Abstract
The invention provides a welding electrode which comprises a welding wire and a coating. The coating comprises, by weight, the components of 34%-37% of nitrocellulose, 36%-38% of calcium carbonate, 7%-9% of ferromanganese, 17%-19% of sodium ferrite and 1%-3% of sodium chloride. The welding electrode has the advantages that nickel which is harmful to human bodies and fluorine which harms the atmospheric ozone layer are not contained, namely cancerogenic substances and harmful gas of fluoride slag are not generated during a welding process, non-toxic performance is achieved, dust is low, electricity is saved, harm and influence on ecological environment and the life of an electrowelding technician are avoided, all kinds of carbon steel, alloy steel and casting pieces can be directly subjected to cold welding without preheating, compared with a similar welding rod, anti-cracking performance is good, super toughness and super plasticity are achieved, different metal materials such as ferrite, pearlite, and austenite with different qualities can be subjected to overall combined welding, and welding seams are firm and solid.
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 carbonyl nickel 1. producing in welding can make the BaP in human body continue to increase or human DNA is undergone mutation, therefore electric welding skilled worker uses such welding rod can be carcinogenic for a long time, serious harm healthy; The pernicious gas of the fluoride slag 2. producing in welding, has destroyed atmospheric ozone layer, harm environmental quality and the ecological balance; 3. in welding, need parts to be welded to carry out preheating, not only increased operation, promoted production cost, and affected welding efficiency; 4. in welding, the metal material to facial differences such as inhomogeneous ferrite, pearlite, austenites, is difficult to realize and closes weldering.
Summary of the invention
For above deficiency, the invention provides a kind of welding rod.
Technical scheme of the present invention: a kind of welding rod, comprise welding wire and coating, described coating is comprised 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%.
Especially, described coating is comprised 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 technique effect:
(1) product of the present invention is not containing the nickel of harmful to human and the fluorine of destruction atmospheric ozone layer, it is the pernicious gas that does not produce carcinogen and fluoride slag in welding, nontoxic, low dirt, power saving,, nothing impact harmless on ecological environment and electric welding skilled worker's life security;
(2) not after the heat directly various carbon steels of cold welding, steel alloy and foundry goods; Good with the similar welding rod cracking resistance of comparing, there is super toughness and superplasticity;
(3) to the metal material of the facial differences such as inhomogeneous ferrite, pearlite, austenite, can implement integral body and close weldering, weld seam is solid firmly;
(4) can AC and DC dual-purpose, voltage stabilization, splashes little, medicinal powder easily at the beginning of, de-slag is easy;
(5) slag fluidity is moderate, and convenient operation person faces upward, stands, puts down, the all-position welding such as horizontal;
(6) weld bond fusion is 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 specification requirement of various high-quality welding and repair welding;
(7) to the weldment that corroded by Korrosionsmedium, do not need through chemical treatment, directly cold welding;
(8) weld bond can bear tension, the anti-pressure ability of 120khf/m ㎡, has surpassed the index of the highest 100khf/m ㎡ in the current world of Belgian production, for the manufacture of the special process such as submarine, nuclear submarine provides extremely desirable welding rod;
(9) product price is cheap, and price is only 1/2nd of casting 308 welding rod, and in welding than conventional welding rod power saving 15 ~ 25%, greatly reduce user's welding production cost;
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 and hand over weldering, needs the good and tension compressive resistance of processing characteristics to be greater than the highly difficult welding that waits special occasions and the technique link of 100khf/m ㎡ without temper.For example: be subject to the naval vessel shell of the long-term etch of sodium chloride seawater, can not do the direct cold welding of any chemical treatment; The wearing and tearing such as the big-and-middle-sized roll of the value several ten thousand of various steel rolling mills and even millions of units and the driving crank of power industry or fracture; Take the various foundry goods that HT, QT, KT, ZG etc. are material, as the casting flaws such as pore that lathe, radiator etc. occurred, sand holes all can be carried out repair welding redemption; Aircraft lands the safety of wheel shaft and installs; The teeth that the excavates soil welding that fractures; The gear ring of large-scale transmission worm gear machine is connected with liner; Stand the welding such as various submarines of deep water weight; It is that riveting is made that the tradition of various space shuttle devices links technique, as Chinese its first man made earth satellite,, because pressure reduction sudden change is blasted, at diameter, be only on the area of a circle more than 1 meter, just to have rivet up to ten thousand individual when preventing soar into space, to processing and manufacturing, brought great trouble.This high energy welding rod property on probation is strong, is not substantially subject to the restriction of any condition, and low price, therefore, along with the continuous generation exploitation of kind series, and will be widely used in addition.
The specific embodiment
embodiment 1:
A welding rod, comprises welding wire and coating, and described coating is comprised of the component of following weight percentage: cellulose nitrate 34%, calcium carbonate 36%, ferromanganese 9%, sodium ferrite 18%, sodium chloride 3%.
embodiment 2:
