LOWER SHEAR BUILD UP
AND HARDSURFACING
continued
6. Apply build up to the worn areas in single passes,
side-by side, running with the grain of the base
material (see General Rules for Build Up and Hard-
surfacing). Use the air-operated slag peener to peen
each pass to relieve weld stress and remove slag.
Grind all edges to 90°.
NOTICE
Check temperature regularly during this procedure.
Maintain 400-450°F (200-230°C). Do not exceed
450°F (230°C).
7. If necessary, build up the area beneath the edge
of the secondary blade so it is fl ush with the blade
(see Figure 5-37). The blade should not stick out
beyond the edge of the seat in this area.
8. To hardsurface the top sides of the lower shear,
establish the pattern with three or four passes of
build-up. These beads should run parallel to the
blades from the nose plate back to about the mid-
point of the primary blade. Do this on the guide
blade side also. This will establish the hardsurfacing
pattern and serve as an underlayment.
9. Apply a bead of hardsurface rod on top of each
of the underlayment beads. DO NOT apply hardsur-
face directly to the parent material. It is important
to use an air operated slag peener on each pass of
weld to relieve stress.
