Sažetak

This paper presents the influence of the metal transfer mode during GMAW of 10 mm thick HSLA steel grade X80 on the inclusion and acicular ferrite content in the weld metal. Welding of butt joint specimens was carried out by conventional short circuit and CBT metal transfer mode with different shielding gases and wire feed speeds. Analysis of obtained results showed that the metal transfer mode affects the weld metal structure by influencing the acicular ferrite content in relation to the number and size of the inclusions found in the weld metal.
