EM14KS is a metal cored, carbon steel electrode for submerged arc welding. It is intended for single and multiple pass welding of carbon, and certain low alloy, steels in the flat and horizontal fillet positions. Select EM14KS contains small additions of titanium which improves weld metal toughness and helps to maintain strength after stress relieving. This electrode should be used for submerged arc welding only.
CLASSIFICATION:
EC1 per AWS A5.17, SFA 5.17.
CHARACTERISTICS:
Select EM14KS is designed to produce a weld deposit chemistry equivalent to that produced by solid wire, EM14K electrodes. The cored wire design results in higher deposition rates than solid wire when run at the same current level. Select EM14KS allows for better control of bead penetration than solid wire. The penetration pattern for a cored electrode is broader and slightly shallower, reducing the tendency for burn through on root passes or poorly fit up joints.
APPLICATIONS:
Select EM14KS is ideal for those applications involving the welding of pressure vessels and structural carbon steels such as A36, A285, A515, and A516. It should be used with neutral fluxes and may be substituted anywhere a solid wire, EM14K electrode is used. TYPICAL DEPOSIT CHEMISTRY:
