SW15-IP
(AWS E7014)
- This electrode has iron powder added to
the coating, permiting use of higher
welding currents. The deposition rate is increased by the
use of higher welding currents while
the iron powder content of the covering increases the deposition
efficiency. Both of these increases make the welding operation more efficient.
The high
currents and high welding speeds can be used without undercut. The slag
removal is easy
and complete. Typical applications include construction equipment, metal
fixtures, auto- motive
parts, barges and farm machinery. Typical
mechanical properties of SW15-IP weld metal are: Yield
Point - 61,000 psi Tensile
Strength - 71,300 psi Elongation
(2" Gauge) - 28% The
typical chemical composition of the weld metal is: Carbon
0.04% Phosphorus
0.015% Manganese
0.31% Sulfur
0.019% Silicon
0.14% DEPOSITION
