by

The angle between the impinging jet stream centerline and a direction perpendicular to the plate surface.

by

Re-solidified molten metal and oxides adhering to the top or bottom edge during thermal cutting.

The change in chemical composition of a welding filler material caused by the admixture of the base material or previously deposited weld material in the deposited weld bead. It is normally measured by the percentage of base material or previously deposited weld material in the weld bead.
