Embodiment 1

[0009] Embodiment 1: Take the following components according to the mass fraction: 15 parts of attapulgite raw ore, 10 parts of quartz sand, 20 parts of dolomite, 50 parts of magnesite, and 5 parts of iron powder; the above-mentioned components are put into a mixer and stirred evenly to mix Powder, press-coat the mixed powder on the welding core, and dry at high temperature to form the electrode coating.

Embodiment 2

[0010] Example 2: Take the following components according to the mass fraction: 40 parts of attapulgite raw ore, 5 parts of quartz sand, 17.5 parts of dolomite, 34.5 parts of magnesite, and 3 parts of iron powder; the above-mentioned components are put into a mixer and stirred evenly to obtain a mixture Powder, press-coat the mixed powder on the welding core, and dry it at high temperature to form the electrode coating.

Embodiment 3

[0011] Embodiment 3: Take the following components according to the mass fraction: 65 parts of attapulgite raw ore, 15 parts of dolomite, 19 parts of magnesite, 1 part of iron powder; the above-mentioned components are put into a mixer and stirred evenly to obtain a mixed powder, which is mixed The powder is press-coated on the welding core and dried at high temperature to form the electrode coating.

[0012] The welding process performance test was carried out by using the welding electrodes obtained in Examples 1-3. The experimental results showed that the arc was stable during welding, the spatter particles were fine, the weld shape was smooth and beautiful, and the slag was easy to remove after welding. The slag removal rate was greater than 95%. Dust rate is less than 0.23g / min, dust generation is less than 11g / kg, safe and non-toxic.

Abstract

The invention discloses a welding electrode coating. The welding electrode coating comprises components of, by mass, 15-65 parts of attapulgite of medium-low grades, 0-10 parts of quartz sand, 15-20 parts of dolomite, 19-50 parts of magnesia and 1-5 parts of iron powder. According to the welding electrode coating, used attapulgite raw ore is rich in reserve and low in price and provides a stable raw material source for coating welding, and welding electrodes obtained on the basis are low in cost, stable in arc and small in spattering particle during welding, prone to slag removal after welding, smooth and attractive in formed weld joint, low in welding dust generating rate, safe and non-toxic, good in economic and environment benefit and broad in application prospect.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary materials, in particular to a welding electrode coating. Background technique [0002] As an important material processing technology, welding is widely used in petrochemical, electric power, aerospace, power engineering, microelectronics technology, bridges, ships and various metal structures and other industrial sectors. For every ton of steel used in modern buildings, bridges, shipbuilding and other industries, about 300 kilograms of welding materials are consumed. In general engineering construction, 30% of steel materials need to be welded. Growth; According to the statistics of the national industrial sector, the annual demand for welding rods in my country is 15 million tons, but the actual production is less than 1 million tons. Therefore, the welding rod market has a large demand space, and the demand for electrode coatings increases accordingly. [0003] For the raw materials o...
