Remember that for a larger fill wire the energy must be
increased to completely melt the wire. If there is insufficient
energy there may only be partial melting of the wire. However,
in some situations this may be advantageous.
HANDS ON: Try adding fill wire using the side placement method. Build up a small mound of
material.
TOP PLACEMENT: With top placement the material addition process will depend a great deal on
the wire size and the weld energy. If the wire is very small, the results will be similar to the side
placement discussed above. For a small wire welded with high weld energy (relative to the wire
size) the weld plasma powers through the wire. is technique melts the base metal and joins the
melted wire to the base plane. However, if the wire is larger or the energy is set to produce only
a small spot size, the wire will typically fail to be added to the base material. Instead the wire will
ball and some melting of the base material will occur, which is insufficient to add the wire.
Placing the weld electrode on top of the fill wire at a 90deg angle from the base material surface
is typically not the preferred method of adding material. If the wire is large compared to the
energy setting, the wire will ball due to surface tension and will not be added to the base material.
