Ferrite in Standard AWS Pads Vs. Production Welds
For a given metal composition and welding process the magnetic response of a standard weld pad prepared as illustrated in Figure 29 may be somewhat different from the response of individual beads or layers in a production weld. Why? Because of dilution with parent metal, welding practice (arc length, atmospheric contamination and welding current) and varying cooling rates.
