1,048,092. Welding by fusion; making turbine rotors; working at specified temperatures. TERNI SOC. PER L'INDUSTRIA E L'ELETTRICITA. Jan. 31, 1964 [Feb. 1, 1963], No. 4352/64. Headings B3A, B3R and B3V. A steel component of high hardenability is provided with a weldable zone by coating the zone with a layer of weldable metal and hot plastic working the layer. Turbine discs of a steel containing 0-27% C, 3À68% Ni, 1À65% Cr, 0À52% Mo, 0À13% V, 0À05% W, 0À22% Si, 0À58% Mn are pre-heated to 100-400‹ C. and provided at their weld areas with layers of a steel containing 0À05% C, 2À6% Ni, 0À68% Cr, 0À52% Mo, traces of V and W, 0À22% Si, 0À58% Mn by use of an electrode. The discs are heated to 850-1350‹ C. and the layers are forged, hammered, pressed or rolled. The discs are then heat treated by quenching from austenization temperature and tempering at below 700‹ C. After machining the discs are joined by arc welding and are stress relieved at 700‹ C.
