Q:What is flux cored wire?
There is a powder in the wire
Q:What does "TGS-308" mean?
TGS-308 is the wire grade refers to the production of Tiantai welding of 308 stainless steel solid wires, tungsten argon arc 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 kind of wire is ER80S-G and what material is it mainly welded to?
CHW-65ACompliance: GB ER55-GFairly: AWS ER80S-GDescription: CHW-65A is 600MPA grade low alloy high strength steel gas shielded welding wire. With the whole position of good performance of the welding process, welding wire has good weldability, in supine and transverse position, to meet the needs of field welding such as hydraulic steel structure, shipbuilding, power plants, boilers, petrochemical and other large welding products production and installation.Purpose: using the argon rich mixed gas is widely used in the protection of hydraulic steel structure, shipbuilding, power station, boiler and pressure vessel, petrochemical industry, engineering machinery, lifting equipment, transportation and other fields of 600Mpa grade high strength low alloy steel welding, such as HITEN610U2, 62CF, 15MnVN, BHW35 etc. the corresponding strength grade of steel.
Q:What kind of gas shielded welding wire for Q345 steel plate?
Q345 is one of the commonly used low-alloy structural steel grades, and the welding wires matching the strength are: GB ER50-6 copper plated solid low alloy steel welding wire.ER50-6 welding wire is equivalent to American Welding Association AWS's ER70S-6, Japan JIS's YGW12 classification society. In accordance with the classification society (ABS), Bureau Veritas (BV), Chinese Veritas (CCS), Norway Classification Society (DNV), Germanischer Lloyd (GL), Kr (KR), Lloyd's register (LR), ClassNK (NK) as approved by the classification society.The utility model has the advantages of strong oxidation resistance, strong oil stain and small pore sensitivity of the base material. Used for welding of 500MPa grade structural steel parts, including Q345.Can be used as protective gas welding 100 using carbon dioxide gas; can also be used for MAG welding, argon + carbon dioxide gas, mixed gas arc welding.The diameter of the welding wire is determined according to the factors such as the rated output of welding machine, welding current, welding machine load rate and base metal thickness.
Q:3003 what welding wire for aluminum plate?
3003 of the aluminum plate can be welded with 4043 aluminum silicon welding wire, and some people use 5356, specifically, which effect have you tried better?.
Q:What is the advantage of welding wire without copper plating?
The copper plating wire at the beginning to rust, but in the use of the process can also be found conductive, the worst is the operator in the use process of smoke inhalation of copper is harmful to the body, and the production process will emit large quantities of sewage (which contains alkali, acid, borax, copper sulfate) of serious pollution to the atmospheric environment; the production process is now copper coated wires, no sewage nor copper smoke, small splash, small smoke (no copper smoke), good shape, environmental protection and energy saving.
Q:What is the cause of the crack in argon arc welding at 304? It's all the same without welding wire
Causes of weld joint cracking in argon arc welding at 304:1, no argon or gas leakage will lead to welding when the welding seam cracks, check the use of welding torch leak, do a good job of gas sealing measures.2, and 304 material problems, some small factories to do more impurities, welding process can see impurities, welding can obviously see the middle crack. Choose pure 304 wire, more soft is true. (like a wire), otherwise.3, welding angle is smaller and the workpiece is 45 degrees, so that more easily welding workpiece4, secondly, when welding the workpiece, the welding machine should be preheated first, the temperature is not enough, it is easy to weld cracks and heat preservation after welding.Technique and essentials of double sided welding of argon arc weldingOne side welding double face forming technology is an operation technique with great difficulty in welding electrode. It is necessary to master the operation essentials and techniques to guarantee the welding quality and quality.To arc welding, for example, to master welding arc welding, single-sided welding double-sided forming operation technology, must master the "five main points", specific content: see, listen, accurate, short, control. Should also learn to "Six Skills" specific content: solid, start, transport, arc, joint, closing.
Q:Why should CO2 welding wire have Si and Mn elements?
Wire components should comply with the relevant standards and contains sufficient deoxidizing elements Si and Mn, because the binding ability of Si and Mn elements and O2 is greater than Fe, can effectively inhibit the oxidation of CO2 to Fe, CO to prevent the generation of porosity, at present most of the domestic wire CO2 using copper as a protective layer, and by electroless plating. Low strength combined with chemical plating, copper plating layer is not uniform, easy out of copper scrap, copper plating and easy to rust, so the surface quality of wire should be checked before use, to reduce the source of blowhole.
Q:What are the characteristics of fuses? What are the properties of welding wire?
A fuse is also called a fuse, and the IEC127 standard defines it as a fuse (fuse-link)". The utility model relates to an electric component which is arranged in a circuit and ensures the safe operation of the circuit. When the current flows through the conductor, the conductor will be heated because of the resistance of the conductor. And heat follow this formula: Q=0.24I2RT; Q is the heat, the 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of a conductor, T is the current through the conductor time; so the formula we can see that the principle of simple fuse.1 、 over current protection and over temperature protection. A fuse used for overcurrent protection is a fuse (also called a current limiting fuse) as it usually is.2. Fuses used for overheating protection are generally referred to as "temperature fuses"". The temperature fuse is divided into the low melting point alloy shape and the temperature sensitive trigger shape, as well as the memory alloy shape and so on. The temperature fuse is used for preventing the heating appliance or the heating device from being too high and the temperature is too high to protect.Welding wire is used as filler metal or metal wire welding material at the same time as conductive.1, in gas welding and gas tungsten arc welding, welding wire for filler metal;2. In submerged arc welding, electroslag welding and other gas shielded arc welding, the welding wire is both a filler metal and a conductive electrode.3, the surface of the wire is not coated with anti oxidation flux.
She adopts advanced Germany technology and facility to guarantee the product quality. All the products are manufactured according to the ISO 9001 standard. This company already pass the national welding material quality surveillance center examination and approval. Our company can manufacture welding electrodes and co2 welding wires in China.
