The Long-Focus Water-Cooled Coaxial 4-Stream Laser Cladding Nozzle from Piatra verde este proiectat pentru placare laser DED/LMD de înaltă eficiență on large components where long working distance, high deposition productivity, și stable coating quality are essential. Compared with conventional coaxial annular și 3-point designs, this 4-stream coaxial nozzle delivers a pată de pulbere mai mare și un distanță mai mare, 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.

Cu un 30–31 mm working distance și un 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.
