Step 4:After passed examination, counter plate and floor carry out spot welding, and spot welding point is uniform, it is ensured that the stabilization of fit-up gap;
Step 5:The workpiece assembled is fixed on welding turntable and centering, is put into vacuum chamber and vacuumizes so that vacuum Reach 5 × 10-3The welding of workpiece is carried out during below MPa;
Step 6:Take out after vacuum, started electron-beam welder, adjusted the soldering angle of electron gun so that electron gun vertical weld Direction is set, and welds circular weld, and accelerating potential is 55~150KV, and speed of welding is 200~1000mm/min, electronic beam current For 50~350mA, focus current is 1500~3000mA, and electron beam is 0~5.4 in the scanning amplitude of oscillation of X-direction, and electron beam is in Y The scanning amplitude of oscillation in direction is 0~6.0, and welding distance is 200~1500mm;
Step 7:Complete after all welding, by design requirement inspection panel and floor internal diameter and outside dimension, and panel and rib The perpendicularity of plate;
Step 8:Row heat treatment is put into the ring inner sleeve after passed examination, heat treatment temperature is 550~950 DEG C, and soaking time is 0.5~2 hour, tapping temperature≤100 DEG C.
Welding manner in the step 4 carries out spot welding using manual argon arc welding.
Sweep waveform in the step 6 is circle.
Beneficial effects of the present invention:
Suit electron beam welding manufacture method in the T-shaped ring of major diameter that the present invention is provided, can replace the consumable electrode used at present It is set with the T-shaped ring of major diameter prepared by the traditional welding method such as argon arc welding or argon tungsten-arc welding;By being processed and rib on panel Boss of the plate with width, it is ensured that the fit-up gap between panel and floor, using electron beam welding, efficiently solves prior art In in big thickness ring suit T profile welding angle welding is carried out using traditional welding methods such as metal argon arc welding or argon tungsten-arc weldings During welding, the welding efficiency existed is low, and welding deformation is big, and postwelding dimensional accuracy is difficult to accurate guarantee, and angle welding stress collection Middle situation is more serious, easily causes the problems such as structural instability is destroyed;
Replace that low production efficiency, welding deformation be big using electron beam, welding quality be difficult to ensure card, welding material expenditure greatly, work bar The manual welding of part difference has great superiority;The electron beam welding of suit in the T-shaped ring of big thickness can be realized;Significantly improve weldering Quality is connect, probability is reprocessed in reduction;Efficiency is improved, shortens the manufacturing cycle;Ensure suit size tolerance requirements in T-shaped ring;Reduce into This;And big and other shapes the T junction of poor other materials weldability, welding procedure complexity, workload can be promoted the use of In the welding of structure.
