SW15 (AWS
E6013) -
This is a fine high production electrode that can
weld thicknesses from light gauge sheet to heavy plate. High welding currents
and travel speeds
can be used without undercut. The slag is self-cleaning. SW15 may
be used to weld metal
fixtures, road equipment, farm machinery, building structures, storage tanks,
and iron work.
Typical mechanical properties of the
weld metal are: Yield
Point - 63,000 psi Tensile
Strength - 71,000 psi Elongation
(2" Gauge) - 24% Reduction
of Area - 49% The
typical chemical composition of the weld metal is: Carbon
0.06% Phosphorus
0.012% Manganese
0.32% Sulfur
0.013% Silicon
0.23% DEPOSITION

6013LV
(AWS E6013)
- The arc characteristics, weld metal properties and
in- tended
applications are similar to SW-15 (E6013) electrodes. This electrode
is intended for use
on AC power sources where there is less than 50 open circuit volts. These
lower open circuit
voltage machines make the arc initiation and restrike difficult with a conventional
E6013 electrode.
The 6013LV is a suitable replacement for SW-15.
