Abstract

"APARELHO E MéTODO PARA REVESTIMENTO A LASER". O sistema de revestimento a laser (102) é usado para acumular a formação de material sobre um substrato aquecendo um ponto localizado sobre um substrato formando um poço de fusão sobre o qual o material é alimentado para criar um depósito tendo uma dimensão física. Um meio de detecção óptico acoplado a um sensor optoelétrico que recebe luz através de uma máscara com aberturas é usado para monitorar uma dimensão física do depósito, e um controlador de sinal de retorno (104) ajusta o laser de acordo com um sinal elétrico, daí controlando a taxa de deposição de material. Na configuração preferida, a dimensão física é a altura do depósito, e o sistema adicionalmente inclui uma interface (106) com um sistema de projeto computadorizado incluindo a descrição do componente a ser fabricado, capacitando ao controlador de sinal de retorno (104) comparar a dimensão física do depósito com a descrição e ajustar a energia do sinal de retorno (110). O controlador de sinal de retorno (104) inclui um conjunto de circuitos para ajustar o laser (110).
