1.Application of welding electrode:

The welding electrode E6013 is widely used on both AC and DC in all positions and suitably for welding sheet metal structure made of low-carbon steel, such as ships, vehicles, building, and general machinery.

Used for welding structures made of carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. Most widely used for welding some key structures like shipbuilding, mechanical manufacture, pressure vessels, boilers, petroleum machinery, chemical machinery, hoisting machinery, etc.

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: 2.5 what is the current of the welding rod sheet?: Welding sheet iron generally use 43 kg class acid electrode J422, current in 80-100A, welding thin sheet iron current should not be too small, the current is too small, but easy to weld through.

Q: Electric welding machine welding, welding rod old stick metal, welding rod burning red, very scary: The arcing contact electrode and the work piece the wrong way, do not use too much force at the contact electrode, which is slightly floating, in addition to improve the current, can be adjusted according to the electrode packing instructions, you practice more, don't worry, I believe you will succeed.

Q: E9015-B9 is a welding rod for which steel is welded: 1, E9015-B9 is the United States brand of welding rod, GB is about R407.2 and E9015-B9 are heat-resistant steel welding rod, used for welding heat-resistant steel.

Q: What kind of welding rod used for cast steel?: Layman questions must be answered in large vernacularCast steel can be considered as rolled steel of the same grade.Will the steel rod be selected?

Q: Is there any difference between E308 welding rod and 308?: E308 is the electrode type, that is, corresponding to the domestic A102 stainless steel electrode brandIn addition, there are R308, A308, and so onMethod for indicating welding rod type:Z said at the beginning of cast iron electrode and low temperature steel nickel alloy electrode with W Ni, R, heat resistant steel electrode surfacing electrode D, chromium stainless steel electrode with G A said, TS said, with a special electrode silver electrode HL, copper and copper alloy rod T, aluminum and aluminum alloy L, welding gas welding rod HS

Q: What does 70 of the e7015 electrode mean?: The method of welding rod number is as follows: the welding rod letter "E" means welding rod;The top two digital said the minimum value of the tensile strength of the deposited metal is kgf/mm - unit. (70kgf/mm = - 690 MPa)Third digit electrode welding position, "0" and "1" electrode for all position welding (flat, vertical, horizontal, upward), "2" is suitable for welding and fillet welding electrodes, "4" is suitable for vertical down welding electrode;The third and fourth bit numbers indicate the type of weld current and the type of coating.After fourth digits, additional "R" is added to indicate the resistance to moisture absorbing electrode. Additional "M" is used to indicate the resistance to moisture absorption and mechanical properties. The electrode with special requirements is added with "-1", indicating that the electrode with special requirements for shock performance is attached.

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: Add 100 points to the approved answer before 2, plus 50 at 3. Beg speed: E5015 welding rod, also known as J507, J strip structure steel electrode. It belongs to low hydrogen sodium basic electrode. E stands for welding rod, and 50 represents tensile strength 50kgf/ mm215 represents low hydrogen and sodium type, suitable for all position welding of flat, horizontal, vertical and vertical positions. DC reverse welding is adopted.G507, the welding rod does not have this model.

Q: What is the corresponding brand number of electrode model E55?: E55 stands for: E carbon steel welding rod, low alloy steel welding rod, the strength is between 440 ~540MPA, and the main alloy is Mn-Si-Mo.E55 series welding rod:E5511-G, the Chinese brand is J555 AWS, and the model is E8011-G:Cellulose type AC and DC+ are used for vertical butt welding of low alloy steel tubes, girth welding, butt welding, and vertical structure welding of corresponding strength grade.E5516-G, the Chinese brand is J556 AWS, and the model is E8016-G:Low hydrogen type AC and DC+ are suitable for welding medium carbon steel and 15MnTi, 15MnV and other low alloy steel structures.E5516-G, the Chinese brand is J556RH AWS, and the model is E8016-G:Low hydrogen type AC and DC+ are suitable for pressure vessel, offshore platform, ship and other low alloy steel structures.E5515-G, the Chinese brand is J557 AWS, and the model is E8015-G:Low hydrogen type DC+ is suitable for welding medium carbon steel and 15MnTi, 15MnV and other low alloy steel structures.
