Method, the part welding processing for below 1mm thin-walleds not uniform thickness.
Technical background
Thin-walled especially wall thickness is less than 1mm thin-walled not uniform thickness product, and vacuum electron beam welding is vacuum electron beam welding
Difficult point, due to wall thickness, and be thin-walled, the thin-walled parts to be welded of different wall are to electron beam quite sensitive, easily
The problem of occurring one of part burn-through or not prison welding, it is domestic as the difficult point for not waiting the welding of wall thickness thin-walled parts
All tackled key problems outside in input strength, but due to reasons such as technical know-how, technology restrictions, it is not disclosed always.
Present invention
For break-through skill bottleneck, the predicament of original production inefficiency is solved, the present invention provides a kind of thin-walled not uniform thickness vacuum
Electron beam welding processing method, which is realized, can apply to the efficiently production of industrial processes batch.
Technical scheme：A kind of thin-walled not uniform thickness part vacuum electron beam welding processing method, the part includes
Light-wall pipe and end cap, end cap are located at light-wall pipe side, comprise the following steps：
Step 1：Design welding junction pattern：Light-wall pipe controls the model in 0.04mm~0.08mm with the bilateral gap X of end cap
In enclosing；Thin-wall Tube open height is higher by end cap outerplanar h=0.1mm；
Step 2：Vacuum electron beam welder is opened, the device parameter of vacuum electron beam welder is set：Speed 6m/s, voltage
60 kilovolts, focus on 0.62A, line 3.5A, welding gun and the welding chamber vacuum values are respectively 1 × 10-3Pa and 9 × 10-2Pa, weld interval
5s；
Step 3：Load onto light-wall pipe 1 and end cap 2；
Step 4：The welding chamber door is closed, startup vacuumizes button, the welding chamber is vacuumized with welding gun automatically；
Step 5：Treat that vacuum reaches signal prompt, press line button, start the mouth of pipe of electron beam alignment light-wall pipe 1 and end
The binding site of lid 2 carries out welding processing；
Step 6：Weld interval terminates, and the welding chamber is inflated, and opens the welding chamber, takes out welding product.
To be easily worked, more excellent processing effect is realized, the above-mentioned cylindrical sharp edge of welding end cap interior outside chooses different processing
Radian, welding end cap inner face sharp edge radian R1 is that sharp edge radian R2 is 1 outside 0.2, end cap.
Advantageous effects：The present invention solves the predicament of original production inefficiency, and realizing one kind can be less than to wall thickness
The welding of 1mm thin-walled parts, the problem of solving batch production realizes the industrial high efficiency batch production of product.
