Droplet temperature measurement in GMAW
IOP Conference Series: Materials Science and Engineering, 2023 Abstract This work presents measurements of the droplet temperature for the Gas Metal Arc Welding process. Four different aluminium electrodes were used for experiments performed under the same conditions. The approach used yielded higher droplet temperatures than were obtained in previous experiments with the same raw data because the ...
