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:How to select welding rod for welding Q245R Q345R?: Q245R is a low carbon steel used in containers, and R is the initial letter of container steel.Q345R is a low alloy steel used in containers. R is the initial letter of container steel.Q245R: parent material category, group code: Fe-1-1SMAW electrode model (general structure) E4303. Electrode number: J422.SMAW electrode model (important structure) E4316/E4315. Electrode brand J426/J427.Welding rod standard number: NB/T 47018.2Q345R: parent material category, group code: Fe-1-2SMAW electrode model (general structure) E5003. Electrode number: J502.SMAW electrode model (important structure) E5016/E5015. Electrode brand J506/J507.Welding rod standard number: NB/T 47018.2

Q:Why should the electrode be baked before use?: I don't want to tell you anything that is very theoretical and very textbook. Our project is very wet in the south, so the steel production base often does.The main reason for baking the electrode is (or to prevent) the welding rod from being wetted.Welding rod after wetting, in the welding of workers will indirectly cause more slag, more bubbles, the current is not good control, burn the main tendons, and the strength of the steel bar connection will not meet the design requirements.

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:Drawings require E43 electrodes, the market says 422 of the electrode, the package is written on the CFE422! Q235B seamless steel pipe should be welded. Can you tell me what kind of electrode should be used then?: Dissimilarity。 E43 is the electrode type, and J422 is the electrode (concrete) brand.Welding rod brand: J422, model: E4303 belongs to titanium calcium type low carbon structural steel welding rod. For Q235 grade low carbon structural steel welding. Acid welding rod. AC welding machine DC welder and welding rod. Good welding process, easy to remove slag. All position welding.It should be said: E43 model series welding rod, and J42 brand series of welding rod matching specifications.Such as: Brand: J422, corresponding model: E4303,Brand: J426, corresponding model: E4316,Brand: J427, corresponding model: E4315.

Q:What kind of welding rod does 1Cr13 steel plate use?: Usually in 1Cr13 and other dissimilar materials welding, choose A302 welding rod, welding should not preheat and after heat, but after welding, it is best to increase heat treatment (of course, no heat treatment is also no problem)It is better to use G202 or G207 if welding of 1Cr13 same kind of material, preheating before welding, heat after welding and heat treatment

Q:What are the welding electrodes?: The utility model relates to an electric welding rod, which belongs to hardware engineering consumption equipment. Welding rod is listed as "manufacturing industry" in the industry classification standard of People's Republic of China: other metal products are manufactured.Brief introduction of electric welding strip:The electrode consists of two cores and coating composition. The electrode is coating in metal welding core (coating), uniform centripetal pressure applied to core. The electrode of different types, different cores. 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.

Q:What type of welding machine does not use electrode welding machine?: In addition to all the outside welding manual welding and manual welding AC DC do not need electrode, such as argon arc welding (filler wire or wire filling), gas welding (CO2, MIG, MAG), submerged arc welding, resistance welding (spot welding, projection welding, seam welding, butt welding), laser welding, diffusion welding, explosive welding, plasma welding, diffusion welding, brazing, etc..

Q:What is the difference between tin strip and electrode?: Tin is made of tin and has a low melting point. It is commonly used for the connection of small items such as circuit connections of integrated circuits. The principle is that the crystal is melted by heating.The outer electrode is a mixture of phosphorus and other combustible material, the middle is iron, high melting point, used to connect large metal objects, the work is a glare, hurt the eyes, the working principle is the crystal of heat melting and high pressure arc discharge.The electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece. Consists of two parts covering and core wire. Depending on the melting of the crust and filling the metal into the weld, it becomes the main component of the weld metal, which is called a welding rod.Tin is a kind of product in solder, tin can be divided into a tin lead and lead-free solder two, are used for welding circuit board. Pure tin manufacturing, wettability, good fluidity, easy to Shangxi. Bright spot, full, no weld and other undesirable phenomena. Add adequate antioxidant elements, strong antioxidant capacity. Pure tin manufacturing, tin slag less, reducing unnecessary waste.

Q:J807 electrode specification: Brand: J807, model: E8015-G.Fused metal chemical composition: carbon is less than or equal to 0.09%, manganese is greater than or equal to 2 and less than or equal to 0.40%%, silicon molybdenum, 0.80 ~1.00%%Belongs to low hydrogen and sodium type low alloy high strength structural steel welding rod. DC reverse polarity is adopted. All position welding. Excellent manufacturability and crack resistance.Used for welding of 14MnMoNbB steel and other low-alloy structural steel of corresponding strength.

Q:2.5 what is the current of the welding rod sheet?: Welding sheet iron generally use 43 kg class acid electrode J422, current in 80-100A, welding thin sheet iron current should not be too small, the current is too small, but easy to weld through.
