Field girth welding technology for high manganese steel slurry pipelines

A system for providing erosion/corrosion resistant high manganese welds, the system comprising:

• a consumable wire electrode producing a weldment comprising carbon in a range of about 0.4 wt % to about 0.8 wt %, manganese in a range of about 18 wt % to about 24 wt %, chromium in an amount of about ≦6 wt %, molybdenum in an amount of about ≦4 wt %, nickel in an amount of about ≦5 wt %, silicon in a range of about 0.4 wt % to about 1.0 wt %, sulfur in an amount of about ≦200 ppm, phosphorus in an amount of about ≦200 ppm, and a balance comprising iron;
• and
• a gas metal arc welding power source that perform gas metal are welding, wherein the gas metal arc welding power source produces a welding heat input no more than about 2.5 kJ/mm.

A method of producing a weld deposit of erosion/corrosion resistant high Mn steel, the method comprising:

• providing at least two high Mn steel bases to be welded, and a weldment comprising carbon in a range of about 0.4 wt % to about 0.8 wt %, manganese in a range of about 18 wt % to about 24 wt %, chromium in an amount of about ≦6 wt %, molybdenum in an amount of about ≦4 wt %, nickel in an amount of about ≦5 wt %, silicon in a range of about 0.4 wt % to about 1.0 wt %, sulfur in an amount of about ≦200 ppm, phosphorus in an amount of about ≦200 ppm, and a balance comprising iron;
• and
• melting and cooling the welding filler material to create a weld deposit.
