SUREWELD
7024 (AWS
E7024) Conforms
to 7024-1
- The Sureweld 7024 electrode
is approved by the American Bureau of Shipping. It is a high speed electrode
using heavy concentrations
of iron powder in the coating. Used with high welding currents, it pro-
duces high deposition rates in horizontal
fillet and flat welding positions. The electrode has
excellent operator appeal and produces
equal leg 45° fillets that eliminate overwelding. The
welds have excellent appearance and
a self-cleaning slag. The 7024 electrode is ideal for
making high speed horizontal fillets
and lap welds on mild steel and some low alloy steels in
weldments such as earth moving and
construction equipment, truck bodies, ships, barges and railcars.
Typical mechanical properties of 7024
weld metal are: Yield
Point - 71,000 psi Tensile
Strength - 81,000 psi Elongation
(2" Gauge) - 26% Reduction
of Area - 63% Charpy
V-Notch Impact Value - 25 ft-lbs @ 0°F The
typical chemical composition of 7024 weld metal is:
Carbon 0.06%
Phosphorus 0.010%
Manganese 0.80%
Sulfur 0.018%
Silicon 0.27%
