Q: How much current does 4 of welding rod use?: 4 of the 422 welding electrode, welding with 200, with 140 to 160, 170 to 180 horizontal welding, welding horizontal welding with elevation of almost 140 to 150507 flat plate overhead by 180 to 200, 140 to 160 vertical welding, horizontal welding of 160 to 170, with the elevation of welding horizontal welding almost flat overhead welding 130 140, of course, with the personal habits and thickness have relations.

Q: How are the electrodes made up?: Answer: welding rod is coated with the skin of the power supply arc welding melting electrode. It is composed of two parts covering and core wire. (L) cores. 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 energy; two welding core melting filler fused with the parent metal weld formation. The special steel wire used for welding can be divided into three categories: carbon structural steel, steel wire, alloy structural steel wire and stainless steel wire. (2) medicine skin. The pressure on the surface of electrode coating called coating. A coating of various minerals, such as minerals, is coated on the outside of the electrode to stabilize the arc and improve the quality of the weld. Some reducing agents should be added into the coating to restore the oxide to ensure the quality of the weld. Because of the high temperature of the arc, some of the alloying elements contained in the weld metal are burned (oxidized or nitrided), which reduces the mechanical properties of the weld. By adding ferrous alloy or pure alloy element to the electrode coating, it can be transferred to the weld metal with the melting of the coating, so as to compensate for the burning of the alloy elements and to improve the mechanical properties of the weld metal. It can improve the welding process performance, make the arc stable combustion, less spatter, good weld formation, easy slag removal and high deposition efficiency. In short, the role of the drug skin is to ensure that the weld metal to obtain the required chemical composition and mechanical properties, and make the welding rod has good welding process performance.

Q: Can ordinary 422 electrode welding pig iron?: Not welding, easy to fall off after welding, resulting in more defects more defects. Can use cast iron welding rod Z308, the worst to use A302.

Q: What is the difference between tin strip and electrode?: Tin is made of tin and has a low melting point. It is commonly used for the connection of small items such as circuit connections of integrated circuits. The principle is that the crystal is melted by heating.The outer electrode is a mixture of phosphorus and other combustible material, the middle is iron, high melting point, used to connect large metal objects, the work is a glare, hurt the eyes, the working principle is the crystal of heat melting and high pressure arc discharge.The electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece. Consists of two parts covering and core wire. Depending on the melting of the crust and filling the metal into the weld, it becomes the main component of the weld metal, which is called a welding rod.Tin is a kind of product in solder, tin can be divided into a tin lead and lead-free solder two, are used for welding circuit board. Pure tin manufacturing, wettability, good fluidity, easy to Shangxi. Bright spot, full, no weld and other undesirable phenomena. Add adequate antioxidant elements, strong antioxidant capacity. Pure tin manufacturing, tin slag less, reducing unnecessary waste.

Q: What welding rod does 16MnDR use?: 1 and 16MnDR belong to low temperature steel.2, welding rod selection grade: J507NiTiB, J507GR, J507RH, J506R, J506RH, more can.

Q: What kind of welding rod is Mt -12?: MT-12 is J421 (E4313) - type carbon steel welding rod.Carbon steel electrode (its tensile strength of deposited metal is less than or equal to 500MPa or 50kgf/mm2), suitable for welding carbon steel and low strength low alloy steel.The electrode of low hydrogen type, powder type, welding electrode must be baked above 350 DEG C, as far as possible to do with baking with, how much the drying principle, otherwise it will result in welding defects (such as porosity, cracks, slag, clamping process performance deterioration etc.). The cellulose type welding rod should be baked strictly according to the baking temperature stipulated in the instruction. When the temperature is too high, the cellulose in the coating will be burned and the inherent technological property of the welding rod will be destroyed.When using the low hydrogen electrode, the welder shall be in the upper wind position, strengthen the exhaust air, and prevent the welding fume from damaging the body.For the low hydrogen type welding rod, the number of baking can be less than two times as much as possible, so as to prevent the medicine skin from becoming brittle and falling off.

Q: Commonly known as "white steel electrode" what does it mean?: I produce stainless steel electrode, stainless steel wire and all kinds of special welding rod, welding wire

Q: Is the resistance of welding electrode large?I don't know much about welding. I want to know the general resistance of welding electrode. I also want to know the difference between welding and sub arc welding: No, it can be very small!The core of the electrode is made of good conductive material. The solder around the core is a poorly conductive material.Welding is the use of contact resistance between the electrode and the workpiece is larger, so the heat is larger, the solder, cores and workpiece partial melting, achieve the purpose of welding.

Q: Can the Q345A board be welded with 422 electrodes?What kind of welding is best?Thank you!: Q345A (16Mn) is a low carbon structural steel. The electrodes that match the grade strength are the J50- series (E50--)Non important construction can be welded with J502 (E5003) titanium calcium type acid welding rod. The welding rod is good in welding technology and easy to remove slag. The electrode is cheap and suitable for AC welder and DC welding machine. The disadvantage is that the toughness is inferior to the basic electrode.The most important structures can be welded with J506 (E5016) low hydrogen potassium basic electrode. The electrode is suitable for welding of alternating current welding machines with no-load voltage equal to greater than 70V and load rate equal to greater than 60%. And welding of DC welding machine. The electrode contains arc stabilizer, suitable for AC DC welding machine welding.An important structure, such as a rigid larger member, a pressure vessel. Or other structural parts requiring higher welding. Using J507 (E5015) low hydrogen sodium type basic welding rod welding. The electrode does not contain arc stabilizer. Only AX arc welding generator, ZX5 SCR direct current welding machine, ZX7 inverter type DC welding machine welding. ZXG series silicon rectifier welding machine is affected by the fluctuation of input voltage, so it can not be used.

Q: What electrode does Q235 use?: According to the classification of the characteristics of the slag after the electrode is melted, the welding electrode can be divided into an acid welding rod and an alkaline welding rod. The main component of acid electrode coating is acid oxide, such as Q235 low carbon steel. When welding important structural parts, E4315, E4316, E5015 and E5016 should be selected according to different welding conditions.Q235 is a carbon structural steel, which is equivalent to the A3 and C3 steel in the old standard GB700-79, and is used in the Russian TOCT brand. The grade Q represent in yield strength. Normally, the steel is not used directly after heat treatment.
