By welding a waveguide induction heater and selecting solder flux and welding process parameters, brazing temperature can be precisely controlled between 577 DEG C and 585 DEG C, and induction brazing semi-automatic welding of the aluminum waveguide and the flange is achieved. Welding parameters of the novel technology are automatically controlled through equipment, and the waveguide can be welded by just one single person. Compared with traditional manual flame brazing, labor intensity and skill requirements of an operator are reduced, and product quality and work efficiency are greatly improved. The technological method is suitable for brazing of aluminum waveguides and flanges of various types.
Description
Technical field
The invention belongs to welding manufacture technical field, relate to a kind of Welding method of aluminium alloy flange dish and aluminium alloy waveguide tube, be specifically related to the Welding of aluminium alloy flange dish and aluminium alloy waveguide tube in the waveguide device manufacture process of radar microwave product.
Background technology
As microwave regime antenna system important composition part, aluminium alloy waveguide all achieves mechanization, automation in the operation such as machining, detection, but in the welding of aluminium waveguide and ring flange, domesticly still rest on the process using Manual flame soldering.Its technological process is: cleaning before the weldering of ring flange and waveguide, the assembling of flange and waveguide, Manual flame soldering, postwelding cleaning etc.Cleaned ring flange is assemblied on waveguide by pincers worker, and parts fixation is in frock, and the hand-held welding gun of welder one, a hand-held welding wire, back and forth gives part homogeneous heating.Welder rule of thumb judges the temperature of part, and then add solder and solder flux, welder observes soldering part in the process always, labour intensity is very large, notice high-pressure, easily causes fatigue and injury to eyes, and the wayward burning often causing part of Flame Heating Temperature.The method needs two people's compounding practices, also can only complete single-piece production at every turn, and fatigue resistance is large, production efficiency is low, welder observes flame for a long time and easily damages welder's eyes, difficult quality guarantee.
In recent years, aluminium waveguide production and processing amount sharply rises, and manual soldering becomes the bottleneck problem in production process, brings very large pressure to production.The defect existed in prior art or deficiency have the following aspects:
(1) manual single-piece is produced, and welder's labour intensity is very large, and in welding process, welder observes part and flame always, easily causes fatigue and injury to welder's eyes.
(2) in welding process, aluminium soldering temperature and fusion temperature have a narrow range of temperature, general about 50 DEG C, welder's notice high-pressure, and welder's skill set requirements is high, easily causes the defects such as burning, make quality unstable.
In a word, prior art work fatigue resistance is large, production efficiency is very low, skill set requirements is high, easily damage welder, difficult quality guarantee.
According to investigations, current home and abroad does not also have aluminium alloy waveguide induction brazing technique to report, aluminium alloy waveguide tube and the induction brazing of aluminium alloy flange dish are in a leading position level undoubtedly at home.
Summary of the invention
The technical problem solved
In order to avoid the deficiencies in the prior art part, the present invention proposes a kind of Welding method of aluminium alloy flange dish and aluminium alloy waveguide tube.
Technical scheme
A Welding method for aluminium alloy flange dish and aluminium alloy waveguide tube, is characterized in that step is as follows:
Step 1: clean oil removing before aluminium waveguide and the soldering of aluminium ring flange;
Step 2: apply soldering paste 190PA on the installation mating surface of ring flange and waveguide, ring flange is sleeved on waveguide;
Step 3: induction heater is placed in above the solder side of ring flange and waveguide, distance is 3.5 ~ 4.5mm; Described induction heater adopts copper pipe coiling, and above solder side, copper pipe turns to the structure that matches with ring flange and is greater than the size of ring flange;
Step 4: pass into induction heater welding current 50A, 33 ~ 37 seconds weld intervals, welding completes.
The caliber of described copper pipe is 6mm, and wall thickness is 1mm.
Beneficial effect
The Welding method of a kind of aluminium alloy flange dish that the present invention proposes and aluminium alloy waveguide tube, by the induction heater of jointing waveguide, select solder and flux and welding condition, can more accurately brazing temperature be controlled between 577 DEG C ~ 585 DEG C, achieve aluminium waveguide and ring flange induction brazing semi-automation welding.This new technology welding parameter is controlled automatically by equipment, and the single welding job that just can complete waveguide, compares traditional-handwork gas brazing, reduces operator's labour intensity and skill set requirements, has increased substantially product quality and operating efficiency.Process in the present invention is applicable to aluminum waveguide and the ring flange Welding of each model.
Beneficial effect of the present invention is as follows compared with the conventional method: part only need be installed on workbench by operator, is coated with solder, arranges welding parameter, and starting device welds, and can complete, thus labour intensity reduces greatly, and skill set requirements also reduces.
