Evenmatched FCAW process in API 5L X80 steel welded joint

The evenmatched welding conditions in FCAW-G process were used in API 5L X80 steel. In this study, two joint geometries (bevel 25° and 35°) with different process parameters were used. Each type of joint was welded with one type of consumable: AWS E81T1-Ni1C (evenmatched), with variation of heat input. During welding the voltage and current varied in a range, in order to preserve the transfer mode by short circuit. For each welded joint, it was studied the influence of these welding parameters in the weld metal's quality and, the influence of the bevel angle in the extent of heat affected zo...
