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+

Q:Can ordinary electrode be used for welding cast iron?

No way！ Cast iron electrodes must be used! Ordinary welding rod welding porosity is too much, not solid.

Q:Please say a bit more detailed, you can weld the boiler's welding rod varieties, models are said...

Welding furnace electrode is the most commonly used J422 and J507 two.Because often used in boiler manufacture, commonly used steel is: sheet --Q245R (20g) and Q345R (16Mng)Profiles --20# (GB3087) tubing 20# (GB699)Among them, the electrode matching Q345R (16Mng) is J507, and the other three kinds of materials match with J422 electrode.

Q:What are the diameters of the electrodes?

The common diameter is 2.5, 3.24 (mm), also has 2mm, 5mm, generally not commonly used, very rare.

Q:What is the J422 electrode core material

The J421Z electrode is composed of two parts, core 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. 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. For welding of carbon steel and low alloy steel welding core, are mostly made of low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other components (see wire national standard GB1300 - 77). The reason of low carbon is a low carbon steel wire plastic, wire drawing is relatively easy, on the other hand can reduce the CO content of reducing gas, reduce spatter or porosity and increased weld metal solidification temperature, favorable for overhead welding. The addition of other alloy elements mainly guarantees the comprehensive mechanical properties of the weld, and also has some effect on the welding process performance and the removal of impurities.

Q:What's the difference between 422 and 506? What are their respective attributes?

506 electrodes and 422 electrodes, in addition to the strength level, the former is 50 kilograms, and the latter is 42 kg class,506 electrode for low hydrogen alkaline skin, although it can be AC and DC dual-use, but the best use of DC welding machine422 electrodes for calcium titanium acid skin, AC and DC can be

Q:Commonly known as "white steel electrode" what does it mean?

I produce stainless steel electrode, stainless steel wire and all kinds of special welding rod, welding wire

Q:I want to buy a small inverter welder, I heard that welding machine is very light, how heavy is it? It's the kind of carry. And how much is the price?. I wonder if the welder can use an acid welding rod? When welding, is it the same as the feeling of communication? I used the DC blow, it seems a little big. It's not good at all.. There is also a big point of 315 inverter welding machine, how much is it?.

I know an iron power welder. The 4750 yuan I bought last month is an inverter welder. Argon arc welding. Acid and alkaline welding rod can be. Now, all pipes in Shanghai are made of this kind of welding machine. It weighs about 20 kilograms. It's very convenient to use

Q:What are the characteristics of welding rod E6010? What are the main points of operation?

E6010Cellulose electrodeSee the attachment for details.

Q:When welding, for example, 3.2 of the electrode should choose how much current

The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
