Q:Welding Q345C steel plate with ordinary electrode?
Yes. Ordinary structural steel electrode can be used, but attention should be paid to the strength of the steel. Q345 steel corresponding welding rod should be 500MPa class, that is, E50 * * * or J50 * grade electrodes, such as E5003 (or J502), E5015 (J502) and so on.
Q:What kind of welding rod or welding wire for welding Q245R steel?
Q245R is generally used in boiler or pressure vessel, if it is a large diameter cylinder welding body in wall thickness below 8mm recommended the use of arc welding J507 welding rod, double welding, carbon arc gouging back, to obtain inspection qualified; wall thickness is thick, can be used for submerged arc welding. The use of H08MnA wire HJ431 welding flux;If the smaller diameter of the cylinder, the inner wall of the can go in welding, open V groove on the weld position, the use of manual TIG welding primer (ER50-6 wire), welding electrode (J507 electrode) filling cover, if the wall thickness is more than 10mm, you can also consider the use of submerged arc welding (filling cover H08MnA HJ431 solder wire);If the welding weld is non pressure parts, you can use the CO2 gas shielded arc welding, using 1.2 or 1.6 ER50-6 diameter wire welding, weld spatter if you need better or less, recommend the use of Ar:CO2 mixed gas 8:2 welding.
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
Arc welding is a sudden disconnection, producing high voltage arc, burning welding rod
Q:What is the difference between electrode type and brand?
J422 acid electrode type GB E4303Structural steel welding rod, weld metal tensile strength of not less than 420Mpa, titanium oxide calcium type leather, AC and DC dual-use, mainly for welding low carbon steel and low strength alloy steel, such as 09Mn2 and so onJ427 basic electrode type GB E4315Structural steel welding rod, weld metal tensile strength of not less than 420Mpa, low sodium hydrogen type leather, DC reverse welding, mainly used for welding of important low carbon steel and low alloy steel, such as 09MnSi, etc.
Q:How much is the angle between the horizontal fillet welding, welding and butt welding?
A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.
Q:What does the electrode strip E7108 stand for?
According to the national standards GB/T 5117 and GB/T 5118, the electrode is defined as this:The first letter, "E" - represents an electrode. (what electrodes are indicated by E)?Second, third digit "71" - represents the minimum tensile strength of deposited metal material. (71 MPa)Fourth digit "0" - indicating the applicable welding position. (0 means for all positions, any one will do.)Fifth digit "8" - indicating the type of electrode coating and the type of current used. (8 iron powder, low hydrogen content skin, DC reverse connection)The other figures in the back are the chemical composition, material type, and so on. Generally speaking, the first five will be enough.
Q:What kind of welding rod does Q345A board use?
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 kind of welding rod does aluminum alloy use?
Specific to see what aluminum alloy, different aluminum alloy may use different welding rod.Turn left and turn right |Turn left and turn right |Turn left and turn right |Aluminum and Aluminum Alloy wire can be used for welding processing spool or longitudinal incision of MIG or TIG, according to its composition can be divided into pure aluminum, aluminum silicon and aluminum magnesium wire into a disc through certain processing methods (coils) or rod (bar) supply, widely used in construction, decoration and equipment, metallurgy and spinning apparatus, pipelines, ships, drilling equipment, train, car, storage tanks and pressure vessels welding processing industry and other industries. Precautions for product use:1, the package after the warranty period you can directly connect the welding, welding without any pretreatment. The product can be stored for more than two years under the condition of packing and sealed. After packing, it can be guaranteed for three months in the normal atmospheric environment;2, the product should be placed on ventilation, dry and with acid and alkali, oil and other local storage medium isolation;3, the product should avoid bumping and damp during transportation, in order to avoid damaging the wire tray and affecting the quality of wire;4, after the wire is removed and packed, it is recommended to apply proper dust cover over the welding wire;5. The wire surface cleaning is recommended before welding;6, welding process of the arc will stimulate your eyes, please pay attention to protection.
Q: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..
Q:H13 what kind of welding rod is used for steel welding?
H13 is because the hot die die, as far as possible without welding, such as welding and molding after then try to use the stainless steel welding rod or wire, if you need to have the strength of welding, preheating in the best welding preheating temperature between 500-600 degrees is appropriate, the good after welding with some insulation material covering. Such as asbestos, the slow cooling speed, reduce welding stress.Avoid soldering prior to heat treatment.
