FAQ

What specification should be used for the three - step steel electroslag pressure welding electrode?

If the level of 32 thread steel bar is HRB335 (original two grade steel bar), E4303 shall be used for bar welding and lap weldingGrade HRB400 (original three grade steel), bar welding, lap welding using E5003Grade HRB335 (original two grade steel), groove welding using E5003Grade HRB400 (original three grade steel), groove welding using E5503

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!)

What's the model of lap welding for two grade steel bars?

You should first look at what is the project of the Ministry of communications and the Ministry of water resources, the other I know better, the Ministry of construction and the Ministry of Railways is not clear, each industry standard is not the same, so you have to figure out is what industry.If it is the Ministry of communications project, two steel bar can use E43 electrode, but the Ministry of water resources can not, need to use E50. These are found on the corresponding construction codes for reinforced concrete

J422 welding rod, 10MM steel plate.

How is caught in the electrode holder do not have much relationship. The key is the angle between the electrode and the workpiece, horizontal fillet welding is quite appropriate at about 45 degrees.

What kind of welding rod used for HRB500 steel bars?

E60xx welding rod for HRB500 steel bar

How to weld stainless steel electrode?

Eighty hours in advance drying 400 hours, the current fast welding

What is the difference between tin strip and electrode?

Tin is made of tin and has a low melting point. It is commonly used for the connection of small items such as circuit connections of integrated circuits. The principle is that the crystal is melted by heating.The outer electrode is a mixture of phosphorus and other combustible material, the middle is iron, high melting point, used to connect large metal objects, the work is a glare, hurt the eyes, the working principle is the crystal of heat melting and high pressure arc discharge.The electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece. Consists of two parts covering and core wire. Depending on the melting of the crust and filling the metal into the weld, it becomes the main component of the weld metal, which is called a welding rod.Tin is a kind of product in solder, tin can be divided into a tin lead and lead-free solder two, are used for welding circuit board. Pure tin manufacturing, wettability, good fluidity, easy to Shangxi. Bright spot, full, no weld and other undesirable phenomena. Add adequate antioxidant elements, strong antioxidant capacity. Pure tin manufacturing, tin slag less, reducing unnecessary waste.

Is there any difference between E308 welding rod and 308?

You are not engaged in welding, this problem is puzzling. E308 is the electrode type, that is, corresponding to the domestic A102 stainless steel electrode brand. 308, a single number, what does not mean ah, including E308, R308, A308, and so on, who knows what you mean?
