Description:

DuraMax E7010 is an all-position cellulosic electrode that is especially 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.

Typical Application & Usage:
  • Light slag for minimal arc interference
  • Deep penetration
  • Clean, visible weld puddle
  • Superior puddle control
  • Recommended for welding API grades X46, X52 and X56 pipe.
  • Cross Country pipe lines.
  • In-plant pipes.
