36 Wear-O-Matic
15 No AWS Classification
DCEP or DCEN (Electrode Positive or
Negative) Open
Arc-Hardsurfacing Alloy Severe
Abrasion Resistance Description:
Wear-O-Matic 15 - 7/64" (2.8 mm) diameter
open arc wire is a hardsurfacing alloy with outstanding resistance
to wear caused by severe abrasion. Wear-O-Matic
15 produces extremely high abrasion-resistant qualities that make it an outstanding
surface material
for pug mill knives and augers, dry cement pump screws, conveyor screws, and asphalt
mixer paddles
and shanks. Procedure:
Recommended amperage range, 175-300
amperes at 30-35 arc volts. A weaving bead of 1-1/2" (38 mm) in
width is recommended in order to develop
maximum abrasion-resistant qualities in the deposit. Deposit
thickness should be limited to two
passes or 1/4" (6.4 mm). Typical
Mechanical Properties: The
deposit of Wear-O-Matic 15 open-arc wire attains maximum hardness as deposited
and is unaffected by
heat treatment. In most cases, stress relief check cracks appear in the deposit
but do not impair the abrasion
resistance or the ability of the deposit to take a high polish. Weld deposits
cannot be cut with oxy- acetylene
torch or by air carbon-arc cutting. Continued
