- Abstract
The paper presents some investigations about the characteristics of composite layers deposited by laser beam remelting on a copper sample. The solution proposed is the development of new electrodes for spot welding reinforced using laser beam remelting and carbides embedding, that are not toxic for people or for the environment, since they do not contain metallic elements such as Cr, Be, Zr. The additional powder material, consisting of WC, was embedded into the copper sample surface, using different parameters values for the Nd:YAG laser remelting process. The structural characteristics and geometric thickness of the melted zone were measured in order to establish a correlation between the penetration and the tungsten carbide distribution for different values of the welding parameters.
