CRACKER JAW BUILD-UP INSTRUCTIONS
CRACKER JAW HARD-SURFACING
PATTERNS
Procedure:
Follow the General Welding Guidelines and Rules.
Determine the area to build up, using a straight-edge or
square. Do not allow jaws to wear to more than a 3/4”
radius on edges of tool. Do not allow blade pocket to wear
lower than the height of a new blade. Use a new blade to
help determine build-up height for the pocket.
Build up the jaw to slightly higher than the original parent
material profile with E7018. Apply single passes in each
line with the grain of the steel, peening after each pass.
See drawings for grain, as indicated by arrows. (Red lines
indicate hard-surfacing pattern.)
After build-up is complete, grind material to be flush with
the flat surfaces of the tool or, if building up a blade seat,
grind material to be flush with a new blade.
Single passes approximately 1” apart. Hard-surfacing
patterns are indicated by red lines in the drawings.
Crosshatch may be used in place of straight stringers on
flat areas of the jaws.
Do not crosshatch the curved
areas of the jaws near the pivot.
Use only straight
stringers on these areas.
Follow hard-surfacing instructions on page
46.
