What kind of welding rod is used for No. 55 steel?
- To choose J506 or J507 welding rod, preheat 150~200 degrees before welding, heat preservation after welding. Or choose the electrode with higher strength grades
What wire and electrode are used for welding between s32168 and s31603?
- Electrode selection A022Welding wire selection H03Cr19Ni12Mo2s
Can welding of stainless steel plate and ordinary steel pipe be welded with thj422 welding rod?
- No, stainless steel electrodes should be selected.s
Is the electrode electrically conductive?
- Because there is wire electrode conductive, synthesis of various substances, covered up, welding machine output two AC machine is not divided into wire, welding wire, welding machine DC cathode to anode grounding wire, two output voltage will be encountered after the ignition, the electrode is electrically conductive. The electrode was encountered after the ignition, melting body, outside of the medicine is to protect the melted wire, prevent the pores, electrode head with no welding electrode holder, if the flux is not conductive to clip, also cannot be weldeds
Is the resistance of welding electrode large?I don't know much about welding. I want to know the general resistance of welding electrode. I also want to know the difference between welding and sub arc welding
- Arc welding is a sudden disconnection, producing high voltage arc, burning welding rods
4 of the electrodes, what is the weight of a case?
- As far as I know, the welding rod is not the pipe specification. They are 5 kilos a pack. One case is 20 kilos. At least the Atlantic has this kind of packing. There are two main kinds of welding rod. There is no need to be as complicated as the previous net friend, the acid welding rod and the basic welding rod. Acid electrode, that is, the most common, such as 422. This electrode is generally easy to use, not demanding, carbon steel, ordinary iron can be used, the basic electrode contains more. Mainly used for higher welding requirements. Boiler aspect. Such as 317.507.307., these 3 are carbon steel. There are 137.407 stainless steels. Also used for boiler pipes. Pressure vessel aspects. Specifications are common for 3.2, 4, 6, 2.5. That's all I knows
What enterprises use more welding electrodes?
- Shipyard, boiler plant, steel structure, locomotive, automobile, construction machineryBuilding construction; large building; exterior wall decoration.s
What does "E7016" mean? What should I pay attention to when welding? Can I weld the pressure vessel (pressure 1Mpa)?
- E stands for welding rod, 70 represents tensile strength of weld metal, 700MPa is 1, welding rod is suitable for all position welding, and 16 is low hydrogen direct current.s
