FAQ

What kind of welding rod should be used for welding cast iron? 506?

There is cast iron welding rod, 506 is medium carbon steel or low alloy steel welding rod

304 generally use A102 welding rod,321 generally use A132 welding rod,Dissimilar steel A302 welding rod,May I ask if 304 can use A132 welding rod? Why?

1, no, in addition to welding and to achieve the parent material and other strong mother, but sometimes need to consider the toughness of the weld zone, with high strength instead of reducing the performance of materials.2, A132 is a kind of Cr19Ni10Nb stainless steel welding rod containing Nb stabilizer. It has excellent intergranular corrosion resistance and good mechanical properties. With excellent welding process and anti porosity property, drug Pinai redness, anti cracking, but the ac-dc.3, 304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. 304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.

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.

What is the difference between electrode type and brand?

It doesn't make any difference. Just use it. It's mainly the function of welding machine!

Electrode: 506--J48-56 junction, Tianjin Bridge Welding Materials Group Co. Ltd. production. Is it possible to use an AC welder?

J506 welding rod, using DC welder, AC welder can.

What are the welding electrodes?

Not a single electrode metal material, which is composed of a metal core and coating. The electrodes of each model are different in composition.The electrode consists of two cores 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 electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire.When welding, welding core has two functions:One is to conduct welding current, which generates electric arc and converts electric energy into heat energy;The two is the core melting as the formation of the weld filler metal and liquid base metal fusion.

Requirements for welding electrodes for temperature and humidity

Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.

What's the type of electrode used for 304 stainless steel?

Can I use this electrode, with fierce wire, 304 special, different, and the common shrew thread more than 30, close to forty yuan a catty, you can call the specific delivery time stainless steel manufacturers, 304 special account on the line
