Description
Technical field
The present invention relates to the welding technique of big workpiece copper and copper, specially a kind of cable bus opening heating for being used to power
Circle and its application in the welding of cable bus copper pipe.
Background technology
In conventional brazing connects, copper has excellent electric conductivity, thermal conductivity, corrosion resistance, ductility and certain intensity
Etc. characteristic.It is used widely in electric, electronics, chemical industry, food, power, traffic and aerospace industry.In fine copper（It is purple
Copper）Alloying element is planted in middle addition more than 10, all kinds of copper alloys of solid solution is formed, if zincification is brass；It is copper-nickel alloy to add nickel；The silicon is added to be
Silicon bronze；Add aluminium for aluminium bronze etc..
Copper and copper alloy can use the processes such as soldering, electric resistance welding to realize connection, account for today, melting welding in industry prosperity
According to leading position.The welding of copper and copper alloy is easily realized with processes such as SMAW, TIG welderings, MIG welderings.
1st, the method for welding red copper has the methods of gas welding, manual carbon arc welding, manual electric arc welding and manual argon arc welding, large-scale knot
Structure can also use automatic welding:
（1）The gas weld joint red copper of red copper is most commonly used that banjo fixing butt jointing, lap joint and T-joint few use as far as possible.
Gas welding can use two kinds of welding wires, and a kind of is the welding wire containing deoxidant element, such as silk 201,202；Another kind is in general copper wire
With the slitting of mother metal, fluxing agent is made using gas agent 301.Neutral flame should be used during gas welding red copper.
（2）The manual electric arc welding edge of red copper, when weldment thickness is more than 4 millimeters, it must be preheated before weldering, preheating temperature typically exists
400~500 DEG C or so.Welded with the welding rod of copper 107, power supply should use DC reverse connection.Short arc should be used during welding, welding rod should not be made
Horizontal swing.Welding rod makees reciprocal linear motion, can improve the shaping of weld seam.Long weld seam should use backstep welding.Welding
Speed should be as far as possible quicker.During multilayer welding, it is necessary to thoroughly remove the slag of interlayer.
Welding should be carried out in draughty place, to prevent copper poisoning phenomenon.Postwelding application butt hammer taps weld seam, disappears
De-stress and improvement weldquality.
（3）For the manual argon arc welding of red copper in red copper manual argon arc welding, the welding wire of use has silk 201 (special red copper welding wire)
With silk 202, also using copper wire, such as T2.The foul such as the oxide-film of reply workpiece welding edge and welding wire surface, oil all must before weldering
It must clean out, the defects of avoiding producing stomata, slag inclusion.The method of cleaning has mechanical method of cleaning and soak cleaning method.Docking connects
When head plate thickness is less than 3 millimeters, square groove；When thickness of slab is 3~10 millimeters, double V-groove is opened, bevel angle is 60~70＆ordm；
When thickness of slab is more than 10 millimeters, X-type groove is opened, bevel angle is 60~70＆ordm；It is lack of penetration to avoid, root face is not stayed typically.Root
According to thickness of slab and groove size, the fit-up gap of banjo fixing butt jointing is chosen in the range of 0.5~1.5 millimeter.Red copper manual argon arc welding, lead to
It is often to use straight polarity direct current, i.e. tungsten electrode connects negative pole.In order to eliminate stomata, ensure the root of weld reliably fusion and through welding, it is necessary to
Speed of welding is improved, reduces argon gas consumption, and preheat weldment.When thickness of slab is less than 3 millimeters, preheating temperature is 150~300 DEG C；
When thickness of slab is more than 3 millimeters, preheating temperature is 350~500 DEG C.Preheating temperature is unsuitable too high, otherwise makes the mechanicalness of welding point
It can reduce.The also carbon arc welding of red copper, the electrode that carbon arc welding uses have carbon electrode and graphite electrode.Used in red copper carbon arc welding
Welding wire is as during gas welding, it is also possible to which mother metal cuts bar, can use the fluxing agent of gas welding red copper, such as gas agent 301.
（4）Ratio-frequency welding is called high-frequency induction heating, and ratio-frequency welding is to flow through metal connection using 10~500KHz high frequency electrics
Face produces resistance heat and applied（Or do not apply）Pressure reaches a kind of welding method of metal combination.It is characterized in:Speed of welding
Greatly, welding heat affected zone is small, and welding can not clear up workpiece, solderable light-wall pipe, solderable metal pipe, and very magnetic conductive metal is welded
It is relatively good, copper not magnetic conduction.
(5) soldering high temperature furnace welds：Small workpiece can only be welded, it is impossible to mobile welding.
Summary method：Above-mentioned welding method reaches institute's welding temperature, institute due to can not be heated in high-altitude to copper pipe
So that φ 120x φ 80mmT3 copper pipes can not be welded.
