Ferrous metals laser cladding

electric power industry

Product summary
This laser cladding system deposits alloy strengthening layers on components regardless of workpiece size. It combines a continuous laser with a synchronised high-frequency pulsed laser to improve molten-pool dynamics, reduce thermal gradients and enable integration with automated transfer vehicles for industrial production.

Process description

• The alloy strengthening layer is formed by laser melting using a continuous laser as the main heat source while a high-frequency pulsed laser is synchronously applied to assist melting;
• The process is composite: the continuous laser and the high-frequency pulsed laser are oriented at a specific angle α and their spots overlap to form a single molten pool, with the pulsed laser acting directly inside the pool;
• The high-frequency pulsed laser provides local temperature compensation and generates high-frequency shock waves and ultrasonic cavitation combined with impact stirring, increasing molten-pool mobility and reducing temperature gradients to produce an ultrafine equiaxed reinforced microstructure;
• Equipment advantages include no limitation by workpiece size, large action depth, a controllable and simple process and suitability for industrial automation.

Applications

• Surface strengthening and wear‑resistant coatings for shafts, molds and large structures;
• Repair and rebuilding of oversized or complex components;
• Integration into automated production lines for heavy industry, energy and manufacturing.
