PULVERIZER JAW BUILD-UP INSTRUCTIONS
PULVERIZER 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.
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.
After build-up is complete, grind material to be flush with
the flat surfaces of the tool.
Single passes approximately 1” apart. Cover exposed
faces with crosshatch pattern with stringer beads at 45˚
angles to form 1” squares.
Hard-surfacing patterns are indicated by red lines in the
drawings.
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.
