Descrição: Gas-metal arc welding (GMAW) has received much attention over the last several years and has numerous wide and beneficial applications in different industries. The heat-affected zone (HAZ) is the region between the base and weld metal characterized by the lowest toughness in a welding joint. Hence, this zone is always a matter of interest for many researchers. Our study is focused on the effects of GMAW parameters, including the electrode-to-work angle (φ), filler metal diameter ( d ), and shielding gas type (SGT) on the average HAZ width (AHW) in HQ130 steel. With this aim, different welding samples were produced by employing electrode-to-work angles of 65°, 75° and 85°; filler metal diameters of 0.8 mm, 1 mm, and 1.2 mm, and argon, helium, and carbon dioxide as shielding gases. After termination of the welding process, the average HAZ width was experimentally measured and discussed for all samples. The results of this study indicate that the variations of robotic GMAW parameters have significant effects upon the average HAZ width.
