Improve Weld Performance；
Manganese iron dust is in alloying constituent, for compensating in welding process the scaling loss of alloying element and to alloy necessary to weld seam transition
Element, to guarantee that weld metal obtains necessary chemical component and performance；
Reduction titanium, feldspar, cellulose and waterglass belong to arc stabilizer, and arc stabilizer can make welding rod in striking and welding process
Play the role of improving striking performance and stablize arc burning, be all the substance for being easy ionization, arc stabilizer mostly uses potassium, sodium, calcium
Compound, arc burning stability can be improved, and electric arc is made to be easy to ignite；
Reduction titanium, manganese iron, marble, rutile, feldspar, white clay, carclazyte, clay and mica these minerals belong to slag making
Agent generates slag protection liquid metal when welding and improves appearance of weld, after causing slag, mainly some oxides, and slag making
Agent dilutes slag, increases its activity；Wherein, feldspar is adjustable the physical property of slag and improves the acidity of slag, plays steady

Explanation is needed further exist for, it is whether scientific with quality proportioning in order to examine the raw material of technical solution of the present invention to choose
Rationally, inventor has carried out different comparative tests to the type and quality proportioning of each raw material:
Firstly, being adjusted to the quality proportioning of manganese iron, coating is made of the component of following proportion by weight:；Restore titanium
50 parts；15 parts of manganese iron；3.5 parts of carclazyte；3 parts of wood powder；2 parts of cellulose；6 parts of mica；8 parts of white clay；1.5 parts of clay；Marble 6
Part；5 parts of feldspar；Wherein, the content of manganese iron is 15 parts, and quality proportioning is higher than defined by the technical program 6-9 parts；According to above-mentioned
Proportion takes each component, bonding agent wet-mixing is added, mixed-powder is uniformly made, by mixed-powder extrusion on core wire, dried through high temperature
It is drying at welding rod；Detection discovery, the creep strength characteristics deterioration of welding metal are carried out to welding rod；The constantly content of adjustment manganese iron
It was found that manganese iron content is at 6-9 parts, the performance of welding rod and the intensity of welding metal and toughness are best.
Method similar to the above, which changes the proportion by weight of other several raw materials and tests manufactured welding rod, to be found, also
Former Ti content is excessively high to will cause extrusion difficulty, and welding plate temperature is excessively high, and slag is thinning, restores titanium proportion by weight in 50-60, also
Originality is good, arc stability, molten bath flat mirror, and deposition efficiency increases, and metal is fine mist transition, and electric arc is soft, and appearance of weld is beautiful,
Slag covers；Marble too high levels will increase the fusing point of coating, increases dry slag degree, causes speed of welding to slow down, easily make to weld
Seam generates inner air vent, and appearance of weld is coarse, and de- slag rate, spatter loss coefficient and power consumption are increase accordingly；Mica content is excessively high to can lead to medicine
Skin is loose excessively thick, the fragile head of welding rod and scratch, and electrode coating surface quality is poor；White clay too high levels are unfavorable for welding rod extrusion, make
Weld seam generates dry slag, increases weld seam hydrogen content, white clay content is too low to be easy to cause electrode coating to crack；Feldspar content is excessively high to be subtracted
Slow speed of welding increases slag viscosity；Thus prove that the proportion by weight of each raw material of technical solution of the present invention is scientific and reasonable.
