Abstract
The invention provides a device inhibiting welding defects of a small-diameter aluminum alloy guiding pipe. The device inhibiting the welding defects of the small-diameter aluminum alloy guiding pipe can be applied to welding of small-diameter aluminum alloy guiding pipes of a spacecraft or in other fields.
Description
Technical field
The present invention relates to a kind of auxiliary welding equipment, in particular, it is related to a kind of suppression minor diameter aluminum alloy conduit
The device of weld defect.
Background technology
Minor diameter aluminum alloy conduit is generally light-wall pipe, the method that argon tungsten-arc welding is adopted its butt welding more.Due to size
Limit, the typically no support in workpiece back, while welding condition scope is narrower, therefore easily form weld blowhole, lack of penetration
With the defect such as misalignment.
The content of the invention
The present invention will improve minor diameter aluminum alloy conduit assemble welding, increase welding condition scope, suppress welding to lack
Fall into and occur.
It is critical only that for the present invention increase inner support in conduit welding position.
The material for making inner support is the fluorine-containing activating agent that aluminum alloy melting weldering can be used；The general ratio of inner support diameter is led
The little 0.1-0.3mm of bore, is advisable with being positioned over formation tight fit during guide pipe inner hole；The thickness of inner support is greater than weld seam width
Degree, is advisable with 4-5mm；Immediately below conduit docking location, whole circle circular arc weldering bakie is opened up on inner support is cylindrical, bakie width is welded
Degree is not more than 0.5mm less than weld width 1-2mm, depth；Open up on inner support is cylindrical several gas vents connection weldering bakies with
The external world, gas vent are circumferentially generally 1mm or so, are radially not more than 0.5mm.
The inner support as made by above-mentioned condition, in assemble welding pair in be placed in catheter interior, can fit in welding process
Work as high current, in making the uniform heavy bakie with weldering of weldering leakage.Can be carried out using the method such as solid, liquid, gas pair of interior support after the completion of welding
Cleaning.
The beneficial effects of the present invention is：
1) increased inner support to improve assembling effect, reduce misalignment defect and produce to being increased constraint by weldering conduit.
2) weldering bakie is formed with inner support, molten metal can be formed and be supported, therefore electricity can be suitably increased when welding
Stream, contributes to the gas effusion in molten bath, reduces the generation of gas hole defect, while the formation for welding leakage can reduce incomplete penetration defect
Generation.
3) inner support is made up of the fluorine-containing activating agent that Welded can be used, and the metal that high temperature is contacted during welding melts
Liquid, can be reacted with hydrogen therein and form hydrogen fluoride discharge, contribute to eliminating weld blowhole.
4) inner support weldering bakie is provided with gas vent, discharges can the gas that heated up by weld heating in weldering bakie, just
Well shape in weld seam back.
Description of the drawings
Fig. 1 is that a kind of operation principle of the device of suppression minor diameter aluminum alloy conduit weld defect that the present invention is provided is illustrated
Figure.
Fig. 2 is a kind of schematic cross-section of the device of suppression minor diameter aluminum alloy conduit weld defect that the present invention is provided.
Specific embodiment
Embodiment of the present invention is illustrated below in conjunction with the accompanying drawings, in accompanying drawing 1：1 be conduit A, 2 be conduit B, 3 be inner support, 4
To weld bakie, 5 is gas vent.
Specific embodiment is as follows：
1) activating agent that can be used using Welded makes the inner support 3 in accompanying drawing 1, and diameter is typically little than catheter diameter
0.1-0.3mm；Width is more than weld width 4-5mm；4 width of weldering bakie is less than weld width 1-2mm, and depth is not more than 0.5mm,
For circular arc；Open up gas vent 5 some, gas vent 5 is circumferential to be generally 1mm or so, is radially not more than 0.5mm.
2) conduit A1 and conduit B2 interfaces make perpendicular cuts face, and conduit A1, conduit B2 and inner support 3 are pressed accompanying drawing 1
Shown centered assembling.
3) preliminary filling protective gas inside dummy pipe is welded, then starts welding.
4) inner support 3 is removed after the completion of welding, the method such as solid, liquid, gas may be used individually or jointly during removing, is removed
Method is illustrated：As hard thing is tapped, gases at high pressure, liquid extrusion etc..
After removing inner support 3, as needed catheter interior is cleared up.
