Penetration vs. Frequency
Figure 9 compares three .31” (7.9mm) horizontal fillet
welds made at 10, 70 and 90 Hz. All were made at the
same heat input and travel speed. Penetration ranges
from 2.1mm to 3.2mm in depth.
Frequency also plays a role in total deposition rate.
Deposition rates may increase about 6% as the
frequency is lowered. Deposition rate decreases
slightly as frequency is increased. This could be
significant, when producing large single pass
fillet welds.
