Notes:
For laser-GMA hybrid welds, the relationship between the process parameters and bead shapes wasinvestigated by using the experimental design and the non-linear regression. The weld beads werefitted by two quadratic functions. By the statistical analysis, the primary bead was mainly affected byGMA welding parameters and the root bead was mainly by laser welding parameters. The root beadshaped deeper penetration and shallower width, as the laser power increased for the constant arcpower. High laser power resulted in the martensite phase, therefore exhibiting the sudden increase ofhardness as approached to the fusion line of the root bead
