Abstract: The present disclosure relates to a welding composition for joining high manganese steel base metals and methods of applying the same. The composition includes: 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 an amount 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 including iron. In an embodiment, the composition has an austenitic phase.
