Product Description:

 

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:3.2 how much is a package of bridge electrode
This depends on what kind of electrode, such as J422 welding rod, 3.2mm package is five kg, the price is about twenty yuan. If it is J507 electrode and so on, the price will be higher, such as A132 and other stainless steel prices will be much higher.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.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:After the remaining number of suitable welding
After we calculate the utilization rate, the remaining 50mm of the welding rod is welded
Q:Difference between J422 welding rod and J502 welding rod
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:What kind of material is E4303 electrode?
E4303 is the international standard, the J422 electrode is a common name, it is a kind of acid electrode, titanium calcium coating, J structural steel electrode, 42 42kg/mm2 tensile strength of weld metal, melting the tensile strength of not less than 420MPa
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 kind of welding rod needs baking?
Ordinary carbon steel electrode without baking, it is necessary to roast pig iron electrode can improve the quality of welding electrode 2, the storage time is too long when damp, but not the core rust, coating without deterioration, electrode after drying, can keep the original performance and does not affect the use.The electrode drying conditions of various types of drug skins are as follows (reference value):The baking temperature of acid welding rod is 150~200 1HThe baking temperature of alkaline welding rod is 350~400 1HThe baking temperature of cellulose electrode is 80 DEG C and the temperature is 1.5 ~ 2HThe baking temperature of graphite type electrode is 200 1HNOUN interpretation:ElectrodeThe 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.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.
Q:Why does the welding rod adhere to the weldment?
I am a welding Education under normal circumstances so that you also appeared that the welder hand instability of basic work is not solid, the word "practice" learning when I have seen this kind of situation the old master directly let me practice!
Q:What is the substance on the outside of the electrode?
The electrode coating consists of various minerals, such as iron alloy, organic substance, water glass and other raw materials.Composition of electrode according to their different functions can be divided into arc stabilizing agent, fluxing agent, gas forming agent, deoxidizing agent and alloy slag agent, dilute agent and binder etc..
Q:What type of pig iron electrode?
Pig iron electrode is cast iron electrode, the vernacular is the pig iron electrode.Cast iron electrode commonly used model:CMC-E46NDirect welding on cast iron is very effective for metal wear of stamping dies. The first layer of welded metal is austenitic, and the martensite is from the 2 layer, so the wear resistance is good. Flame hardened cast iron can also be directly welded.CMC-MS64NCast iron welding rod, high strength and good plasticity. Suitable for gray cast iron and nodular cast iron, and can be machined.CMC-E47NDirect welding on cast iron is very effective for metal wear of stamping dies. The first layer of welded metal is austenitic, and the martensite is from the 2 layer, so the wear resistance is good. Flame hardened cast iron can also be directly welded.CMC-E67NEspecially suitable for cast steel hardfaced making render buffer layer, cracking of welding, welding reconstruction.CMC-E65NCmc-e65n low temperature welding, low expansion coefficient, slight hardening, especially suitable for cast iron cast steel (fc.fcd) steel hardfaced making render buffer layer.CMC-E61NSuitable for welding all kinds of cast iron, alloy cast iron, steel and cast iron joint, nickel and its alloy, or welding of water proof die castings.WE777 special cast iron welding rodSuitable for the full range of cold welding welding, welding cast iron base material can almost all, and it is easy to achieve cast iron and carbon steel dissimilar metal welding, such as solving matrix fracture, crack, wear, hole filling defects after welding can be machined, many applications in the engine casing, cylinder head, casting machine, gear base the tooth of iron castings.
Q:Hand welding electrodes 3.2 and 4 which are more commonly used?
Hand welding electrodes 3.2 and 4 are more commonly used.
