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:Can white steel electrode weld cast iron?: White iron welding electrode can be cast iron, but it is recommended to use pig iron welding, because white steel welding rod after welding is easy to crack.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:Can ordinary 422 electrode welding pig iron?: If your "pig iron" refers to white cast iron, then please dispel the concept of welding. If the volume is not too large gray cast iron, the actual method of operation is cast iron hot welding.Equipment: cutting gun, AC welderProcess: welding workpiece positioning, and then open the oxygen preheating heating by gas burners for welding of cast iron by glowing red hot, and then use the 507 electrode welding current. Better heat preservation if the casting sand is used after soldering.

Q:What's the model of lap welding for two grade steel bars?: One or two grade steel is HRB335, 335Mpa. if used does not require structural strength or do not require strength and yield strength, can be used J42 electrode. Otherwise, using J50 electrode. Welding for steel structure, general requirements for the strength of weld metal and base metal electrode. According to the strength of the steel structure. Choose the corresponding strength.Two, two simple introduction of steel bar:That is the new standard name for HRB335 steel, two steel for the old, as a kind of hot rolled ribbed bar. Thread steel in the construction industry, the second class of rebar and grade III thread steel is called in the past, the new standard, the second class of rebar is called HRB335, and the third class of rebar is called HRB400. Widely used in housing, bridges, roads and other civil engineering construction.

Q:What is the difference between stainless steel welding wire and electrode?Such as;1, its welding effect or quality?2, how does it affect your body?3, its price and cost profit?The main topic of attention; he influence on the human body, (I once heard that the stainless steel has a great influence on man's reproductive function, welding of stainless steel welding technology do not know now there is no change?): The stainless steel electrode is welded by a DC welder, and the stainless steel wire is welded by argon arc welding. The welding rod is expensive, but the direct current welder can be used directly. The workpiece is generally used for welding large workpieces or not of good weld quality. Welding wire is cheap, but argon arc welding machine and argon gas arc welding can be used to weld thin plate easily. The welding rod is not easy. The welding seam of argon arc welding is easy to handle and beautiful. The cost of the two is not good, because the use is not the same. Argon is inert gas, there is a certain harm to the human body, not married, give birth to the child's best not to dry, otherwise it will be sterile, if dry, after a period of time in order to have children. The above answer may not be entirely correct, but they are all listening to the master in the workshop and hope to be helpful to you.

Q:When welding, the welding rod sometimes can easily stick to the weldment, and it is not easy to arc. The ignition is also easy to extinguish. Why is that? What happens when this happens?: Small current, or electrode diameter, or line is too thin, or welding power line to catch bad, or electric welding handle wire or wire, catch the bad, look for yourself, if not all of these phenomena is that electric welder secondary coil, and the short circuit between the tie bar

Q:How to keep the welding electrode well?: 1., placed in a dedicated electrode oven, to prevent moisture, 2. categories placed, to prevent confusion of different electrodes

Q:What is bubble welding? What's the difference between a common electrode and an ordinary one?: It should be (gas shielded welding)...... It means gas shielded arc welding! Protect welding with inert gas......

Q:How to use hot 317 welding rod?: R317 is a low alloy steel welding rod with low sodium hydrogen type. It can be welded in all positions by DC reverse welding, and the welding process is good. The weldment should be preheated to 250~300 DEG C before welding and should be treated at 700~740 DEG C after welding.

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: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.: Save good words is two years, do not damp, and if it is relatively high requirements, the use of baking, remove moisture.
