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.

Deposition Rates vs. Frequency

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.
