Build-Up Recommendations; Hardsurfacing Recommendations - Labounty CP 80 Safety, Operation & Maintenance Manual

BUILD UP
RECOMMENDATIONS
Refer to the list of AWS classifi cations below to
select a suitable build-up material for LaBounty
concrete pulverizers. Weld products within these
classifi cations meet the combined requirements for
strength, toughness, and ductility that are essential
for LaBounty applications.
Shielded Metal Arc Welding - Stick Electrodes
E7018
E8018-C3
Gas Metal Arc Welding - Solid Wire Electrodes
ER70S-6
Gas Metal Arc Welding - Flux Cored Electrodes
E71T-1
E71T-1M
E80T1-Ni1
E80T1-Ni1M
Gas Metal Arc Welding - Metal Powder Cored
Electrodes
E70C-6M
E80C-Ni1
Welding suppliers can assist in identifying products
that meet these AWS classifi cations.
NOTICE
Using improper build-up and hardsurfacing products
may result in premature wear or increased potential
for cracking and may compromise warranty coverage.
NOTICE
Do not use stainless hardsurface rod. It is too brittle
for LaBounty applications and has a tendency to
crack, weakening the base metal.
CONCRETE PULVERIZERS
HARDSURFACING
RECOMMENDATIONS
For hardsurfacing, Stanley LaBounty recommends
Amalloy 814H rod or equivalent. It is important to
always use a hardsurfacing weld material with a
chromium content of less than 10% and a severe
impact-resistance rating to prevent cracking.
If in doubt about what hardsurface material to use,
please contact the Stanley LaBounty Customer
Service Department. Failure to adhere to LaBounty
hardsurfacing recommendations may compromise
the attachment warranty.
Hardsurfacing should be applied directly on top of
the build-up welds. The build-up acts as a bonding or
underlayment for the hardsurfacing. This reduces the
chances that the hardsurfacing will crack.
