300M low alloy steel that has excel-lent mechanical properties, widely used for large structural materials in the aviation industry. For example it is widely used to make the aircraft landing gear. Study on electron beam welding of 300M steel, by the use of scan waveform welding methods, get good the front and back appearance and organization performance of welded joints of 300M, which is especially suitable for welding of pipe parts. Electron beam welding procedure will powerful promote application of 300M steel.
