During setup, the HSU is calibrated for the specific polymer being used and only a few materials cannot be sensed with this technology.

UltraSense™ works with Laser Mech’s standard HSU interface systems which allow programmable tip-to-part stand-off distances, as well as their industry-leading auto-calibration feature. Within Laser Mech’s product line, FiberMINI® and FiberCUT® can be equipped with UltraSense™. In addition, retrofits are available for many of Laser Mech’s legacy products already in the field.
