Features of Seleno's Phos Copper Silver welding rod:

1) Good fluency

2) Low cost

3) Perfect performance

4) For resistance brazing, gas flame brazing, high frequency inductionbrazing and furnace brazing

5) Joint strength high and conductivity good

6) Flux is necessary when brazing copper or copper alloys phos-copper-silver

7) Brazing alloys with low melting points have good 'wettabilty,'high strength and toughness

8) Ramp rate should be as quick as possible while brazing

9) Joints become bright gray, returning to original copper color once dipped into a 10% sulfuric solution

Q: What kind of steel bars are used for the two electrodes?: Their strength is different, J422 is 42 kg class, J502 is 50 kg class, steel model I don't understand. J502 welding thread steel is appropriate.

Q: Is it used for welding power plant construction?: Base metal is 10, 20 steel with J427Stainless steel with A102

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: What are the characteristics of SHJ507 welding rod?: SHJ507 is J507, and the SH in front represents only the manufacturer.J507 is a low sodium hydrogen electrode, it is a kind of basic electrode, welding steel structure in Q335 material, the tensile strength of E4315 is much larger relative to the common electrode (so do not on Q235 steel) because it is waste, the general welding force or steel structure dynamic load. For example, the ship, crane steel J507 welding rod diameter from 2.5, 3.2, 4, 5 can be carried out in all position welding, welding using DC welding machine, polarity reversal. If the same can not be used in the field of AC welding machine, butt weld forming large J507 quality sound shadow after welding is ugly (not the acid electrode), if the steel structure cover can be used for acid electrode. (. Requirement 507, there are 422 cover)

Q: What is the difference between A507 welding rod and J507?: Difference between A507 welding rod and J507 welding rod:A507 stainless steel electrode is a kind of pure austenitic Cr16Ni25Mo6 stainless steel welding rod used for welding the low consistency basic skin under quenching condition. The current should be considered too large during operation. A507 is a pure austenitic Cr16Ni25Mo6 stainless steel electrode for alkaline coating. DC reverse connection can be used for all position welding. Used for welding low alloy and medium alloy steel, dissimilar steel and rigid structure, and corresponding hot strong steel. Such as quenching of 30CrMnSi, stainless steel and carbon steel welding.J507 is a low sodium hydrogen electrode, it is a kind of basic electrode, can be Q235, Q245R, Q345R typical welding structure steel in steel, the tensile strength of E4315 is much larger compared to the common electrode, so the general welding force or under dynamic load of steel structure. J507 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using DC welder, polarity reversal. Of course, if there is only AC welder in the field, AC welder can be used, but the current needs to be switched on. The weld formation after J507 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used.

Q: Does the welding rod have a shelf life?: This does not necessarily depend on your preservation of the environment and the variety of electrodes, and some electrodes have been preserved for more than ten years, the use of performance is still very good. As long as it is not damp and the skin falls off, it can continue to be used.Material shelf life is not strictly required, the pressure vessel required if more than one year, should carry on the inspection, inspection qualified can continue to use, every year to conduct a test, you can still continue to use qualified.If the welding pool conditions, welding save no moisture, no deterioration, after inspection and acceptance, can still be used.If not assured, you can downgrade to adopt. There is not willing to do more information (welding rod to continue inspection of qualified data), can also be downgraded. Other industries, did not see the relevant standards requirements.Our welding wire has been produced in Japan in 1949. The welding rod has been produced in Japan in 60s and 70s. It has been well preserved. Now the chemical field inspection and maintenance are still in use. The effect is very good and the quality is not a problem.

Q: It's expired. What color is it? It's better to have screenshots: Sure.Welding rod can not be damp, otherwise it will seriously affect weld quality.

Q: Can white steel electrode weld cast iron?: I have not used white steel electrode, used 506 is not bad

Q: What brand of carbon steel electrode is the best?: For welding rod:Domestic brands, then, the best in the Atlantic, where the CHE58-1 is simply a classic product.Foreign brands, then, Lincoln, Esab and so on are also classic brands, Olin Kang is the best.

Q: Can the Q345A board be welded with 422 electrodes?What kind of welding is best?Thank you!: Q345 low alloy high strength steel is the former 16Mn steel
