Description
Technical field
The present invention relates to the solder technology of large workpiece copper and copper, being specially a kind of cable bus opening heating collar for powering and the application in the welding of cable bus copper pipe thereof.
Background technology
In brazing connects in the past, copper has the characteristics such as excellent electric conductivity, thermal conductivity, corrosion resistance, ductility and certain intensity.Be used widely in electric, electronics, chemical industry, food, power, traffic and aerospace industry.In fine copper (red copper), add more than 10 plant alloying element, form all kinds of copper alloys of solid solution, if zincification is brass; Adding nickel is copper-nickel alloy; Adding silicon is silicon bronze; Adding aluminium is aluminium bronze etc.
Copper and its alloy can realize connecting by the process such as soldering, electric resistance welding, at today, the melting welding dominate of industry prosperity.The welding of Copper and its alloy is easily realized by processes such as SMAW, TIG weldering, MIG welderings.
1, the method for welding red copper has the methods such as gas welding, manual carbon arc welding, manual electric arc welding and manual argon arc welding, and large scale structure also can adopt automatic welding:
(1) what the gas weld joint red copper of red copper was the most frequently used is banjo fixing butt jointing, and lap joint and T-joint are as far as possible few to be adopted.Gas welding can adopt two kinds of welding wires, and a kind of is welding wire containing deoxidant element, as silk 201,202; Another kind is general copper wire and the slitting of mother metal, adopts gas agent 301 to make flux.Neutral flame should be adopted during gas welding red copper.
(2) the manual electric arc welding edge of red copper, when weldment thickness is greater than 4 millimeters, necessary preheating before weldering, preheat temperature is generally at about 400 ~ 500 DEG C.With the welding of copper 107 welding rod, power supply should adopt DC reverse connection.Should use short arc during welding, welding rod should not do teeter.Reciprocal rectilinear motion made by welding rod, can improve the shaping of weld seam.Long weld seam should adopt backstep welding.Speed of welding should be tried one's best hurry up.During multilayer welding, necessary slag thoroughly between scavenger layer.
Welding should be carried out in draughty place, to prevent copper poisoning phenomenon.Postwelding application butt hammer knocks weld seam, eliminates stress and improves weldquality.
(3) manual argon arc welding of red copper is when red copper manual argon arc welding, and the welding wire of employing has silk 201 (special red copper welding wire) and silk 202, also adopts copper wire, as T2.Oxide-film, the wet goods foul of tackling workpiece welding edge and welding wire surface before weldering all must be cleaned out, and avoid producing the defect such as pore, slag inclusion.The method of cleaning has mechanical method of cleaning and soak cleaning method.When banjo fixing butt jointing thickness of slab is less than 3 millimeters, square groove; When thickness of slab is 3 ~ 10 millimeters, open double V-groove, bevel angle is 60 ~ 70 & ordm; ; When thickness of slab is greater than 10 millimeters, open X-type groove, bevel angle is 60 ~ 70 & ordm; ; Lack of penetration for avoiding, generally do not stay root face.According to thickness of slab and groove size, the fit-up gap of banjo fixing butt jointing is chosen within the scope of 0.5 ~ 1.5 millimeter.Red copper manual argon arc welding, normally adopts straight polarity direct current, and namely tungsten electrode connects negative pole.In order to eliminate pore, ensureing that the root of weld fuses and through welding reliably, must speed of welding be improved, reducing argon gas consumption, and preheating weldment.When thickness of slab is less than 3 millimeters, preheat temperature is 150 ~ 300 DEG C; When thickness of slab is greater than 3 millimeters, preheat temperature is 350 ~ 500 DEG C.Preheat temperature is unsuitable too high, otherwise the mechanical performance of welding point is reduced.Also have the carbon arc welding of red copper, the electrode that carbon arc welding uses has carbon electrode and graphite electrode.Red copper carbon arc welding welding wire used is the same with during gas welding, and also can cut bar with mother metal, the flux of available gas welding red copper, as gas agent 301 etc.
(4) ratio-frequency welding is high-frequency induction heating again, and ratio-frequency welding utilizes 10 ~ 500KHz high frequency electric to flow through metal joint face produce resistance heat and apply a kind of welding method that (or not applying) pressure reaches corrupt split.Be characterized in: speed of welding is large, and welding heat affected zone is little, welds and can not clear up workpiece, can weld light-wall pipe, solderable metal pipe, very relatively good to magnetic conductive metal welding, copper is magnetic conduction not.
(5) soldering high temperature furnace welding: can only small workpiece be welded, can not welding be moved.
