810P (AWS
E8010-P1)
- An all-position cellulosic electrode espe-
cially suited for welding high strength
pipe. It produces the consistent, deep penetration
required to maintain a proper keyhole
when vertical-down welding in open root pipe joints. X-
ray quality welds can be produced using
flat, horizontal, overhead, vertical-up, and vertical- down
procedures. Recommended for X60, X65, and X70 grade pipe.
Typical mechanical properties are:
Yield Strength - 72,700 psi
Tensile Strength - 88,300 psi
Elongation (2" Gauge) - 24%
Charpy V-Notch Impact Resistance
- 31 ft-lbs
@ -20°F 25
ft-lbs @ -50°F The
typical chemical composition of the weld metal is: Carbon
0.10% Sulfur
0.014% Manganese
0.48% Nickel
0.98% Silicon
0.24% Molybdenum
0.11% Phosphorus
0.008% DEPOSITION
