1.Structure of Welding Wire Descrition

Applicable for single pass and multi-pass welding of carbon steel and 500 MPa grade low alloy steel and is widely used in such fields as automobile industry, construction machinery manufacturing, ship building, metallurgical and mining equipment manufacturing, bridge building, petrochemical industry and pressure vessel manufacturing, etc. Also applicable for high-speed welding of sheets and pipeline steel.

CO2 gas-shielded copper-plated welding wire has excellent welding technological property: the electric arc is stable with less spattering, the appearance of welded joint is nice with good crack resistance: it applies to all-position welding.

Q: Is there a welding wire for gas shielded welding of stainless steel? What brands do you have?: Basically, gas shielded welding (Ya Huhan) itself has no special choice for welding wire, but the wire is selected by material and welding machine. That is to say, stainless steel welding wire can be used for argon arc welding, but according to the conditions of choice.Stainless steel wire is mainly divided into two kinds, one is solid core welding wire, and the other is flux cored wire.When welding wire is used, it is mainly to choose different welding wires according to the welding material.ER308H stainless steel wire is mainly used for welding 18Cr-8Ni stainless steel.ER309Mo stainless steel welding wire is mainly used for welding 22Cr-12Ni-2.5Mo steel.ER409Cb stainless steel welding wire is mainly used for welding of 409410 stainless steel.

Q: What wire is H08A? What wire is GB? What wire is HJ?: The average carbon content of H08A wire: our company: about 0.08%.According to GB/T3429-2002 standard(International Standard for steel wire rods for welding):Chemical composition (%)C = 0.1; Mn0.35~0.6; Si = 0.03; Cr = 0.2; Ni = 0.3; Cu = 0.2;S and P are not greater than 0.03.This is the chemistry in the national standard. I hope it will help you.HJ is an abbreviation for flux

Q: Which subjects should be included in the purchase of welding wires (auxiliary materials) in industrial enterprises?: Purchase wire industrial enterprises (auxiliary materials) as raw materials. Subjects included in the supplementary cost of production cost, no consumption of wire, the end do refund processing, according to the actual amount allocated to product cost.

Q: Carbon steel, with two, welding current, voltage, welding speed, wire diameter, thank you: Various parameters of CO2 gas shielded arc welding(1) wire diameter;The diameter of welding wire is usually chosen according to the thickness of welding piece, the position and efficiency of welding application. When welding in all position welding of sheet or plate, the welding wire below 1.6mm (called wire CO2 gas shielded welding) is adopted.(2) the welding current depends mainly on the wire feeding speed. The faster the wire feed, the greater the welding current. The welding current has the greatest influence on the weld penetration. When the welding current is 60~250A, that is, short circuiting transition welding, the weld penetration is generally 1mm~2mm; only when 300A or more, the melt body is obviously increased.(3) when the arc voltage is short circuiting, the arc voltage can be calculated by the following formula: U=0.04I+16 + 2 (V)At this point, welding current is generally below 200A, welding current and arc voltage of the best fit in table 2. When the current is above 200A, the formula for calculating the arc voltage is as follows. U=0.04I+20 + 2 (V)(4) welding speedIn semi-automatic welding, the welding speed of skilled welders is 18m/h~36m/h, and the speed of welding can be as high as 150m/h at automatic welding.(5) the extending length of welding wire;The extending length of general wire is about 10 times of the diameter of wire, and increases with the increase of welding current.(6) the normal welding gas flow, 200A has been under the sheet metal welding and CO2 welding flux is more than 10L/min~25L/min.200A, the flow of CO2 for large specification of 15L/min~25L/min. thick wire automatic welding for 25L/min~50L/min.

Q: 3003 what welding wire used for aluminum welding, I have tried ER4047, but the aluminum plate has melted, the welding wire has not melted, I used 4MM welding wire. And you said to me is not the aluminum welding wire or other reasons, I should use what types of aluminum wire: It's not a wire problem. Is it argon arc welding or?

Q: A bottle of argon 40L used for welding, how long or how many wires can be welded? What's the price of argon now?: The total volume of argon gas can be calculated in this way: 40*150=6000 litres also take into account the actual filling pressure and the remaining gas at the end of the cylinder, so the amount of actual use must be less than 6000L.In the process of use, we should consider the welding method, manual operation, general 8-15L/min, mechanical or automatic continuous welding, the use of flow should be big.The market is based on the amount of argon filling volume, the size of the bottle is estimated to be almost. Ordinary argon 60-75 yuan / bottle unequalThe higher the purity, the more expensive the price.

Q: What welding wire do 15CrMo and 1Cr5Mo use?: If the crack resistance is good, the ER309 or nickel based wire can be used

Q: The role of silicon in stainless steel welding wire: Silicon is added as a deoxidizer, and its action is stronger than manganese. It can eliminate the influence of FeO inclusion on the quality of steel. Stainless steel wires, such as ER308, ER308L, ER316, ER316L and so on, contain different components of silicon

Q: Is there any difference between stainless steel wire and stainless steel wire?: There are some differences, but in no case of stainless steel wire welding can also be used instead of a stainless steel wire, wire wire more than kinds of trace elements, metal elements in several burning rushed to fill in the welding process, the joints reach the same performance with the parent material
