E7010-A1

AWS A5.1 E7010-A1
ASME SFA 5.1 E7010-A1

E7010-A1 is a high cellulose electrode developed specifically for welding pipe lines. Although this electrode may be used in any position, it is best suited for vertical up or vertical down welding. E7010-A1 yields a forceful arc with deep penetration, producing a weld puddle that wets and spreads well, with rapid solidification. Weld deposits are of X-ray quality, with 70,000 psi tensile strengths and containing 1/2% Mo, E7010-A1 electrodes may be used with AC or DC (reverse polarity).

Preheating:

When welding carbon-molybdenum steels, preheating at 300-575oF is recommended. Exact preheat temperature will depend upon the
thickness and hardening characteristics of the work piece.

Applications:

E7010-A1 is most commonly used for welding carbon-moly piping used in high pressure, high temperature steam service and structural shapes,
plates and castings, which have a 1/2% Mo content.
