In this paper, the rare earth wear resistant steel NM450F of Baotou Steel is selected to carry out the experimental study of welding and Lincoln low alloy steel welding wire is selected to weld. The welding surface is smooth, surface quality inspection could 100% meet the ISO standard and flaw detection quality of magnetic powder is grade I. The internal flaw detection quality of weld seam could reach grade I as well as there are not such phenomena as incomplete penetration and fusion, which indicates that the surface quality and internal quality of welding are both excellent. The tensile strength of welded joints is greater than 780 MPa, average impact energy at -60 ℃ is greater than 95 J in weld zone and greater than 160 J in heat affected zone, which indicate that the mechanical properties of weld seam for NM450F steel plate could meet the operating requirements of carriage at low temperature working conditions of -60 ℃. The test results of heat input quantity, preheating temperature, welding parameters of interlayer temperature, mechanical properties and hardness values showed that NM450F material could be with good welding quality and welding technological properties under the condition of conventional welding parameters.

In this paper, the rare earth wear resistant steel NM450F of Baotou Steel is selected to carry out the experimental study of welding and Lincoln low alloy steel welding wire is selected to weld. The welding surface is smooth, surface quality inspection could 100% meet the ISO standard and flaw detection quality of magnetic powder is grade I. The internal flaw detection quality of weld seam could reach grade I as well as there are not such phenomena as incomplete penetration and fusion, which indicates that the surface quality and internal quality of welding are both excellent. The tensile strength of welded joints is greater than 780 MPa, average impact energy at -60 ℃ is greater than 95 J in weld zone and greater than 160 J in heat affected zone, which indicate that the mechanical properties of weld seam for NM450F steel plate could meet the operating requirements of carriage at low temperature working conditions of -60 ℃. The test results of heat input quantity, preheating temperature, welding parameters of interlayer temperature, mechanical properties and hardness values showed that NM450F material could be with good welding quality and welding technological properties under the condition of conventional welding parameters.
