Electron Beam Welding of High Manganese Steel Structure

Welding of Non Magnetic Steel (Report 3)

Abstract

High power electron beam welding was applied to manufacture heavy plate welded structure made of high manganese steel in production.
The electron beam welding machine was of high vacuum type with maximum output of 110 KW, the types of steel were 14%Mn-2%Cr-2%Ni-0.6%C, 18%Mn-5%Cr-0.5%C and 18%Mn-5%Cr-0.6%C with V and N, and the penetration depth was 40 to 70 mm.
This report described an effect of P and N content on the solidification crack occurrence, characteristic penetration depth and mechanical properties in electron beam welded joints of these high manganese steels and practical welding of heavy plate products.
