Laser Metal Deposition
Laser metal deposition is a process where metal powder or wire is melted with a laser beam and deposited onto the workpiece surface. It is used for repairs, claddings, and building 3D structures.
Physical-Chemical Mechanism of Action
A high-energy laser beam melts metal powder or wire on the material surface. The molten mass is then shaped by the movement of the laser and cooled, solidifying into the desired form.
Metallurgical Relevance & Risks in Welding
This process enables precise repairs and coatings with high resolution. It reduces material waste and can produce more complex structures than traditional welding methods. However, inaccurate laser adjustment can lead to defects such as deformation or lack of fusion.
Workshop Practice & Instructions
Use a high-quality laser device with precise control. Ensure the metal powder or wire is clean and free of contaminants. Hold the laser tip at the desired position and move it slowly into the desired shape. Maintain constant speed and temperature to achieve a homogeneous result.
