摘要：

Equipment that allows images recording are important tools in study of welding processes. However, high-speed cameras that allow capture of arc images and phenomena involved, such as metal transfer, are limited due to their high cost. Considering use of low cost cameras, the present study has the objective of evaluating the effects of exposure parameters on the arc recording, which is similar to that observed through the welding mask. Therefore, the effects of diaphragm aperture, shutter speed and ISO sensitivity were analyzed. In addition to these parameters, filters were used on the camera lens in order to improve the quality of the images. Finally, the knowledge acquired in the TIG process registration with cold wire feed was applied, being possible to visualize the droplets being transferred as well as the weld pool.
