Applications of Welding Wire:

Hardsurfacing of blower , screw , conveyor , mixer blades , speed-mullers etc.

Characteristics of Welding Wire:

MT-FZ30 deposits weld metal of high-Cr cast iron which contains a large amount of chromium- carbide.

The weld metal is suitable for wear-, heat-, and corrosive-resistant.

Note on Welding Operation

1. The welding machine for solid wire is applicable.

2. Pay attention to the adjustment of the feeding roller , because rigidity of MT-FZ30 is a little soft compared with the solid wire.

Q: What enterprises use more welding electrodes?: Small businesses and individuals now use more. Two oxygen is used for steel structure transmission. And then the site is OK

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: Requirements for welding electrodes for temperature and humidity: Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.

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 is the difference between electrode type and brand?: Model and brand are different, it is to see the material you have to weld the workpiece to match, ordinary use is 422 knot, special steel to use 506 knot, 507 knot

Q: What is a welding rod?: This is the process of welding is old, not now, is 2 with the welding steel head away, away from the 10~20MM, and then in the 2 sides of the 1 roots (2 with 1 of the state), one side welding requirement is 10D double 5D, help the section area of the reinforcement bars shall not be less than the main bar section 70%, the force is very good, is a waste of trouble long operation time (the weld is 4 times the length of the lap welding) of the good (space space)

Q: Electrode E4300 what does it mean?: 1, welding rod E4300 means.2, did you see the icon? Let me explain it to you.E - electrode,43- indicates that the minimum tensile strength of the deposited gold wire is 430MPa,0- indicates that the welding position is all position,Second, 0 indicates that the electrode coating is of special type.

Q: Which prawns can help give an answer, all kinds of stainless steel electrode guarantee period is how long, this has specific standards can be found? Thank youThe best hope for friends to answer, you can attach the standard name.: There should be some

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

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.
