Identificação da transferência metálica na soldagem MIG/MAG pulsada de aço inoxidável a partir de um sensor óptico

Abstract

This work is aimed to verify the possibility of the use of an identification metal transfer device, with low costs and high flexibility, in pulsed GMAW. The automated welding pulsed was conducted in stainless steel, using an electronic power source. The metal transfer was recorded by high-speed camera to validate the device efficiency. The voltage and current welding signals, as well as, the optical sensor and camera signal were synchronized to guarantee suitable analysis. The results showed that the device is suitable to be used for metal transfer identification, in pulsed GMAW, with good performance in stainless steel. Thus, it is possible to assert that the developed device is a low cost and high flexibility tool, which can be applied in optimisation of pulsed GMAW.
