- Q: What is the substance on the outside of the electrode?
- 1, welding electrode is divided into acidic and alkaline electrode. Acidic oxide as the main component of acid coating, such as silica, titanium dioxide, ferric oxide. Alkaline oxide as the main component of alkaline electrode, such as marble, fluorite and so on. The role is to protect the welding process is not oxidized, produce a lot of heat welding in the process of2, the electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
- Q: When welding, for example, 3.2 of the electrode should choose how much current
- The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
- Q: Electric welding machine welding, welding rod old stick metal, welding rod burning red, very scary
- 1, this is because you are novice unskilled operation caused,2, teach you two kinds of arc welding method:1) scratch: this method is easier to control, but it is easy to damage the surface of weldment. The welding rod shall be aligned with the weldment at first, then the electrode will be lightly scratched on the surface of the weldment as a match. The arc will be ignited, and then the electrode will be improved by about 2-4mm, and it will be stably ignited.2) direct method: the end of the electrode aligned welding parts, and then bend the wrist, so that the electrode slightly touched the weldment, and then quickly put the electrode about 2-4mm, arc ignition, wrist flat, so that the arc to maintain stable combustion. The method does not scratch the surface of the weldment and is not limited by the size and shape of the weldment surface, so it is widely used in production. But this method is not easy to master, the welder must have higher proficiency in operation.3) starting welding: after the arc is ignited, the arc will be lengthened a little longer, the butt welding parts should be preheated as necessary and appropriate, then the arc should be pressed properly and transferred to the normal welding procedure.3, usually practice more, do not worry, I believe you will succeed.
- Q: J422 welding rod, 10MM steel plate.
- A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.
- Q: Don't long winded, concise, thank you!
- 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: 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
- Q: Method for using welding rod heat preservation barrel
- Put the baked electrode into the barrel and take it with you. If the cooling, with the original plug a clamped welder + pole, a clamp of electric welding machine can be heated to very.
- Q: Is there any difference between welding wire and welding rod? What is the production process of welding wire? What kind of equipment do you need?
- Rod and wire are welding materials, before only electrode, later with the development of science, some of the drawbacks of the electrode show out, such as weld joints more slow, wire appear to make up for some of the drawbacks of the electrode, but now there are some electrode to his advantage, but the annual output has been wire phagocytosis, especially the flux cored wire is the main direction of future development.As for the production process, first of all, the raw material processing, peeling, phosphating, through the mold drawing, pickling, washing, copper plating, polishing, etc..
- Q: Which prawns can help give an answer, all kinds of stainless steel electrode guarantee period is how long, this has specific standards can be found? Thank youThe best hope for friends to answer, you can attach the standard name.
- Save good words is two years, do not damp, and if it is relatively high requirements, the use of baking, remove moisture.
- Q: I want to buy an electric welder and need to fill in the specifications and models. I don't know how to write it
- The electrode thickness with the welding machine type does not have what relation, mainly with the welding of the welding current on the size of the 3.2 electrode electrical machine above the amount of output current of 200A welding machine, 160A welding of thin sheet metal, can also be slightly bigger, the thickness is not.
