Abstract

With the use of laser welding, it is possible to join different steel, withdifferent thicknesses, with or without the action of protective layers. Thequality of laser radiation makes it possible to get certain characteristics thatare impossible to get by other processes, such as high welding speeds, lessmetallurgical effects suffered by the heat-affected zone (ZAC), and thisprocess also does not require filler metal, therefore it is free from possiblecontamination.Combined with traditional welding methods, laser welding producesnarrower weld beads, allowing for better prevention of corrosion andthermal distortions.Although the process already has high industrial knowledge, some randomdefects, such as porosities and inconsistencies, are still found. This workpresents a systematic study to determine the influence of laser weldingparameters and how these parameters influence welding defects. Forthis, the experimental part was carried out in the welding laboratory -LABSOLDA, of the Federal University of Santa Catarina - UFSC, duringthe laser welding processes, a welding speed of 2.4 m/min was reached. Forthis experiment, argon was used as a shielding gas and 1020 steel was usedas the base material.
