The electron beam focal post-weld heat treatment (EBLPWHT) is a rather new method that provides the advantages ofhigh precision, flexibility and efficiency, energy saving and higher productivity. This paper studies the effect of two post-weldheat treatment processes on the microstructure,mechanical properties and fracture toughness of an electron beam weldedjoints in 30CrMnSiNi2A steel. EBLPWHT, in a vacuum chamber, immediately after welding and a traditional furnace wholepost-weld heat treatment (FWPWHT) were compared. The experimental results show that, after EBLPWHT treatment, the
