- Q: What kind of welding rod used for HRB500 steel bars?
- E60xx welding rod for HRB500 steel bar
- Q: Question Q235 weldability of carbon steel. What are the welding characteristics of those electrodes?
- Acid, alkaline welding rod can be. The acid welding rod E4303 has the advantages of good manufacturability, easy operation and poor mechanical performance. The basic electrode E5015 has poor mechanical properties and needs a DC welding machine with good mechanical properties.
- Q: Can A102 welding rod weld 316L?
- 316L belongs to ultra low carbon austenitic stainless steel, and if using A102, weld metal will reduce the ability to resist intergranular corrosion, so in the relatively high requirements of equipment, as far as possible using A022 welding rod.
- Q: Why should the welding electrode prevent moisture? What happens if you get soaked by water?
- Shanpaolv ah, do not know it. The electrode coating can be used in the welding process to re metallurgical and protect the weld pool and improve the weld formation. The skin of the medicine is affected with dampness, resulting in deterioration of the titanium, iron and calcium in the coating, and losing the original chemical properties. Even when drying, the deterioration of the compound in the welding will also produce water vapor, itching, hydrogen and other harmful substances to weld metal embrittlement. The change of the properties of the crust makes its physical properties different from those of the past, such as heat conduction, conductivity, melting point, melting effect, etc.. Influence re forming, resulting in thermal oxidation, metal cooling, excessive stress concentration, quenching...
- Q: What kind of welding rod does Q345 steel use?
- Weldability of Q345 steelQ345 low alloy high strength structural steel with carbon content of 0.18% ~ 0.20%, tensile strength equal to 470-630MPa. Q345 steel alloy content is less, good weldability, welding generally without preheating.But because the Q345 steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat. The preheating temperature of 16Mn steel at different plate thickness and different environmental temperature is shown in table 8.Q345 steel welding should be used in E50 type electrode, such as E5015, E5016 for alkaline electrode, the structure is not important, also can choose E5003, E5001 acid electrode. For the weldment with small thickness and narrow groove, E4315 and E4316 welding electrodes can be used.Table 8 preheating temperature of welded Q345 steelThickness of weldment (mm) preheating thermometer at different temperatures (DEG C)More than 16 of not less than of-10 DEG C - C without preheating preheated to 100 to 150 DEG C16 ~ 24 of not less than 5 DEG C 5 DEG C without preheating preheated to 100 to 150 DEG C25~40, not less than 0 degrees Celsius, not preheated, 0 degrees below 100~150 preheating temperatureMore than 40 are preheated 100~150 degreesSubmerged arc welding of Q345 steel H08MnA welding wire with flux HJ431 (open I butt welding wire with flux HJ431) or H10Mn2 (plate groove butt), when the deep groove weld of thick plate welding, welding wire with flux HJ431 H08MnMoA should be used.Q345 steel is the most widely used low alloy steel in our country at present,
- Q: Electrode: 506--J48-56 junction, Tianjin Bridge Welding Materials Group Co. Ltd. production. Is it possible to use an AC welder?
- J506 welding rod, using DC welder, AC welder can.
- Q: T107 purple copper electrode welding with what
- Inverter type DC welding machine is recommended. DC reverse short arc welding is adopted.Arc instability of AC welding machine.Silicon rectifier DC welding machine is affected greatly by network voltage fluctuation, reactor is not electronic current control, welding parameters are not accurate enough. Welding quality can not be achieved.
- Q: Hand welding electrodes 3.2 and 4 which are more commonly used?
- Personally think 3.2 is more commonly used.The welding between the sheet metal parts, the weld is not big, 4-5mm, 3.2 of the running better.For wider welds, 4 is recommended;
- Q: Welding rod for reinforcing cage of bridge pile foundation
- First of all, the electrode strength is greater than the strength of reinforcement, steel cage reinforcement is generally two bar steel bar, with 502 electrodes on it
- Q: What welding rod are used for welding of 304 stainless steel pipes?
- 304 stainless steel, that is, 0Cr18Ni9, when using electrode welding, you can use A102 (E308-16) or A107.If argon arc welding is adopted, H0Cr21Ni10 welding wire is needed.304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.The common marking methods in the market are 06Cr19Ni10, SUS304, in which 06Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.
