The present work seeks a major understanding of weld’s morphology variating welding speed and torch angle. With the goal of determining the higher width, higher reinforcement and lower penetration. For this experiment, it has been used specimen ABNT 1020 with dimensions of 40x6.35x210mm, which will be the objects of study. As addition metal, due to the specimen material, is 410NiMo 1,2mm diameter. Others conditions imposed consists in, standard current 200A – DCEP direct current electrode positive), as gas is argon + 2% oxygen, flow of 12l/min, wire’s source speed is 8.0 m/min, distance of contact is 35mm. It was used a Dino Lite microscope to obtain results, with 50x range. There are graphics and tables to help a better understating and interpretation of the results. The best width specimen was with 300 mm/min of welding speed and torch angle of -10 degrees, with values of 8,434 mm of width. The best reinforcement specimen was with 300 mm/min of welding speed and torch angle of +10 degrees, with value of 4,293 mm of reinforcement. The best penetration specimen was with 400 mm/min of welding speed and torch angle of +10 degrees, with value of 2,033 mm of penetration.
