Abstract
This work consists of a literature survey of a laser surface cladding in order to investigate techniques to improve the cladding rate for the process. The high local heat input caused by the high power density of the laser generates stresses and the process is consider as slow when large areas are processed. <p>To avoid these disadvantages the laser cladding process velocity can be increased three or four times by use of preheated wire instead of the powder delivery system. If laser cladding is combined with plasma, TIG, MIG etc the process shows similar results. Another way to avoid the advantages is use of an additional power source, suitable for the laser cla...
