After the completion of workpiece welding in vacuum chamber (2), opens connection charging vacuum chamber (3) and weld the sealed gate between vacuum chamber (2)
(2.4), transmission welded workpiece enter welding bench (7), be completed welding workpiece be then transmitted to charging vacuum chamber (3) into
Row exchange position, is then shut off sealed gate (2.4), feeds vacuum chamber (3) pressure release, opens feeding seal door (3.7) and sends out
Workpiece is completed in welding, carries out recycling continuous welding with this；
3) when needing to eliminate workpiece welding stress, according to adding for the Attribute tuning electron beam welding device (6) of welding workpiece material
Fast voltage carries out whole heating to welding workpiece between 5~150KV, while cooling dome lifting hydraulic cylinder (7.16) pushes up lower cooling dome
(7.15) to above welding workpiece, gasifier (10.7) starting after 99.99% purity liquid nitrogen gasification into liquid nitrogen central distributor
(7.17) and by electromagnetism spray head (7.19) it is sprayed on progress nitrogen protection heating in welding, heats welding workpiece integrally more
Uniformly；Electron beam welding device (6) stops heating, cooling dome lifting hydraulic cylinder (7.16) top after welding workpiece is heated to set temperature
Lower cooling dome (7.15) covers welding workpiece completely, and gasifier (10.7) is closed, and liquid nitrogen enters liquid nitrogen central distributor (7.17)
And but by electromagnetism spray head (7.19) continuous enterprising promoting the circulation of qi quenching of welding workpiece for being sprayed onto heating, electric rotating while liquid nitrogen sprays
Machine (7.14) drives the welding workpiece rotation on turntable (7.6), makes the cooling more uniform stabilization of air quenching；Welding workpiece is in air quenching
Weldering fume purifier (8.2) starting while cooling extracts the hot gas that air quenching generates out by expansion corrugated pipe (7.18), improves air quenching
Cooling effect；
4) when equipment, which needs to switch argon arc welder (8), to be worked, welding vacuum chamber (2) is beaten with charging vacuum chamber (3)
Pressure release is opened, flexible servo hydraulic cylinder (2.3) shrinkage band piston sealing plate (2.2) is moved to right along lateral guide rod (2.1), is withdrawn into
Weld vacuum chamber (2) outside, electron beam welding device (6) are taken out in disassembly flange I (6.1), and change the method for being connected in original station
The welding gun (8.3) of blue II (8.33), the welding gun connecting leg (8.11) on welding machine (8.1) pass through through-hole (8.12) and connect argon gas interface
(8.32), the liquid nitrogen import II (8.31) being located on welding gun cooler II (8.39) and nitrogen outlet II (8.34) by vacuum every
Hot infusion tube (10.5) is connected on liquid nitrogen state separator (10.4), and the welding wire on welding wire wheel (8.13) is also from through-hole
(8.12) welding wire feeding wheel (8.38) are connected to and reach welding gun (8.3) top position across welding wire guide sleeve (8.36)；Flexible servo
Hydraulic cylinder (2.3) ejection piston seal plate (2.2) returns in welding vacuum chamber (2), starts argon arc welder (8), and when welding is cold
But cover lifting hydraulic cylinder (7.16) pushes up above lower cooling dome (7.15) to welding workpiece, the partition of starting weldering fume purifier (8.2)
Cylinder (8.23) retracts, and the smog for welding generation is net by expansion corrugated pipe (7.18) connection smoking pipeline (8.21) inspiration weldering cigarette
Change device (8.2) to be handled, while welding gun cooler II (8.39) is passed through liquid nitrogen Butt welding gun and is cooled down；
5) after equipment completes welding, welding workpiece enters weld seam from the conveyer belt (9.2) that vacuum chamber is transmitted to outside
Detection device (9), the supporting cylinder (9.12) of conveyer belt (9.2) bottom jack up welding workpiece and are detached from conveyer belt (9.2) surface,
The fixed compression hydraulic cylinder (9.10) in conveyer belt (9.2) side and overturning hydraulic motor (9.11), which are withstood, clamps welding workpiece two
End, supporting cylinder (9.12) retraction make hanging in the middle part of welding workpiece, starting detection host (9.7) and rotating electric machine (9.1) band
Dynamic testing stand (9.3) rotate, and the detection probe on testing stand (9.3) issues on detection signal to welding workpiece and feeds back to detection
Host (9.7), overturning hydraulic motor (9.11) cooperates rotated simultaneously when detection, drives welding workpiece to rotate simultaneously, makes to examine
It is more comprehensive to survey position；If detection is off quality, it is driven again into vacuum chamber and carries out repair welding.
