The knowledge of parameters in processes, helps choosing the better method to a specific situation. The present purpose analysis Flux-Cored Arc Welding (FCAW) in carbon steel. The experiment consists in FCAW with 410NiMo of 1.2mm of diameter in plate of ABNT 1020, using argon + 2% oxygen as protection gas. The conditions as, current, torch angle, wire’s source speed and flow of protection gas. Then, two parameters was variated: welding speed and distance of contact, interpreting and comparing the welding’s features. The largest width (8,997 mm) and the largest reinforcement (4,052 mm) were obtained with a welding speed of 300 mm/min and 35 mm contact nosepiece distance. The lowest penetration was obtained with 400 mm/min welding speed and 35 mm distance of contact.
