Statistical analysis of MIG-laser CO2 hybrid welding of Al–Mg alloy

摘要: Abstract Statistical based experimental analysis techniques are particularly useful in the engineering world for improving understanding of manufacturing processes and development new ones. In this paper innovative arc-laser welding process (hybrid welding) is investigated by means a regression model full factorial experiment. Both experiment output were checked variance. particular main effects interactions between parameters on weld penetration 3 mm 5005 Al–Mg alloy bead-on-plate samples calculated plotted. The results showed significance some indicated way to maximize penetration.
