710P (AWS
E7010-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 X46, X52, and X56 grade pipe, it may also be
used for welding
root passes in higher grade pipe in some circumstances. Typical
mechanical properties are: Yield
Strength - 69,800 psi Tensile
Strength - 81,200 psi Elongation
(2" Gauge) - 22% Charpy
V-Notch Impact Resistance - 29
ft-lbs @ -20°F 26
ft-lbs @ -50°F The
typical chemical composition of the weld metal is: Carbon
0.10% Sulfur
0.016% Manganese
0.31% Nickel
0.53% Silicon
0.18% Molybdenum
0.24% Phosphorus
0.008% DEPOSITION
