FAQ

What is the price of titanium - calcium welding rod and low hydrogen type electrode?
Low hydrogen type expensive, different manufacturers, the price is very different
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.
What kind of welding rod does 1Cr13 steel plate use?
If used in high temperature situations, G202, but welding is troublesome, preheating before welding, heat treatment after welding, heat treatment should be carried out. If it is not high temperature occasions, A402 austenitic electrode is best. Preheating, welding, heat treatment, heat treatment are not necessary before welding.
What kind of welding rod used for HRB500 steel bars?
E60xx welding rod for HRB500 steel bar
Who knows a package of ordinary 422 electrode, how many roots ah, small packets of that kind, a small package, how much money, I would like to know how much an average electrode, a little difficult
3.2 per kilo, 32 roots. 4 in diameter, 17 per kilogram. 5 in diameter, 11 per kilogram.5 kilos per package. Usually 20 kilos per box. (the difference is about 2.) 3.2 of the stores sell around 25 yuan a pack.An average of 0.156 yuan and 3.2 electrodes are considered.
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.
How can I distinguish the basic electrode or the acid welding electrode from the welding rod number?What are the basic electrode models?What are the types of acid electrodes?
The number of electrodes from 0 to 6 is acidic, and 7 to 9 is alkaline
What's the difference between two oxygen welding and common electrode welding? What are the advantages and disadvantages?
Now, there are still two people suspected of welding costs?Do not know that science and technology is the primary productive force?!Said the first two welding material, welding wire electrode 8 dollars a kilogram, 6 yuan a kilo, looks cheap electrode.You have to see how much of the filler metal left in the weld after welding is equal to the price.1, the outside of the electrode coating, and finally the welding slag and protective gas, does not belong to the filler metal.2, each electrode has a welding rod head, at least 5 centimeters, have to throw away, does not belong to the filler metal.3, welding rod splash, splash of metal, does not belong to the filler metal.In addition, other costs, welding rod to dry, need oven, heat preservation barrel, heating electricity, throw away the welding rod.Let's talk about the same welding power, welding, welding heat input two is small, costs less power, more power inverter welder.What's more about efficiency and speed?.1, do not bake electrode, save time, minus a manual.2, do not change electrode, also need not from new arc, save time3, do not knock the welding slag off at least a coolie.4, for welding speed, two welding is three times of welding rod. (on this one, a welder can top three, you have to calculate how much money, artificial!)
