Who knows what welding electrode is?
Composition and function of welding electrode:One electrode. By core (metal core) and coating composition1. cores: metal cored electrode is coated with coating. Manual welding, welding electrode is not only.Filler metal.2. coating: pressure on the surface of the coating layer on the electrode. It is composed of a variety of ores, iron alloys, cellulose and binders.Two. Role of welding rodThe main function of the 1. cores:Act as an electrode to conduct current and to ignite an arc.Melt as filler metal and weld together with molten parent metal. In order to guarantee the quality of welding seam, the chemical composition of weld metal is more strict. Therefore, the core is specially smelting, low carbon and silicon content, sulfur and phosphorus content is extremely low.2., the main role of the drug skin:Mechanical protection: use the gas released from the melting of the crust and form the slag to isolate the air to prevent harmful gases from invading the molten metal.Metallurgical treatment: place harmful impurities (such as oxygen, hydrogen, sulfur and phosphorus) and add useful alloy elements, so that the welding seam can meet the required chemical composition and mechanical requirements.To improve welding performance: to make the arc combustion stable, less spatter, good weld formation, easy to remove slag, etc..
Welding rod is the main raw material of welding for national defense, machinery, chemical, metallurgy, mining, shipbuilding, automobiles, tractors, agricultural machinery, construction, repair and other industries. Titanium dioxide is one of the main raw materials of welding rod industry, and the three kinds of welding electrodes, such as titanium, titanium, calcium and ilmenite, should be made of titanium dioxide, which accounts for more than 70% of the total electrode output. Therefore, the annual needs are large and the quality requirements are high.Titanium dioxide is the main components of the welding surface of the medicine in the skin, it is the good welding slagging agent and deoxidizer, diluent, adhesive and stabilizer. The welding slag made by the utility model has the advantages of low melting point, small viscosity, alternating current and direct current, and the utility model has the advantages of quick arc operation, stable arc, easy slag removal, good welding seam and good mechanical performance. Titanium dioxide deoxidization ability in medicine in the skin is also very good, in the welding process can protect the molten metal to prevent the oxygen in air or nitrogen penetrated weld decreased weld strength and plasticity, also the formation of titanium nitride, titanium and nitrogen stable, quickly into the slag, thereby eliminating the influence of nitrogen on weld. At the same time, titanium dioxide has a strong adhesion, in the electrode manufacturing process can reduce the amount of water glass, so that the surface of finished products smooth, easy welding point arc
