Description
Technical field
The invention belongs to welding material of metal technical fields, and in particular to a kind of safe welding rod of low spatter type.
Background technology
Welding is the system of a kind of jointing metal in a manner of heating, high temperature or high pressure or other thermoplastic materials such as plastics
Make technique and technology.Electric welding is one kind of welding technique, and electric welding can be not only used for carrying out metalwork connection, can also be to metal
Part surface is modified, and to obtain the cladding layer of the required properties such as wear-resisting, heat-resisting or corrosion-resistant, welding technique is extensive
Applied to industrial circles such as mine, metallurgy, agricultural machinery, building, railway, oil and chemical industry, there is high economic and social benefit.
Fusing is filled in the metal strip of weldment junction when welding rod is electric welding, mainly by core wire and external welding agent layer structure
At according to the difference of function and usage and application places and welding procedure, welding rod is segmented into multiple and different types.The weldering of welding rod
Medicine complicated component, type is various can be applied in different weldments, play the stability for improving arc burning, and protection welding is molten
Pond ensures weld seam deoxidation, desulfuration phosphorus impurities, and alloys producing is supplemented for weld seam.But molten alloy temperature when due to welding
Degree is higher, the problem of welding slag splashes is being easy to happen, using different welding agent since temperature difference is larger with weldment contact
Its splashing of welding rod degree it is different, but welding slag splashing is not avoided that.Welding slag splashes may be to the body of welding operating personnel
Body health damages, it is also possible to cause the harm such as fire in welding place.
Invention content
In view of the above problems, the purpose of the present invention is to provide a kind of safe welding rod of low spatter type, which was using
Welding slag splashing degree is very small in journey, and welding quality is good, and very safe using process.
A kind of safe welding rod of low spatter type, the welding rod are wrapped in the first welding agent layer and on core wire by core wire and successively
Two welding agent layers are constituted.
Wherein, according to mass fraction, the ingredient of the first welding agent layer includes：30-40 parts of high carbon ferro-chrome, mid-carbon fe-mn 5-10
Part, 15-20 parts of tungsten carbide, 8-10 parts of nickel powder, 2-3 parts of rutile, 1-4 parts of ferrosilicon, 4-6 parts of vanadium iron, 1-3 parts of magnesia, fluorite
2-3 parts, 0.4-0.8 parts of fluoride, 20-25 parts of bonding agent.
The ingredient of second welding agent includes：60-70 parts of rosin, 8-15 parts of vaseline, 2-5 parts of hydroabietyl alcohol, succinic acid 4-7
Part, 1-2 parts of diethanol amine, 1-3 parts of surfactant.
Preferably, according to mass fraction, the ingredient of the first welding agent layer includes：34-36 parts of high carbon ferro-chrome, mid-carbon fe-mn 7-8
Part, 17-19 parts of tungsten carbide, 8-9 parts of nickel powder, 2-2.5 parts of rutile, 1-2 parts of ferrosilicon, 4-5 parts of vanadium iron, 2-3 parts of magnesia, fluorite

6 parts, 1.5-2 parts of diethanol amine, 2-3 parts of surfactant.
The technical thought of the present invention is the second welding agent layer to be arranged by the outer layer in welding agent, the second welding agent layer choosing selects use
The substances such as rosin and vaseline are made, when being welded, due to the effect of electric current, and the alloy in core wire and the first welding agent layer
By heating and melting be attached to weldment surface formed weld seam, wherein welding slag etc. due to being contacted with the substance of the second welding agent layer, wherein
Partial heat be pulled away, and lead to the heated volatilization of the second welding agent layer segment substance, after the temperature of welding slag reduces, splashing journey
Degree is reduced.In addition, since part the second welding agent layer substance fails to volatilize completely, forms melt substance and closed with welding slag and welding
Gold is fallen, and in welded joints, the density of the second welding agent layer substance is relatively low therefore can form top layer in face of weld for attachment
Protective layer can improve the quality of weld seam, and carry out cladding and adhesion to substances such as welding slags, further decrease welding slag splashing
Degree.
Second welding agent layer substance will not be blended in inside welding alloy in the welding process since fusing point and boiling point are relatively low,
The weld seam welding quality of weldment is impacted, the second welding agent layer substance will only adhere to the top layer of weld seam.
Preferably, in the welding rod, the thickness of the first welding agent layer is 7-10 times of the second welding agent layer thickness.Second welding agent layer
Content it is relatively low, while can playing a role, do not interfere with the normal use of welding rod, when the second welding agent layer is blocked up, due to
It, which is taken away too many heat and influences oxygen, enters inside welding rod, it is willing can cause welding rod cannot the normal starting the arc, two outer second welderings
The welding quality that weldment can be also influenced in alloy is penetrated into after medicine melting.
Preferably, the fluoride in the first welding agent layer is one kind in calcirm-fluoride, sodium fluoride and potassium fluotitanate.Fluoride
It uses, the crystal grain thinning of weld metal can be improved, change inclusion morphology, improve welding quality.
Preferably, the bonding agent used in the first welding agent layer is potassium water glass or sodium silicate.
Preferably, the surfactant in the second welding agent layer is silicone based surfactant or fluorocarbon surfactant.
Surfactant can reduce the surface tension of welding agent, improve the wetability and solderability of welding agent, play the protection of the second welding agent
Performance.
Preferably, the granularity of each ingredient is more than 80 mesh in the first welding agent layer.Each material composition in first welding agent layer
Granularity is smaller, and the degree that welding slag splashes is lower, and by lowering the grain size of welding agent raw material, welding slag splashes when can also reduce electric welding
Degree.
Wherein, the welding agent preparation method of the second welding agent layer is：According to mass fraction, rosin and vaseline are added to
In reaction kettle, 140 DEG C are heated to be completely melt up to rosin, then by hydroabietyl alcohol, succinic acid, diethanol amine and surface
Activating agent is added in reaction kettle, is stirred continuously each component to being completely dissolved and being uniformly mixed, and obtains required second welding agent.
A kind of safe welding rod of low spatter type provided by the invention has the following advantages compared with prior art：
First welding agent layer choosing of the welding rod welding agent of low spatter type, all welding agent components have selected granularity smaller
Material can reduce the possibility for welding slag splashing occur；The second welding agent layer choosing ingredients such as rosin vaseline, these materials are welding
When connecing, the ability that can reduce welding slag by absorbing heat prevents welding slag from splashing on a large scale.In addition, since the second welding agent of part is inhaled
It is attached to welding slag surface, leads to the degree of adhesion bigger between welding slag, to further improve the spattering problem of welding process.
Second welding agent layer is in addition to improving spattering problem, additionally it is possible to after the cooling period, form protective layer outside weld metal, ensure
Weld seam deoxidation prevents weld seam alloy from oxidation or corrosion occurs, improves the quality and stability of welding.
