Abstract
Methods of welding high manganese steel, the methods comprising: supplying at least one piece of high manganese steel; supplying the metal cored wire comprising a steel sheath with a core comprising powders of certain metal and carbon percentages and at least one of: i: sulfur in an amount less than 0.3 wt. %; or ii. phosphorous in an amount less than 0.03 wt. %; or a combination thereof; and the balance with iron; submerging the at least one piece of high manganese steel in a slag and arc stabilizer; and applying a current to the metal cored wire to produce a liquid alloy steel composition on the at least one piece of high manganese steel.
