Abstract
The invention discloses an anticorrosion welding electrode comprising a core and a coating. The outer wall of the core is covered with the coating. The core is made of SNi6062. The anticorrosion welding electrode is characterized in that the coating accounts for 40-47% of the total weight of the welding electrode, and based on the total weight of the coating, the coating is made with, by weight, 39-51% of rutile, 2.5-7% of titanium dioxide, 23-32% of potassium feldspar, 3-11% of cryolite, 2-6% of mica, 2.5-7% of zircon sand, 1-1.5% of sodium carbonate, 7-10% of manganese, 1.5-6% of ferrotitanium, 2-3.5% of ferrovanadium. The surface of a workpiece welded with the anticorrosion welding electrode has high resistant against non-oxidizing acids; the anticorrosion welding electrode is applicable to factories.
Description
Technical field
The present invention relates to the welding rod using in a kind of factory.
Background technology
At present, domestic tower, groove, pipeline and the storage-transport vessel etc. of manufacturing out various strong acid, these equipment and structure all require material to have the well performance of resistance to various acid corrosions.Stainless steel relies in steel and contains enough chromium, forms very thin fine and close oxide-film on the surface of steel, prevents further oxidation or corrosion.Acid can be divided into oxidizing acid and reductive acid by its oxidisability power.Oxidizing acid, can resist by strengthening this film, and reductive acid must destroy this film, causes the corrosion of steel.Therefore the weld seam after general stainless steel electrode welding can oxidative resistance acid, and to non-oxidizing acid, its corrosion resistance is just poor.Therefore can either oxidative resistance acid in the urgent need to one, welding material that again can good resistance to non-oxidizing acid.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of corrosion-resistant welding rod of research and design, in order to solve existing welding rod postwelding surface of the work to the poor shortcoming of non-oxidizing acid corrosion resistance.The technological means that the present invention adopts is as follows:
A kind of corrosion-resistant welding rod, comprises core wire and coating, and coating is coated on the outer wall of core wire, and described core wire is SNi6062; It is characterized in that: described coating accounts for 40～47% of welding rod gross weight, described coating, take the gross weight of coating as benchmark, counts by weight percentage, and described coating component comprises:
Rutile: 39-51%;
Titanium dioxide: 2.5-7%;
Potassic feldspar: 23-32%;
Ice crystal: 3-11%;
Mica: 2-6%;
Zircon sand: 2.5-7%;
Soda ash: 1-1.5%;
Manganese metal: 7-10%;
Ferrotianium: 1.5-6%;
Vanadium iron: 2-3.5%.
Be 5.60～5.90mm as the external diameter of preferred described welding rod.
Compared with the prior art, the present invention has the following advantages:
1, postwelding has excellent welding technological properties;
2, the stable mechanical performance of welding deposited metal;
3, higher to the corrosion resistance of non-oxidizing acid;
The advantages such as the present invention has can realize suitability for industrialized production, and cost performance is high, and postwelding mechanical performance is superior, it puts goods on the market and will produce Social benefit and economic benefit significantly.
The specific embodiment
Embodiment 1, a kind of corrosion-resistant welding rod, comprises core wire and coating, and coating is coated on the outer wall of core wire, and described core wire is SNi6062; It is characterized in that: described coating accounts for 40～47% of welding rod gross weight, described coating, take the gross weight of coating as benchmark, counts by weight percentage, and described coating component comprises:
Rutile: 39-51%;
Titanium dioxide: 2.5-7%;
Potassic feldspar: 23-32%;
Ice crystal: 3-11%;
Mica: 2-6%;
Zircon sand: 2.5-7%;
Soda ash: 1-1.5%;
Manganese metal: 7-10%;
Ferrotianium: 1.5-6%;
Vanadium iron: 2-3.5%.
The external diameter of described welding rod is 5.60～5.90mm.
Welding rod of the present invention belongs to Gao Ge, nickel, molybdenum and Ultra-low carbon wlding, there is excellent welding technological properties, and the stable mechanical performance of its deposited metal, weld seam has good corrosion resistance, compared with other austenite stainless steel-made welding rods, there is outstanding anti-spot corrosion, the advantage of the corrosion resistance of anti-crevice corrosion, intercrystalline corrosion, stress corrosion cracking and anti-general corrosion.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
