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 is Mt -12?
MT-12 is a kind of low carbon steel welding rod, is Chinese more than 5 Minerals Import & Export Corporation Tianjin branch (hereinafter referred to as Minmetals Tianjin Corporation) brand products, its chemical composition is (%): C 0.09 Mn 0.40 Si 0.20 P 0.019 S 0.015Contrast chemical components, similar to J421, but higher than J421
Q:How to calculate the amount of electrode used in pipe welding?
According to the wall thickness of the pipe and the groove at the butt joint, the weld height is calculated, and the sectional area is calculated. According to the circumference of the pipe, the volume of a weld is calculated. The volume of the corresponding welding wire is the amount of the weldIt can also be multiplied by the number of welds and 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.
Q:What brand of welding rod or welding wire for Q345B material?
Optional electrode, if the force is smaller, J502 can be used by the force of J506, J507, welding wire available, H08Mn2SiA. two welding on the line.
Q:Does construction welding rod need to be re examined?
Don't want to do the material inspection (certificate and test report)
Q:Difference between ordinary electrode and tungsten electrode
First, the ordinary electrode is arc welding, is the direct consumption of materials in welding, is to rely on the skin to melt molten steel, not to be oxidized welding. Is the use of tungsten electrode argon arc welding, tungsten materials, prevent oxidation in protecting gas under high temperature, using current tungsten electrode welding wire and the material will be melted, the theory of tungsten consumption is minimal.Two and two kinds of materials are two kinds of welding methods. The arc welding is made with an electric welding rod, while the tungsten electrode is used in argon arc welding, but the tungsten electrode is only the electrode. The arc welding and the welding electrode act the same as the welding wire.
Q:Generally, how many packs are in one case and how many KG in one package?
A case of 5 bags, a pack of 5kg
Q:Shelf life of stainless steel electrode
Save good words is two years, do not damp, and if it is relatively high requirements, the use of baking, remove moisture.
Q:What welding Q235 and 16 steel, please enlighten Masters
It belongs to the welding of low carbon steel and low alloy steel. Using alkaline welding rod, it is enough to choose E43 series
Q:How are the electrodes made up?
The electrode composition is divided into two parts, metal core and coating (coating). It is composed of manganese, silicon, chromium, nickel, iron alloy, organic substance and so on.Core: generally use low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other ingredients.Coating: 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.).
