Abstract: Laser cladding automated processing becomes more and more widespread in manufacturing industry. Meeting an increasingly demanding for cost reduction to purchasing and line or contract activities stoppage. As well, the reduction of worn parts disposal. However, according to literature, these processes aren't systematized. In this way, this paper aimed a production of process chart, determining laser cladding parameters for a better efficiency. Using H13 and WC powders as cladding under structural steel substrates, based on optimal cladding morphology. For this, a 1500W Ytterbium fibre laser was used. With beam diameter of 6 mm, coupled to a Yaskawa Motoman robot arm. The process chart shown a dilution of 39 % with a clad angle of 152° optimum. With parameters of velocity of scanning of 5 mm/s, 85% of laser power efficiency and powder feed rate of 4.4 g/min. Thus, improving micro hardness (MHV) properties than starting materials. Concurrently, the algorithm implemented on the robotic arm, produced a virtual scenario when transferred to software RoboDK. With this it was possible to modify the laser track to suit other application scenarios. Thus, this methodology development was able to optimize automated cladding processes. Besides producing a mirror-virtual interface, contributing to its continuous improvements
