Abstract

"DISPOSITIVO E PROCESSO DE CONTROLE DE UMA OPERAçãO DE SOLDAGEM, DE RECARREGAMENTO OU DE USINAGEM POR FEIXE DE LASER DE UMA PEçA". A presente invenção refere-se a um dispositivo de controle da qualidade de uma operação de soldagem, de recarregamento ou de usinagem de uma peça por feixe de laser, compreendendo pelo menos um bocal de sopro de um gás (1) munido de um canal de ejeção (5) de um fluxo desse gás, e munido de pelo menos um captador fotossensível (3) disposto atrás desse canal de ejeção (5), de forma a poder coletar pelo menos um sinal luminoso que penetre nesse canal de ejeção (5), e emitido durante essa operação de soldagem, de recarregamento ou de usinagem, assim como um processo de controle de uma operação de soldagem, de recarregamento ou de usinagem a LASER de uma peça.
