Q:Can A102 welding rod weld 316L?: 316L belongs to ultra low carbon austenitic stainless steel, and if using A102, weld metal will reduce the ability to resist intergranular corrosion, so in the relatively high requirements of equipment, as far as possible using A022 welding rod.

Q:One millimeter thick iron direct current welding machine welding 3.2 electrode, need much current?: It will break a bit! It is recommended that you switch to CO2 shielded welding or use resistance welding (designed to allow).

Q:How to calculate the amount of electrode used in pipe welding?: The number of welds can be multiplied by the amount of each opening. The dosage of the cut can be calculated by the quota method or the volume method. Generally, a ton of steel has an average number of electrodes.Carbon steel, stainless steel or alloy steel products are joined together with other products by welding electrodes when they are in production or construction. The seam of the welding rod between the product and the product is called the welding seam. Also called weld seam.

Q:How many kinds of welding rod are there? What's the name? What is the use?: There are many kinds, not less than 100 kinds, welding plastic, cast iron, ordinary steel, alloy steel, stainless steel, etc.

Q:How long is the effective period of welding rod?: If the stock period exceeds the prescribed time limit, the electrode, flux and flux cored wire must be re examined before the relevant functional departments can be issued and used. complexTest principle to check whether the welding material may affect the quality defects, generally limited to appearance and process performance test, but there are doubts on the performance of welding materials, can increase the necessary inspection item.The prescribed time limit may be determined by the following method from the date of production:A) the period of recommendation for welding materials, quality certificates or manuals;B) a low hydrogen type welding material for acid welding materials and moisture resistant packages, sealed for two years;C) graphite type welding materials and other welding materials for one year.

Q:Is the electrode electrically conductive?: An electrode is a conductor. The electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire. When welding, the welding core has two functions: one is the conduction of the welding current, arc energy converted into heat, two cores melting as the formation of the weld filler metal and liquid base metal fusion.Electrode welding, welding core metal part of the weld metal. The chemical composition of cores, directly affect the quality of the welding seam. Therefore, the steel wire used as the core of the electrode has its brand and its composition separately. If used for automatic submerged arc welding, electroslag welding, gas welding, gas welding and other welding methods for the filler metal, known as the wire.The coating layer is coated on the surface of coating is the core. In the course of welding, the coating is decomposed and melted to form gas and slag, which play a role in mechanical protection, metallurgical treatment and technological performance improvement. Composition of coating material: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.). For example, a light electrode without a coating is not easy to ignite the arc. Even if ignited, it can not burn steadily. In the electrode coating, usually contains potassium, sodium, calcium and other ionization potential of low substances, which can improve the stability of the arc, to ensure that the welding process continues.

Q:What is the cause of partial magnetic blow?: The magnetic lines of force around the arc may be evenly distributed;2) adjust the dip angle of the welding rod properly and tilt the electrode towards the blowing direction;3) the method of subsection retreat welding and short arc welding can effectively overcome the magnetic deviation blow;4) AC welding instead of direct current welding. When alternating current welding is used, the induced current is induced by the changing magnetic field in the conductor, and the magnetic field produced by the induced current weakens the magnetic field caused by welding current, thus controlling the magnetic bias blow;5) place a ferromagnetic material that produces a symmetrical magnetic field, so that the ferromagnetic material around the arc is uniformly distributed;6) reduce the residual magnetism on the weldment. The residual magnetism on the weldment is mainly caused by the orderly arrangement of atoms and domains. In order to reduce or prevent the magnetic deviation of the magnetic domain arrangement of the weldment, the part of the residual magnetism on the weldment can be locally heated, and the heating temperature is 250~300 degrees centigrade. After production, the demagnetizing effect is good. Moreover, in the residual magnetic field of the weldment, the applied magnet balances the magnetic field.7) reverse demagnetization. That is, a magnetic field is produced by the welding piece to counteract the residual magnetism on the weldment so as to overcome and eliminate the influence of the magnetic deviation blow on the welding arc.

Q:What are the technological parameters of E5015 welding rod?: Answer: is the ordinary alkaline welding rod, welding, welding rod connected to the positive electrode, the workpiece connected to the negative electrode. Different electrode diameter, welding current is not the same. This is marked on the package of the electrode!

Q:Air conditioning copper pipe welding problems, how to weld well, and what electrode to use?: Is the use of copper wire, welding, brazing is the longest, with the copper wire, with borax flux do. The gas heating tube to cherry red, under the solder wire, a coating will flow into, good welding.

Q:Who knows what welding electrode is?: 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
