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 kind of welding rod should be used for welding cast steel parts?: Ordinary steel welding, according to the general steel strength to choose, most of the structural steel welding rod, according to the strength of the cast steel of different levels, in turn can choose the type of electrode (or model) with J42 * (E43 * *), J50 * (E50 * *), J55 * (E55 * *)... Etc...

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 welding rod is used for the welding of Q345 material?: J503, J502, J507, J506, J507GR and J507RH grade electrodes can be used for welding.Welding hot rolling and normalizing steel, is the main basis for the guarantee of weld metal strength, plasticity and impact toughness and other mechanical properties of base metal and matching of welding thick component, in order to prevent welding crack, can adopt "undermatched" principle, namely the selection of weld metal strength is lower than the base metal electrode. When welding low carbon quenched and tempered steel, the hydrogen should be strictly controlled, so the low hydrogen or ultra low hydrogen electrode should be used. In order to ensure the plasticity, toughness and strength of weld metal, and to improve the crack resistance, the low carbon alloy system should be adopted to reduce the content of sulfur and phosphorus in the weld metal.

Q:Can welding of stainless steel plate and ordinary steel pipe be welded with thj422 welding rod?: No, stainless steel electrodes should be selected.

Q:What's the difference between 507 and 422 electrodes?: Both J422 electrode and J507 electrode are low carbon structural steel electrode, but the tensile strength of them is differentJ422 welding rod metal tensile strength is not less than 42kgf/mm2 (about 420MPa),J507 welding rod metal tensile strength is not less than 50kgf/mm2 (about 500MPa),J422 is a kind of carbon steel welding rod with titanium calcium type coating. AC and DC dual-use, can be carried out in all position welding. With excellent welding performance and good mechanical performance; stable arc, small splash, easy slag removal, and arc easily; better appearance of weld, welding width, wave narrow, thin, thick, easy welding, high efficiency.Application: used for welding low alloy steel structures with lower carbon steel structure and lower strength grade, such as Q235, 09MnV, 09Mn2 and so onJ507 is a carbon steel electrode with low sodium hydrogen type. Direct current reverse welding can be carried out in all position welding. With excellent welding process performance, stable arc, less spatter, easy to remove slag, the deposited metal has excellent mechanical properties and crack resistance, low temperature resistance, good impact toughness.Usage: used for welding of carbon steel and low alloy steel structure important (compression and dynamic), such as 16Mn, 09Mn2Si, 09Mn2V, B, A and marine D, E grade steel, also used for welding carbon steel plate and poor weldability.

Q:What steel electrodes are used (I'm a beginner's welder)?: Oh, many kinds of electrodes, series. Just now, the variety is many, who can help you enumerate one by one, I suggest you read the book yourself, is a beginner welder, more should contact some book knowledge, can save a lot of things

Q:Is the electrode electrically conductive?: See what you use general electrode, metal electrodes are electrically conductive, including welding, argon arc welding, carbon dioxide gas shielded electrode are electrically conductive, but PVC is not conductive electrode, it is plastic, its welding principle and the front is not the same, is used to realize the welding electrode heating and softening the.

Q:What welding electrodes are used to weld 304 stainless steel pressure vessels?: 1, 304 is the United States standard, GB is 0Cr19Ni9, you can choose A102, A107 can, if you don't worry, you can use A302, but the cost is higher, it is better to use A107 welding rod, it's crack performance is better.2, I wish you success.

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:Why is the welding of important structure using alkaline electrode?: Alkaline is a low hydrogen electrode, which can control the hydrogen content in the weld, avoid hydrogen embrittlement and lead to structural failure. Hydrogen embrittlement is the sudden breaking of the weld force
