Description
Technical field
The invention belongs to welding technology field, be specifically related to the welding method of radio-frequency cavity height electric-force gradient region cooling water channel。
Background technology
During radio-frequency cavity body running, its high electric-force gradient region is owing to electric current density is high, heating is serious, significantly impact the normal operating parameters of radio frequency cavity, therefore this high electric-force gradient region is cooled down, the mode of cooling is usually welds cooling water channel at this gradient region, but to avoid the adverse effect that vacuum environment about causes by the welding of cooling water channel as far as possible。
The cooling water channel welding in conventional radio-frequency cavity height electric-force gradient region all adopts the method for money base soldering to carry out, but owing to money base Welding temperature is higher, radio frequency cavity mostly is thin-wall construction, during welding, cavity can produce high temperature deformation, especially when welding region complicated structure, can cause welding region in welding process because the uneven deformation produced of being heated cannot be eliminated by postwelding shaping or secondary operations, thus directly resulting in the failure of radio frequency cavity welding。In existing open source literature, but without seeing the other kinds of welding method suitable in this region。Therefore it is badly in need of finding a kind of welding requirements that disclosure satisfy that this gradient region and the welding method of Wall deformation being prevented effectively from。
Summary of the invention
(1) goal of the invention
According to problems of the prior art, the invention provides and a kind of can make radio-frequency cavity height electric-force gradient region good cooling results, do not affect vacuum and effectively reduce the welding method of radio-frequency cavity body deformability。
(2) technical scheme
In order to solve the problem existing for prior art, technical scheme is as follows:
The welding method of radio-frequency cavity height electric-force gradient region cooling water channel, it is critical that the method comprises the following steps:
(1) welding region of workpiece to be welded is polishing to be completely exposed metal true qualities, and cleans the greasy dirt on welding region surface, chip；
(2) heat workpiece to be welded and to 225～235 DEG C and keep constant temperature, process at its welding region uniform application scaling powder and to welding region tining；
(3) being fitted together by workpiece to be welded, closure is jointly heated uniformly to 225～235 DEG C and keeps constant temperature behind termination, carries out low temperature soldering；
Preferably, the described tining in step (2) is to hang silver stannum, and the ratio that wherein silver accounts in silver stannum is 3%～5%(percetage by weight)。
Preferably, step (2) heats workpiece to be welded controlled by electronic thermostatic controller to 225～235 DEG C and monitor。
Preferably, step (2) heats the welding region tining treating welder's part when workpiece to be welded is 230 DEG C to process。
Preferably, workpiece to be welded is fitted together in (3) by step, and closure is heated uniformly to 230 DEG C behind termination jointly。
Preferably, also at the gap location of two to be welded absorption surface adding scolding tin in after being fitted together by workpiece to be welded in step (3), constantly vibrations welding workpiece makes the bubble between workpiece overflow simultaneously, until scolding tin fills up whole gap。
Preferably, the alloy that material is rustless steel, copper or copper of workpiece to be welded in step (1)。
(3) beneficial effect
What technical scheme provided by the invention adopted is that the cooling water channel of radio frequency cavity gradient region is welded by the method for soldering, has following advantage:
(1) welding temperature of soldering is low, can be prevented effectively from the deformation that cavity produces because of high temperature；
(2) what solder was selected is not common scolding tin, but silver-tin solder, because silver-tin solder is higher than the intensity of ordinary solder, electric conductivity better, the requirement to electric conductivity of the radio-frequency cavity height electric field region can be met；And the impurity of silver-tin solder is few, the requirement to fine vacuum and high-cleanness environment of the radio frequency cavity can be met。
(3) in the process carrying out low temperature soldering, the gap location at two absorption surface to be welded adds soldering, and constantly shakes workpiece to be welded the bubble between workpiece can be made to overflow, can be prevented effectively from the bubble high vacuum environment on radio frequency cavity and produce to affect。
Adopt welding method provided by the invention, it is possible to the simple and effective welding realizing radio-frequency cavity height electric-force gradient region cooling water channel。
