Laser Cladding
An additive welding process for depositing metallic powders or wires via a focused laser beam for repair or surface enhancement. It minimizes distortion and allows a metallurgically pure bond.
In laser cladding, you apply a filler material – powder or wire – onto the component using a laser beam. The beam simultaneously melts the surface of the base material and the filler, creating a true metallurgical bond. Heat input is very localized and easily controlled, which minimizes distortion. But pay attention to correct focusing and feed rate. If the focus isn't right, you won't get a clean bond, and if you go too fast, the powder won't melt properly. Likewise, adjust the powder feed rate to match the beam – too much powder cools the melt pool too much, too little results in a thin, weak layer.
