Technical field
The utility model belongs to petrochemical equipment welding field, is related to the welding of the tube sheet and heat exchanger tube of heat exchanger.
Background technique
The tube sheet of heat exchanger is flexible tube sheet in petrochemical equipment, and heat exchanger tube and two sides tube sheet are inner hole overlap joint fine melt
Saturating structure, such structure are a kind of exchanger tubes and tubesheets connection structure forms of new complete penetraction and fusion in welding, eliminate crevice corrosion, improve
Weld bond corrosion resistant degree of corrosion, antidetonation fatigue strength, can bear the Service Environments such as high temperature, high pressure；And there is stress at contact aperture
Collect medium and small, is not likely to produce the advantages such as root of joint crackle.It is each to design because the various advantages of such welding point connection structure are significant
Institute has gradually started the welding point using this structure type in the design.It needs when exchanger tubes and tubesheets weld by certainly
It is molten to make root full penetration, but design requirement is not achieved from molten rear weld strength, it is necessary to root is increased by landfilling area and welds meat, enhancing
Weld strength is to reach design requirement.But it is off currently, there are no can be used for such welded joint structure form in the market
Argonaut welding welding machine fill silk pipette tips.
Summary of the invention
We will solve the problems, such as: filling up prior art blank, invent a kind of the interior of exchanger tubes and tubesheets overlap joint connection
Hole argonaut welding welding machine silk filling pipette tips.
The utility model provides a kind of pipe and tube sheet overlapped inner hole argonaut welding welding machine and fills silk pipette tips, and structure has
Copper core 1, ceramic jacket 2, steel wire 3, tungsten electrode fixing head 4, tungsten electrode 5, positioning sleeve 6, ceramic fixing head 7；The tungsten electrode fixing head 4
And steel wire 3 is assembled in copper core 1；The ceramic jacket 2 is assembled in copper core 1；6 outer diameter of positioning sleeve is than heat exchanger tube
The small 2mm of internal diameter is assembled in ceramic jacket 2 and copper core 1；The ceramic fixing head 7 is tightened in copper core 1.
The application method of the inner hole argonaut welding welding machine silk filling pipette tips of exchanger tubes and tubesheets overlap joint connection:
1. when exchanger tubes and tubesheets inner hole welding of rapid cooling, first carrying out bottom welding from molten pipette tips with inner hole welding machine, making heat exchanger tube
With tube sheet overlapping part root full penetration, and make exchanger tubes and tubesheets lap-joint weld seam rounding off；
2. the argonaut welding welding machine silk filling pipette tips of assembled exchanger tubes and tubesheets inner hole overlap joint connection are passed through top
The wire hole at center is connected on welder head 8；
3. determining the depth that pipette tips put in tube sheet according to pore depth using the preceding depth for first measuring the pore that exchanges heat on tube sheet
It spends and makes a mark in pipette tips, make tungsten electrode and welding wire just at position while welding；
4. being programmed positioning on argon arc welding automatic welder, welding machine parameter is adjusted by welding procedure and carries out welding；
5. carrying out filler wire welding using inner hole welding machine silk filling pipette tips, increases welding angle height by filling silk, make welding point
Intensity reaches design requirement.
The utility model for heat exchanger tube and two sides tube sheet be inner hole overlap full penetration structure welding provide it is essential
Powerful so that automation is realized in the internal bore welding welding of exchanger tubes and tubesheets overlap joint connection, and structure is simple, manufacture at
This is low, and operation is easy, and improves production efficiency.
Detailed description of the invention
Fig. 1 is the inner hole argonaut welding welding machine silk filling pipette tips main view of exchanger tubes and tubesheets overlap joint connection
Fig. 2 is that argonaut welding welding machine silk filling pipette tips are installed to progress welded pipe head on welding machine
In figure: 1 copper core, 2 ceramic jackets, 3 steel wires, 4 tungsten electrode fixing heads, 5 tungsten electrodes, 6 positioning sleeves, 7 ceramic fixing heads, 8 welderings
Machine head, 9 tube sheets, 10 heat exchanger tubes.
Specific embodiment
Now in conjunction with attached drawing, the utility model is further illustrated.
The pipette tips as shown in Figure 1, pipe and tube sheet overlapped inner hole argonaut welding welding machine fill silk, structure have copper core 1, ceramics
Set 2, steel wire 3, tungsten electrode fixing head 4, tungsten electrode 5, positioning sleeve 6, ceramic fixing head 7；The tungsten electrode fixing head 4 and steel wire 3
It is assembled in copper core 1；The ceramic jacket 2 is assembled in copper core 1；6 outer diameter of positioning sleeve is smaller than the internal diameter of heat exchanger tube
2mm is assembled in ceramic jacket 2 and copper core 1, and positioning sleeve 6, which protrudes into heat exchanger tube, can effectively prevent in welding process shaking due to pipette tips
The dynamic inhomogeneities for causing weld seam；The ceramic fixing head 7 is tightened in copper core 1.
The inner hole argonaut welding welding machine silk filling pipette tips application method of exchanger tubes and tubesheets overlap joint connection is as follows:
1. when heat exchanger tube 9 and 10 inner hole welding of rapid cooling of tube sheet, first carrying out bottom welding from molten pipette tips with inner hole welding machine, making to exchange heat
Pipe and tube sheet overlapping part root full penetration, and make exchanger tubes and tubesheets lap-joint weld seam rounding off；
2. the argonaut welding welding machine silk filling pipette tips of assembled exchanger tubes and tubesheets inner hole overlap joint connection are passed through top
The wire hole at center is connected on welder head 8；
3. determining the depth that pipette tips put in tube sheet according to pore depth using the preceding depth for first measuring the pore that exchanges heat on tube sheet
It spends and makes a mark in pipette tips, make tungsten electrode and welding wire just at position while welding；
4. being programmed positioning on argon arc welding automatic welder, welding machine parameter is adjusted by welding procedure and carries out welding；
5. carrying out filler wire welding using inner hole welding machine silk filling pipette tips, increases welding angle height by filling silk, make welding point
Intensity reaches design requirement.
The utility model silk filling pipette tips are used cooperatively with internal bore welding from molten pipette tips, complete the weldering of exchanger tubes and tubesheets internal bore welding
