             produces a deep penetrating weld and works well on dirty,rusted, or painted metals 

E6011 This electrode has the same characteristics of the E6010, but can be used with AC and DC currents. 

E6013 This electrode can be used with AC and DC currents. 

             produces a medium penetrating weld with a superior weld bead appearance. 

E7018 This electrode is known as a low hydrogen electrode and can be used with AC or DC. 

The coating on the electrode has a low moisture content that reduces the introduction of hydrogen into the weld. lectrode can produce welds of ray quality with medium penetration.

Q:Can invert welding machine use acid welding rod?
The kind of welding machine that you said could be used with an acid electrode. He has many functions, which can be shared by AC and DC, with separate DC or AC, of course, the price is different. About 20KG or so, the market is now available from 300-800. Import, brand, public can not be the same, the price varies greatly. The big 315 is now 450-550 between.
Q:What kind of welding rod Z208 is the main material for welding?
The welding rod Z208 belongs to the low carbon steel core, strengthens the graphite coating the cast iron welding rod.Welding rod Z208 welding base material: mainly used for iron parts defects repair, crack resistance is poor.Attention to welding Z208 welding rod:A small thin-walled castings, steel parts of the defect can not be preheated welding, while the general welding needs preheating 400 degrees or so, after welding insulation and cold, then welding may be carried out cutting.For the important casting structure to bear stress and impact, the welding rod should not be adopted.Before welding, the electrode should be baked for about 1 hours at around 150C.
Q:E9015-B9 is a welding rod for which steel is welded
E9015-B9 is the standard of AWS, is we often say that the T91 welding material, welding P91/T91 steel, welding pipe is 9Cr1Mo. There are more heat resistant pipes in the power system now.
Q:Is it possible to use an AC welder for 506 electrodes?
506 belong to basic electrode, welding with DC output welding machine
Q:How do you know it's a white steel electrode?
Each electrode has a number of general Yilingjisanlingji is white steel 422 is carbon electrode 507 is 506 manganese steel electrode coating structure is just the most common can also see the skin color outside the carbon steel electrode is grey white steel is green and white are easy to distinguish
Q:What does 70 of the e7015 electrode mean?
There is E7015 in AWS A5.1, equivalent to J507 welding rod. And the national standard also has E7015, that is, J707 welding rod. I don't know which one the landlord is asking. If you are asking for J707 welding rod, then the third floor answer is very good.
Q:Why does the welding rod adhere to the weldment?
1, welding current is too small.Please refer to the instruction of welding current in electrode box, choose the suitable welding current according to the welding position.2 basic electrode welding with AC welder.J426, J506 and other low hydrogen potassium welding electrodes must be welded with BX series alternating current welding machine with no-load voltage above 70V. The lower the no-load voltage of the welder, the easier it is to stick the welding rod.3, the welding rod model is wrong.J427, J507 and other low hydrogen sodium welding rod, unlike low hydrogen potassium electrode containing arc stabilizer, the welding rod must be welded by DC welding machine. AC welding machine will stick welding rod, cannot arc.4, improper operation. Basic electrode (low hydrogen potassium welding rod, low hydrogen sodium welding rod, etc.) shall adopt the method of striking and striking arc. Just as a match, the end of the welding rod and the construction of contact, a slight rub can ignite the welding arc. If the direct striking method is used, the welding rod is unavoidable.5, technical problems. The arc welding rod should lift the arc 1-3 millimeters rapidly and enter the normal welding mode. Otherwise, long time welding rod and workpiece short-circuit will dip electrode.
Q:Why is the hydrogen content in the weld lower than that of the alternating current when the acid electrode is welded by direct current?
The welding process is all on the increase of hydrogen from hydrogen weld, welding material, workpiece oil rust and water vapor in the air, so the general basic low hydrogen welding welding before drying;When AC welding of basic electrode, the arc is unstable, and the DC reverse connection is more stable than the direct current connection. Therefore, the welding torch is low and the welding arc is relatively stable;DC electric arc welding, welding welder with positive output, torch (holder) cathode is connected with the output end of the wiring method, called "connect law" also known as positive;DC electric arc welding, welding welder with negative output, torch (holder) connection is connected with the output end of the cathode, called "reverse method" is also known as reverse polarity.When welding with a DC arc welding machine, the welding heat obtained by the direct welding method is high.In the MIG welding, weld reverse DC deep shallow, weld and weld pool is flat, is conducive to the gas pool in the liquid metal, and the arc than is then stable, the protective effect of welding material of gas production slag is better.
Q:Type meaning of welding rod
The carbon steel welding rod E represents the welding rod, and the first two figures indicate the minimum value of the tensile strength of the deposited metal. The third position indicates the welding position, and the three or four digit combination represents the type of welding current and the type of the coating.The stainless steel electrode "E" represents the electrode, and "E" is the digital code indicating the chemical composition of the deposited metal. "-" the two digits behind it indicate the type of the coating, the position of the weld and the type of welding current.Specifically, you can see GB5117, GB983.Such as structural steel electrode J422, J is steel structure code, 42 said that the tensile strength of weld metal grade (MPa value 1/10), said at the end of the 2 type of coating and the type of welding power source; and as the austenitic stainless steel electrode, A132, A austenitic stainless steel electrode of the code, the first digit said the main chemical composition of weld metal (Cr, Ni) level consists of second digits, in addition to Cr, Ni other metal components brand variety.The electrode model is based on the mechanical properties of the weld, the type of the coating, the location of welding and the type of welding current. Such as E4315, E is said 43 electrode, said the tensile strength of the deposited metal is minimum, third digits 0 and 1 indicate the position of welding, all position welding, suitable for welding 2 and 4 for horizontal fillet welding, vertical down welding, the last one said the current type and type of coating.
Q:How can I distinguish the basic electrode or the acid welding electrode from the welding rod number?
General electrode brand will see E308-15 or -16 or -17,Suffix 15 means that the electrode is alkaline, and the reverse polarity is welded;Suffix 16 means that the electrode can be an alkaline coating, or a titanium or a calcium titanium based coating for both hand and dc;The suffix 17 is a variant of the drug skin type 16, which means that the electrode is made of titanic acid type and can be used for both hand and DC purposes.The ingredients and operation characteristics of the rings 25 and 26 are similar to those of the electrode type 15 and 16. The specifications of the type 15 and 16 of the electrode type are also suitable for the type 25 and 26 of the coating types. According to the nature of the electrode coating, the electrode can be divided into two categories: acid electrode and basic electrode.Drug skin contains a large amount of acidic oxide (TiO2, SiO2, etc.) electrode, known as the "acid electrode.".The skin contains many basic oxides (CaO, Na2O, etc.) called alkaline electrode.Acid electrode can AC-DC, the welding process performance is better, but the weld mechanical properties, especially the impact toughness is poor, suitable for welding low alloy steel for low carbon steel and low strength, is the most widely used electrode.The basic electrode has strong desulfurization and dephosphorization ability, and the coating has the function of hydrogen removal. The hydrogen content of welding joint is very low, so it is also called low hydrogen type welding rod. Basic welding seam has good crack resistance and mechanical properties, but poor technology performance, general DC power supply welding, mainly used for important structures (such as boiler, pressure vessel and alloy steel welding etc.).
