Electric welding core wire of high manganese steel wire made by forging rolling process

Abstract

A forged and rolled the high-Mn core wire of electrode for electric welding contains C (1-1.3 mass %), Si (0.3-0.5 mass%), Mn (11-14 mass %), P (0-0.035 mass%), S (0-0.25 mass%) and Fe (rest). its advantages are uniform welding, and high quality and strength of welded seam.

Description

1. Technical field

[0001] The invention relates to a welding rod core for welding, in particular to an electric welding core made of forged and rolled high manganese steel wire. 2. Background technology

[0002] The welding performance of high manganese steel is not good, but its high strength, high toughness, high wear resistance and non-magnetic excellent performance make it used in many occasions. However, because high manganese steel hardens quickly and is difficult to cut, it is generally limited to castings. Although it has been used in welding at present, the application effect is not ideal due to the unreasonable composition of the material. The materials currently used for high manganese steel welding are as follows:
