Annealing the Weld
1. When a saw band is butt welded, the site of the weld
“air hardens” and will become brittle. To return the
metal to its approximate original state it must be
gradually heated and cooled several times called
annealing.
2. Turn
the weld force selector knob to “0” as shown in
(fig. 23).
3. Clamp the saw band in the jaws making sure to
carefully center the weld. It is still brittle.
4. Press the yellow annealing button quickly with a few
short bursts to make the weld area a dull orangish-
red. (The wider the blade, the more bursts and time it
will take.) After reaching a dull orangish-red, allow
the area to cool 15-30 seconds and then repeat the
heat twice more.
Too much heat can damage the
temper or burn through and destroy the weld.
5. After welding and tempering the blade, test the strength and
flexibility
of the saw band by bending it in an arc similar to the pulley on the saw.
CAUTION:
The bandsaw blade is sharp and can cut your hand or fingers.
Heat from the welding and annealing process can cause severe burns. Always wear
leather gloves when working near the blade.
