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: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 brand of welding rod or welding wire for Q345B material?: J507 welding rod, welding wire is TIG-J50

Q: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 rod

Q:What specification should be used for the three - step steel electroslag pressure welding electrode?: 1, three grade rebar electroslag welding electrode with 3mm diameter wire can be.2, screw steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.3, 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:Can the Q345A board be welded with 422 electrodes?What kind of welding is best?Thank you!: Yes, it does matter. Using J507. Because they are all in the 50 kilogram class.

Q:What are the characteristics of welding rod E6010? What are the main points of operation?: E6010Cellulose electrodeSee the attachment for details.

Q:Why do I use J422 electrode iron rail welding after their split seam. Later, the use of 506 electrodes did not have such a situation, I would like to ask what the rail contains? Yes. Is my J422 electrode fake? And... Is it my technique? Maybe the rails contain special ingredients? The person who knows it will answer immediately, "why does the seam split itself?": J422 is a titanium calcium type coating, acid electrode, tensile strength is more than 420MPa; the mechanical properties of rail, which is an indicator of tensile strength, mechanical properties of the rail are as follows:Steel tensile strength /MPa elongation / rail tread hardness% center line (HB)U71Mn, UIC900A = 880, 260~300 = 10PD3, BNbRE = 980, 280~320 = 9EN260 = 880 = 10 260~300 seen from the rail, the tensile strength is more than 880MPa, but the J422 tensile strength is more than 420MPa, so they will split the weld. J506 electrode for low hydrogen potassium type coating is added on the basis of the J507 formula in the arc stabilizing agent amount, the main welding electrode equivalent strength steel, low-alloy steel, ship steel and pressure vessels, such as 16Mn, 09Mn2Si etc.. Belong to the high manganese steel electrode, is the implementation of the "national standard" GB98485 surfacing electrode, electrode, the work hardening is particularly high, which improves the Mo crack resistance and wear resistance, hardened up to HB = 450-500. Higher than the rail 320, so the 506 welding rod welding rail, welding seam will not split.

Q:How are the electrodes made up?: The electrode composition is divided into two parts, metal core and coating (coating). It is composed of manganese, silicon, chromium, nickel, iron alloy, organic substance and so on.Core: generally use low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other ingredients.Coating: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.).

Q:What type of welding rod is needed for the construction of three grade steel bars used in construction?: In the construction industry, the second grade reinforced bar and the third grade steel bar are called in the past (old standard), and the new standard is replaced by the second grade reinforcing bar HRB335 grade steel, and the third grade steel bar is changed into HRB400 grade steel bar.In brief, these two kinds of reinforcing bars have the same points: they belong to ordinary low alloy hot rolled steel bars, all of which belong to ribbed reinforcing bars (commonly known as rebar), and can be used in ordinary reinforced concrete structures.The main differences are: 1. grades of steel are different (chemical composition is different). HRB335 grade steel is 20MnSi (20 MN SI); HRB400 grade steel is 20MnSiV or 20MnSiNb or 20MnTi.2. with different strength, tensile strength and compressive strength design of HRB335 grade steel is 300MPa, tensile strength, compressive strength design of HRB400 grade steel is 360MPa. The tensile strength and compressive strength of the welding rod J422 are 420MPa.3.. Because of the difference of chemical composition and ultimate strength of steel, they are different in toughness, cold bending and fatigue resistance.

Q:I use 2520 plates rolled into the pipe, I would like to ask you heroes: what type of welding rod with this? This tube is used on a carburizing furnace, with a temperature of 990 degrees: MG610MG610 is a universal stainless steel welding rod, used in various grades of stainless steel, advanced, all-round welding alloy, high corrosion resistance and high heat resistance, heat resistance temperature up to 1200 degrees. MG610 has good weldability, in a variety of circumstances, a very small splash, and easy to slag removal.Generality：MG610 can be used to weld various grades of stainless steel and carbon steel, especially for welding 310314410430 and similar stainless steels and other alloy steels. Fully austenitic structure means no sigma phase occurs.Application example:Such as: furnace parts, high temperature fan blade, steel ladle, heat treatment container, high temperature pipeline and so onMechanical properties:Tensile strength: 100000 psi / 689 inches per square inchYield strength: up to 65000 psi / 448 inches per square inchElongation 40%Current type: AC/DC+
