Der Long-Focus Water-Cooled Coaxial 4-Stream Laser Cladding Nozzle from Grünstein ist konzipiert für high-efficiency DED/LMD laser cladding on large components where long working distance, high deposition productivity, Und stable coating quality are essential. Compared with conventional coaxial annular Und 3-point designs, this 4-stream coaxial nozzle delivers a larger powder spot und eine longer standoff, making it especially effective for high-speed cladding and large-area surface processing.

Its optimized coaxial powder delivery forms a concentrated, controllable powder focus that can be precisely matched to the laser spot. When paired with high-power, large-spot laser sources, the nozzle helps achieve higher cladding efficiency while maintaining stable melt pool behavior and consistent layer formation. The water-cooling structure supports long-duration operation and contributes to extended service life, reducing downtime and improving production continuity in demanding industrial environments.

Mit einem 30–31 mm working distance und eine 2–4 mm powder spot size, this nozzle is well-suited for large workpiece repair, remanufacturing, and surface strengthening—including wear-resistant overlays, corrosion-resistant coatings, and heavy-duty component restoration where process stability and repeatability matter.
