 Print Sheet


CLASSIFICATION: EC1 per AWS A5.17, SFA 5.17.

Select EM13K-S is a metal cored, carbon steel electrode for submerged arc welding only. This electrode contains a higher level of silicon than EM12KS electrodes making it more tolerant of rust and millscale.


APPLICATIONS: Select EM13K-S is ideal for those applications involving the welding of structural carbon steels such as A36, A285 and A516. It may be utilized with neutral or active fluxes and may be substituted anywhere a solid wire, EM13K is used.


DIAMETERS: 5/64", 3/32", 1/8", 5/32"

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Produces a weld deposit chemistry equivalent to that provided by solid wire, EM13K electrodes.
  • Results in higher deposition rates and better control of bead penetration than solid wire.
  • Reduces the tendency for burn through on root passes or poorly fit up joints.
