Generally, the laser micro-cladding is obtained by materials depositing under interest substrates. The technique consists of coat-powder directing into laser beam's focal region; under a substrate surface; promoting metallurgical bonding between the materials. The system therefore has a wide range of applications in engineering. However, it is still little covered in the literature; especially regarding its boundary conditions. With this in mind, this paper aimed the application and analysis of micro-cladding parameters; from previous studies. To this end, was taken a methodological-route composed by: irradiation starting-parameters. Next, with a deposition of: one-track lines; coat-areas and micro-additive metallurgical manufacturing structures. Using a H13 tool steel as coat-powder, under discoidal substrates 25X5mm of AISI 4340. With an experimental set-up consisted by an Ytterbium fibre laser, transported by a robotic arm and a powder aspersing system. With this, were obtained optimum parameters of laser's power of 1300W and velocity of scanning of 11mm/s. The final results produced structures with well-densification and superior Vickers microhardness; with metallurgical bonding occurrence.
