Abstract
The present invention relates to a stainless steel welding rod with air hole resistance and high efficiency. The welding rod is composed of a stainless steel core and a coating, wherein the coating is prepared from the components by the following percentage: 76 to 85 of conventional powder material, 9 to 14 of refractory powder, 5 to 8 of sodium fluorosilicate and 1 to 2 of aluminum silver powder. The present invention has the advantages of fast welding, no air hole in welding, no redness and no falling off of the coating, high utilization rate, favorable moisture resistance, etc.
Description
The present invention is a kind of stainless steel welding electrode.
At present, in use because the composition of its coating and the irrationality of set of dispense ratio cause it in welding process, there is following defective in stainless steel welding electrode: the one, and weld seam has pore.The 2nd, work efficiency is low, can only weld with less welding current, stipulates it is 80-110A as the welding current of the thick stainless steel welding electrode of φ 3.2mm by industry.Otherwise, because of the conference of welding rod steel core resistance produces higher temperature, make the coating can be rubescent after being soldered to half, even take off and split, thereby influence welding quality.
The objective of the invention is to overcome above-mentioned defective, a kind of non-air-hole high-efficient stainless welding rod is provided.
The object of the present invention is achieved like this: be made up of stainless steel core and coating, wherein, coating component and constituent content percentage are: refractory powder 9-14, prodan 5-8, aluminium silver powder 1-2, synthetic rutile 38-40, titanium dioxide 4-6, crome metal 7-10, manganese metal 4, chrome green 6-8, marble 2, feldspar 6, fluorite 5, synthetic mica 2.5, ferrotianium 1 and alkali face 0.5.
The effect of above-mentioned refractory powder is: can make welding rod produce baking temperature and bring up to more than 430 ℃ by conventional 350 ℃, thereby remove the crystallization water in the coating more up hill and dale, the crystallization water is the reason that causes welding pore phenomenon; Simultaneously, it is rubescent and take off and split phenomenon to overcome coating, that is to say the mechanical strength that has improved coating, thereby helps improving work efficiency greatly; Can also improve the moisture resistivity of welding rod.Prodan also has anti-pore, and anti-coating is rubescent and come off, and the effect that improves work efficiency.Aluminium silver powder then has the deoxidation intensity when strengthening welding and improves the effect of taking off slag, being coated with the pressure performance.All the other components are conventional materials.
Through a large amount of welding procedure contrast tests, the present invention has stainless steel welding electrode now with domestic how tame manufacturer and compares, and following advantage is arranged:
One, the welding rod anti-moisture performance is good, and manufacturing process does not have specific (special) requirements, is produced by " hydraulic oil pump ".
Its two, welding current is big, improves 35% approximately than routine.With the thick stainless steel welding electrode of φ 3.2mm is example, and conventional welding current is 80-110A, and the present invention then is 80-150A.Therefore, welder's arc manipulation is speeded up, improve the welding work efficiency more than 40%.
Its three, the all-position welding processing quality is good, physics and chemistry detects test and all reaches standard GB 983-85 " stainless steel welding electrode ", and electrode coating not rubescent, take off and split, the weld seam pore-free.
Its four, remove bare terminal end, the utilization rate of welding rod reaches 100%.
The invention will be further described below in conjunction with embodiment:
The present invention is made up of stainless steel core and coating, and coating comprises refractory powder, prodan, aluminium silver powder, synthetic rutile, titanium dioxide, crome metal, manganese metal, chrome green, marble, feldspar, fluorite, synthetic mica, ferrotianium and alkali face again.
Above-mentioned coating component percentage composition is: refractory powder 9-14, prodan 5-8, aluminium silver powder 1-2, synthetic rutile 38-40, titanium dioxide 4-6, crome metal 7-10, manganese metal 4, chrome green 6-8, marble 2, feldspar 6, fluorite 5, synthetic mica 2.5, ferrotianium 1, alkali face 0.5.
Product manufacture of the present invention, except that the coating baking temperature is chosen as 430 ℃ condition, all the other same prior aries.
The constituent content and the effect thereof of coating among the present invention are described with form below.
| Experimental program constituent content percentage component title | One | Two | Three | Four |
| Refractory powder | 12 | 9 | 14 | 11.5 |
| Prodan | 6 | 8 | 5 | 6.5 |

| Ferrotianium | 1 | 1 | 1 | 1 |
| The alkali face | 0.5 | 0.5 | 0.5 | 0.5 |
| Add up to | 100 | 100 | 100 | 100 |
Go to implement according to constituent content percentage data given in the above table, four kinds of scheme effects all can, wherein best with scheme one effect.The stainless steel welding electrode of being produced all meets country " GB983-85 " " stainless steel welding electrode " performance indications, and, use its welding, all can guarantee welding quality, coating is not rubescent, come off, pore-free, work efficiency is also fast.