Secondly, inventor replaces the raw material of electrode coating and has carried out two groups of comparative tests:
First group
Scheme one: 55 parts of titanium of reduction is taken；9 parts of manganese iron；2 parts of carclazyte；3 parts of wood powder；3 parts of cellulose；5 parts of mica；White clay 8
Part；3.5 parts of clay；7 parts of marble；4.5 parts of feldspar；

8 parts, 5 parts of mica, 7 parts of marble, 4 parts of feldspar；
Titanium dioxide and reduction titanium main component are titanium dioxide, and titanium dioxide 35 is added in scheme two and divides, reduces reduction
The dosage of titanium；Each component is taken according to above two proportion by weight, bonding agent wet-mixing is added, mixed-powder is uniformly made, will mixed
Powder extrusion is closed on core wire, welding rod one and welding rod two is made through high temperature drying；Detection discovery is carried out to welding rod one and welding rod two,
The production is simple and convenient for two kinds of welding rods, and coating is not susceptible to crackle when drying, and welding rod is specious, high-quality, coating and core wire
Switching performance is good, and the striking ability of welding rod is suitable, and slag is less, and de- slag is all easier to, but adds titanium white relative to welding rod one
The welding rod two of powder splashes larger, and the easy hot tearing of weld seam, mechanical performance is poor, frangibility when clod wash, wherein the tension of welding base metal is strong
Degree is 270N/mm2, the weld seam tensile strength after being welded after testing by welding rod one is 273N/mm2, welded by welding rod two
Weld seam tensile strength afterwards is 245N/mm2, found by detection, it is anti-that the welding rod made of scheme two welds the weld seam to be formed
Tensile strength reaches the 90.7% of base material tensile strength, and the welding rod made of the technical program welds the weld seam tensile strength formed and omits
Higher than the tensile strength of base material, it can be seen that, the weld seam tensile strength after the welding of welding rod made of this programme is higher, and scheme two contains
Some raw material titanium dioxides are expensive, and the cost of welding rod two is apparently higher than welding rod one, reduce economic interests.
Second group
Scheme one: 50 parts of titanium of reduction；9 parts of manganese iron；2.5 parts of carclazyte；1 part of wood powder；2 parts of cellulose；6 parts of mica；White clay 10
Part；2.5 parts of clay；10 parts of marble；7 parts of feldspar；
Scheme two: 50 parts of titanium of reduction；9 parts of manganese iron；2.5 parts of carclazyte；1 part of wood powder；2 parts of cellulose；6 parts of mica；White clay 10
Part；2.5 parts of clay；10 parts of fluorite；7 parts of feldspar；
Marble main component be calcium carbonate, the main component of fluorite is calcirm-fluoride, make coating when both effect it is equal
For desulfurization and slag making gas making, scheme two replaces marble with fluorite, each component is taken according to above two proportion by weight, through being added
Mixed-powder is uniformly made in bonding agent wet-mixing, and by mixed-powder extrusion on core wire, welding rod one and welding rod is made through high temperature drying
Two；Detection discovery carried out to welding rod one and welding rod two, the production is simple and convenient for two kinds of welding rods, and coating is not susceptible to split when drying
Line, welding rod is specious, high-quality, and coating is good with core wire switching performance, and de- slag is all easier to；Relative to welding rod one, welding rod two
The fluorite of addition is lower than marble fusing point, and the electrode coating fusing point of production is lower, and slag is diluter, and de- slag ratio welding rod one more holds
Easily, gas in weld metal easily escapes, but welding rod two is poor relative to the stabilising arc ability of welding rod one, and AC welding is difficult, and easily with
Hydrogen, which combines, generates hydrogen fluoride, and hydrogen fluoride is volatile and toxic, and when use need to reinforce safeguard protection, but fluorite itself is nontoxic；Wherein,
The tensile strength of welding base metal is 300N/mm2, the weld seam tensile strength after being welded after testing by welding rod one is 297N/
mm2, the weld seam tensile strength after being welded by welding rod two is 267N/mm2, found by detection, the welding rod made of scheme two
The weld seam tensile strength that welding is formed reaches the 89% of base material tensile strength, and made of the technical program welding rod, which welds, to be formed
Weld seam tensile strength reaches the 99% of base material tensile strength, it can be seen that, the weld seam tension after the welding of welding rod made of this programme
Intensity is higher, and the raw material fluorite price that scheme two contains is more expensive, comprehensively considers, and technical solution of the present invention is made using marble
