Laser cladding technology, also known as laser additive manufacturing technology, uses high-energy laser as the heat source and metal alloy powder as the cladding material. Through the synchronous action of laser and alloy powder on the metal surface, it quickly melts to form a molten pool, and rapidly solidifies to form a dense, uniform, and controllable thickness metallurgical bonding layer, the...
