EH14

The high manganese submerged arc wire, chosen with a neutral flux for multipass welds where the deposit has to reach higher strength and better toughness.

What the designation means

Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.

  1. EElectrode, the bare wire carrying current under the flux blanket.
  2. HHigh manganese content, the richest of the three manganese classes of submerged arc wire.
  3. 14The nominal carbon content in hundredths of a percent, so roughly 0.14 percent carbon.

Polarity
DCEP for single wire work, with AC common on trailing arcs in tandem and multi-wire systems
Shielding
None; a granular submerged arc flux shields the arc, and the wire and flux are classified as a combination

Typical uses

  • Multipass groove welds on heavy plate and pressure vessels
  • Higher strength structural welds requiring good notch toughness
  • Weld overlay and buildup on heavy shafts and rolls

How it runs

  • Rich manganese chemistry supports higher strength deposits than the leaner wires
  • Normally paired with a neutral flux so the chemistry stays stable pass after pass
  • Well suited to multipass work where dilution effects even out
  • Deposit toughness still depends on the flux and the heat input used

Storage and handling

Store coils dry and covered, and give the paired flux the heated storage and rebake handling it requires.
