- Q:What kind of welding rod is used for No. 55 steel?
- No. 55 steel belongs to medium carbon steel and its weldability is poor. It should be preheated before welding. General structure arc welding using E4301, E4303, E4311, E4313, E4320 or J422 welding rod can be. The stress (main body) structure arc welding uses E4315, E4316, E5015, E5016 or J425 welding rod.
- Q:Why should the electrode be baked before use?
- Ordinary carbon steel electrode can not be used, but other electrodes, especially white steel, must be baked, because the welding rod welding when there will be holes

- Q:Can welding of stainless steel plate and ordinary steel pipe be welded with thj422 welding rod?
- J: stands for structural steel welding rod.42: two figures indicate that the minimum value of tensile strength of deposited metal is 42kgf/mm2 (412MPa), and the minimum value of the yield strength of deposited metal is 34kgf/mm2 (430MPa).2: third digit "2" indicates that the type of coating is titanium calcium type, direct current or AC power supply.According to the national standard GB/T5117 - 95, it is E4303 type ordinary carbon steel welding rod.Two, stainless steel and ordinary steel can be welded, the electrodes used must be the welding of the stainless steel or stainless steel welding rod or wire E31015 E31016.Three, in general, does not recommend the use of stainless steel and carbon steel welding in one place, the use of flange of stainless steel and carbon steel is more appropriate, because long-term exposure, will produce "carburization reaction", the impact characteristics of stainless steel.
- Q: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 welded
- Q:What are the welding electrodes?
- Not a single electrode metal material, which is composed of a metal core and coating. The electrodes of each model are different in composition.
- Q:What are the characteristics of welding rod E6010? What are the main points of operation?
- Features: all position welding of pipe, vertical down welding, single side welding, double sided forming, welding speed.Main points: unpacking as soon as possible, high requirements for welders
- Q:J807 electrode specification
- Gas shielded flux cored wire with high strength steelSHJ807Description: SHJ807 is a metal cored low alloy high strength steel welding wire. When welding, the welding wire is connected to the positive pole and 80%Ar+20%CO2 mixed gas or 100%CO2 is used to protect the welding wire. The welding process has good performance and high welding efficiency. Deposited metal has good crack resistance and high toughness. The workpiece should be preheated in the range of 250~350 centigrade before welding and be treated by tempering at 620 DEG C after welding.Application: it is used for welding high strength steel of relative strength grade, and can also be used for surfacing of ordinary wear-resistant parts or for transition layer of hardfacing parts.Typical chemical composition of deposited metal (%)Ingredients C, Mn, Si, S, P, Cr, MoThe measurement value of 0.065 1.63 0.3 1.05 0.48 0.025 is less than or equal to 0.025Typical mechanical properties of deposited metal: (690 * 1H tempering)Tensile strength (o b) Mpa yield strength (by 0.2) Mpa (5)% elongation impact energy of Akv (-40 C) JMeasured value 8207601838Recommended parameter: (DC+) (1.2mm)Welding current (A), welding voltage (V), dry stretch length (mm), gas flow (l/min)200~260 28~32 15~25 20Matters needing attention：Remove rust, oil stain and moisture before welding.Remove welding slag between welding layers, and avoid slag inclusion.When welding, preheating and post heat treatment are carried out according to process requirements.Welding wire should be kept in a cool and dry place. It can be used up in time.
- Q:Excuse me: can J422 welding rod not be used for HRB335 steel bar welding? Where there is such a rule, I see the norms can use ah.
- JGJ18-2003 regulations for welding and acceptance of reinforcing steel bars 3.0.3:HRB335 in the case of bar welding and lap welding, the use of E4303 (GB/T 5117, E4303), both CHE422, that is, commonly known as J422.Table 3.0.3 provides as follows
- Q:What are the requirements of steel structure for electrode?
- E43 series welding rod for common steel structure Q235Q345 material of steel to use E50 series welding rodWelding between Q235 and Q345 steels requires the use of E43 series electrodes
