The invention provides pipe line steel for high linear energy welding and a manufacturing method thereof. The pipe line steel for the high linear energy welding comprises the following components in percentage by weight: 0.05 to 0.08 percent of carbon, 0.15 to 0.35 percent of silicon, 1.5 to 1.8 percent of manganese, 0.004 to 0.006 percent of nitrogen, 0.012 to 0.016 percent of titanium, 0.02 to 0.04 percent of aluminum, 0.05 to 0.08 percent of rare earth elements, 0.03 to 0.07 percent of niobium, 0.2 to 0.4 percent of nickel, 0.2 to 0.5 percent of copper, not more than 0.010 percent of phosphorus, not more than 0.005 percent of sulfur, not more than 0.002 percent of oxygen and the balance of Fe and other inevitable impurity elements, wherein the weight ratio of the titanium to the nitrogen is controlled to be between 2 and 4, the weight ratio of the aluminum to the nitrogen is controlled to be between 3 and 10, and the yield strength Rt 0.2 of the pipe line steel for the high linear energy welding is more than 570 MPa. The pipe line steel has a typical needle-like ferritic structure, high comprehensive mechanical properties, high linear energy welding performance and low cost.
