“…Welding parameters must be optimized in order to obtain a good weld joint with the required bead geometry and weld quality [20]. There are also several publications about optimizations of the FCAW process by weld bead geometry analysis [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. In these studies especially the effects of FCAW welding current, welding speed, arc voltage, electrod angle and nozzle to plate distance were investigated.…”

Flux cored arc welding(FCAW) process is characterized with its high deposition rate and productivity. Control of the operating parameters in FCAW is essential to obtain high production rates and good quality welds. Bead on plate welds were carried out on mild steel plates to study the influence of welding current and arc voltage on weld bead geometry parameters. The weld bead coss-sections were metallographically investigated. The effects of these welding parameters were evaluated by measuring penetration depth, reinforcement height, bead width, wetting angle, electrod deposit area and plate fusion area. The bead crosssection area and the weld shape factor were calculated from the measured results. The effects of welding parameters on weld bead geometry have been presented by histograms.
