Abstract

This paper presents the development and automation of the innovative laser cladding equipment.<br/>The need of control parameter as overlapping, number of clads, deposition rate, laser power and powder feeder rate are very import in the process and they influence the mechanical proprieties and durability of the coatings. With the automation of the process is possible guarantee the quality of the product. To achieve the objective of this work it is necessary to survey all electrical, electronic and mechanical components of the constituent systems. The laser cladding layout and the process must be very well studied to be developed, the automation and optimization. A program with graphic interface was develop in C# language to allow control simultaneously the main components of the tree systems: laser, powder feeder and system position XYZ. So, with only one program was possible control and define all the parameters of the process and of the equipment. So, was possible<br/>obtain different chemical compositions in one sample keeping the same process control parameters, varying linearly the mass flow rate from two metallic materials in synchronization with the translation movement of XY table.<br/>
