Description
Technical field
The invention belongs to process coating technology field, especially a kind of process in aluminium welding wire ti coat on diamond.
Background technology
It is right as aluminium welding wire and high-efficient automatic technology are in the utilization of every profession and trade, the particularly high-end field such as space flight and aviation
The quality and performance requirement of aluminium welding wire are higher and higher.The quality of aluminium welding wire depends not only on the melting of aluminium welding wire, while also depends on
Forming and surface treatment in aluminium welding wire, traditional aluminium welding wire processing technology are that thick raw material are pulled to trimmed size
Afterwards, it was the chemical cleaning used in the past by removing the dirt such as lubricant on surface, the methods of mechanical scraping, this kind of method exists
The defects of welding wire surface forms pit, oxide etc., have impact on surface quality, and easily weld seam produces stomata in welding process.
Meanwhile titanium easily generates dystectic oxidation titanium inclusion in smelting process, research shows, titanium oxide and molten aluminum
Between when infiltrating angle and being less than 90 degree, being not easy to float removes, and titanium oxide contacts well with molten aluminum, therefore titanium oxide type dross thing is led
Hot good, molten aluminum can be set on dross thing because temperature declines, so as to aggravate the degree of dross.So smelting the aluminium of titaniferous
During liquid, submersed nozzle easily blocks, and will deteriorate molten aluminum quality, it is also possible to cause production disruption.So it also limit aluminium welding wire
In titaniferous amount.
The content of the invention
It is more preferable present invention aims at a kind of welding performance and Weld Performance is provided by a kind of new manufacturing process
Aluminium welding wire.
The concrete scheme that the present invention uses for：
Cotton thread containing titanium elements is wrapped in aluminium welding wire surface, auxiliary agent is attached to foregoing winding to auxiliary agent is added dropwise thereon
There is the aluminium welding wire surface of the cotton thread containing titanium elements, treat that the cotton thread is completely withdrawn from aluminium welding wire and the auxiliary agent on aluminium welding wire surface is waved
After distributing entirely, the aluminium welding wire after processing is polished to obtain the aluminium welding wire of surface cladding titanium,
Wherein, the cotton thread containing titanium elements is wrapped in aluminium welding wire surface and is wound to slide：I.e. cotton thread controls one by equipment and puts
Line, a take-up, in the state twitched while being wrapped in aluminium welding wire surface with tensioned state, forward pull is when tightening
10N, backward pull 15N, the speed for twitching cotton thread are 25 cm per minutes,
As preferred：Welding wire is also to control a unwrapping wire, a take-up by equipment, in the state twitched,
Cotton thread and welding wire are all movements, both can control the big of aluminium welding wire ti coat on diamond amount by governing speed
It is small, but the titanium on cotton thread surface be covering up, bonding force loosely, individually improves the speed twitched of cotton thread to adjust titanizing amount
Being scattered for titanium is easy to cause, so the take-up speed of welding wire is preferably improved,
In the present invention, welding wire wire travelling speed, i.e. titanizing speed are reduced to by 5m/s to 12m/s, titaniferous amount by 0.15%
0.05%, the rate of addition of kerosene is constant, or 4 ml/mins,
Wherein, internal layer is strong fibrous layer in the cotton thread containing titanium elements, and outer layer is cotton layer, and the surface of outer layer cotton layer covers
Titanium valve, preparation process are：Titanium valve is tuned into paste with aviation kerosine, cotton thread is coated on cotton thread by pastel, pastel,
Obtain being coated with the cotton thread of titanium elements after aviation kerosine volatilization,
As preferred：The auxiliary agent of dropwise addition is aviation kerosine, alcohol or isobutanol, and rate of addition is 4 ml/mins, these
Auxiliary agent can vapor away in 1 minute after having titrated from welding wire, easy to operate without heating,
Wherein, polishing operation, by polishing, makes titanium combine closely with aluminium to be polished using diamond mould.
The beneficial effects of the present invention are：
In the production process, the cotton thread containing titanium elements is wrapped on welding wire, titrates auxiliary agent, titanium is uniformly attached to welding wire
Surface, can fill up the surface such as pit produced in drawing process unfavorable condition comprehensively, and it is attached farthest to eliminate tradition plating
Uncertain influence in technique, and the attached amount of plating that welding wire surface titanium greatly improved；
Welding wire surface contains titanium elements, when being welded with identical Current Voltage, spatter smaller, and micro titanium
Weld grain can be refined, bubble is prevented and improves the quality of weld seam and improve its mechanical performance, so applying titanium welding wire
Welding performance and Weld Performance are more preferable；
Aluminium welding wire surface applies titanium, and solving titanium and molten aluminum, melting is also easy to produce the phenomenon of nozzle blocking together, realizes technique
Simply, it is easy to operation.
Embodiment
The titanizing aluminium welding wire obtained with method for coating of the welding wire of common ER5087 more than, welding wire surface contain
The titanium of (accounting for welding wire gross weight after titanizing) 0.05~0.15% (is converted into TiO2Numerical value)；
The welding wire surface roughness range that the present invention coats is thinner, can make 5 mean roughness of welding wire surface 0.05~
0.15 μm of scope.The difference range of every 2 vickers hardness hvs 10 of welding wire surface is within 50.It is so electric with identical electric current
Pressure is when being welded, Wire Performance more preferably, spatter smaller.By increasing Ti content, weld grain can be refined, prevents from producing
Anger bubble and the quality and its mechanical performance of raising for improving weld seam.So welding performance and the Weld Performance ratio of titanizing welding wire are common
Aluminium welding wire is more preferable, while avoids and add titanium elements in smelting, causes the dross phenomenon containing titanium elements, blocks the mouth of a river, technique letter
It is single, easy to containing high titanium aluminium welding wire industrial applicability.
