The research focused on optimizing tack welding parameters for SS304 and S355 thin steel sheets using the MasterTIG 235 AC/DC Welding machine. Tack welding, a crucial initial step in welding, involves creating temporary welds to secure metal components before the final weld. The study aimed to comprehend the impact of welding parameters like current, duration, pulse settings, and material thickness on weld quality. Employing a systematic approach, the research varied parameters for different material thicknesses, conducting visual inspections using Kemppi's MasterTIG 235 AC/DC machine. Results unveiled optimal values for current and duration, offering insights into achieving a balance between penetration, bead formation, and overall weld quality.
The experimental design included meticulous steps, encompassing the setup and calibration of the MasterTIG welding machine, and preparation of SS304 and S355 metal sheets. Tack welding on butt joints of varying thicknesses was performed by systematically adjusting parameters. Weld quality was assessed via visual inspections and machine readings, emphasizing surface level characteristics. Acknowledging limitations, such as exclusive reliance on visual testing, the study suggested future research incorporate a combination of non-destructive testing methods for a more comprehensive examination of both surface and internal aspects.
In conclusion, the experiment provided valuable insights into optimizing tack welding parameters for thin steel using the MasterTIG 235 AC/DC machine. These results high-light the importance of tailored parameters for different types and thin metal of steel and provide practical guidance for welding professionals. Despite recognizing the limitations of relying solely on visual inspection, the study recommends a broader range of non-destructive testing methods to be included in future research. These findings contribute to ongoing efforts in establishing industry standards and welding guidelines.
