Description
Technical field
The present invention relates to a kind of welding rod.
Background technology
Traditional welding rod in use has following shortcomings and deficiencies: the Nickel tetracarbonyl. 1. produced in welding can make the benzopyrene in human body persistently increase or make human DNA undergo mutation, and therefore such welding rod of electric welding skilled worker life-time service can be carcinogenic, and serious harm is healthy；The harmful gas of the fluoride slag 2. produced in welding, destroys atmospheric ozone layer, harm environmental quality and ecological balance；3. need parts to be welded are preheated in welding, not only increase operation, improve production cost, and have impact on welding efficiency；4. the metal material in welding, to facial differences such as inhomogeneous ferrite, pearlite, austenites, it is difficult to realize closing weldering.
Summary of the invention
For above not enough, the present invention provides a kind of welding rod.
Technical scheme: a kind of welding rod, including welding wire and coating, described coating is made up of the component of following weight percentage: cellulose nitrate 34-37%, calcium carbonate 36-38%, ferromanganese 7-9%, sodium ferrite 17-19%, sodium chloride 1-3%.
Particularly, described coating is made up of the component of following weight percentage: cellulose nitrate 35.75%, calcium carbonate 37.15%, ferromanganese 8.04%, sodium ferrite 17.17%, sodium chloride 1.89%.
The present invention has following technical effect that
(1) the product of the present invention nickel without harmful to human and destroy the fluorine of atmospheric ozone layer, does not i.e. produce carcinogen and the harmful gas of fluoride slag in welding, dirt nontoxic, low, power saving are harmless, without impact on the life security of ecological environment and electric welding skilled worker；
(2) can the directly various carbon steel of cold welding, steel alloy and foundry goods after heat；Cracking resistance is good compared with similar welding rod, has ultra-tough and superplasticity；
(3) metal material to facial differences such as inhomogeneous ferrite, pearlite, austenites can implement overall conjunction weldering, and weld seam is solid firmly；
(4) can AC and DC dual-purpose, voltage stabilization, splash little, medicated powder easily at the beginning of, de-slag is easy；
(5) slag fluidity is moderate, it is simple to operator faces upward, stands, puts down, the all-position welding such as horizontal；
(6) weld bond merges functional, and appearance of weld is attractive in appearance, and color and luster and mother metal are without significant difference, and after cold welding, hardness is moderate, and internal stress is evenly distributed, and does not need to do temper, and processability is good, can meet the technology requirement of various high-quality welding and repair welding；
(7) to the weldment corroded by Korrosionsmedium, do not need chemically treated, can direct cold welding；
(8) weld bond can bear the tension of 120khf/m, anti-pressure ability, has exceeded the index of the highest 100khf/m in the current world of Belgian production, and the manufacture for the special process such as submarine, nuclear submarine provides highly desirable welding rod；
(9) product price is cheap, and price is only 1/2nd of casting 308 welding rod, and than conventional welding rod power saving 15 ~ 25% in welding, greatly reduces the welding production cost of user.
Welding rod product of the present invention can extremely be widely used in temperature difference great disparity in defence and military, space flight, aviation, shipbuilding, oil, chemical industry, metallurgy, cast steel, boiler, narrow-necked earthen jar body, mine, digging, pressure vessel, metal structure and all industrial circles, Korrosionsmedium etch, non-homogeneity material hand over weldering, needs processing characteristics good without temper and the highly difficult welding waiting special occasions more than 100khf/m of the tension compressive resistance and technique link.Such as: by the naval vessel shell of the long-term etch of sodium chloride sea water, the direct cold welding of any chemical treatment can not be done；Abrasion or the fractures such as the value several ten thousand of various steel rolling mills or even the driving crank of the big-and-middle-sized roll of millions of unit and power industry；Various foundry goods with HT, QT, KT, ZG etc. as material, the casting flaw such as the pore occurred such as lathe, radiator etc., sand holes all can carry out repair welding redemption；Aircraft land wheel shaft safety install；The teeth excavating soil fractures welding；The gear ring of large-scale transmission worm gear machine and the connection of liner；The various submarines etc. standing deep water weight weld；It is that riveting is made that the tradition of various space shuttle devices links technique, its first man made earth satellite such as China, explode because pressure reduction sudden change during for preventing soar into space, on a diameter of area of a circle more than 1 meter, only just have up to ten thousand of rivet, bring to processing and manufacturing and bother greatly.This high energy trying out property of welding rod is strong, is not substantially affected by the restriction of any condition, in addition low price, therefore, constantly produces exploitation along with kind series, and will be widely used.
Detailed description of the invention
Embodiment 1:
A kind of welding rod, including welding wire and coating, described coating is made up of the component of following weight percentage: cellulose nitrate 34%, calcium carbonate 36%, ferromanganese 9%, sodium ferrite 18%, sodium chloride 3%.
Embodiment 2:
A kind of welding rod, including welding wire and coating, described coating is made up of the component of following weight percentage: cellulose nitrate 37%, calcium carbonate 38%, ferromanganese 7%, sodium ferrite 17%, sodium chloride 1%.
Embodiment 3:
