FAQ

E9015-B9 is a welding rod for which steel is welded
Should be chromium, molybdenum, heat-resistant steel welding rod, E9015 means the meaning and structure of steel welding rod means the same significance, B9 is CrMo chemical composition code.s
Can 50Mn2 casting be welded with 507 electrodes?
1, the tensile strength of 50Mn2 (b/MPa): 930.2, welding with 507 electrodes is not possible, the intensity difference is too great.3, you can also choose J807 or J 907.4, welding is quick cooling.s
How are the electrodes made up?
The electrode composition is divided into two parts, metal core and coating (coating). It is composed of manganese, silicon, chromium, nickel, iron alloy, organic substance and so on.Core: generally use low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other ingredients.Coating: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.).s
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.s
What are the requirements of steel structure for electrode?
E43 series welding rod for common steel structure Q235Q345 material of steel to use E50 series welding rodWelding between Q235 and Q345 steels requires the use of E43 series electrodess
What is the difference between A302 stainless steel electrode and A402 stainless steel electrode?
A402 stainless steel welding rod can weld 304 stainless steel, but it is relatively wasteful. 304 stainless steel with A102, A107, A132, A137 and other stainless steel welding electrodes can be welded.A402 stainless steel electrode:A402 is Cr26Ni21 pure austenitic stainless steel electrode with titanium calcium coating, and has good welding performance.Use: for the same type of heat-resistant stainless steel under high temperature welding, can also be used for hardening of the large steel (such as Cr5Mo, Cr9Mo, Cr13, Cr28 etc.) and the welding of dissimilar steel.s
There are several welding electrodes in manual arc welding
There are several kinds of welding electrodes for manual arc welding:1, E4303:E means welding rod, 43 means the tensile strength of deposited metal 430MPa, 0, indicating that welding electrode is suitable for metal position welding, 03 means welding current type for AC or DC zone reverse, and the coating is titanium2, E5015, E means welding rod, 50 means the tensile strength of deposited metal 500MPa, 1, indicating that welding electrode applies to all position welding, 15 means that the electrode is low hydrogen sodium type leather, DC reverse.3, J422, J said electrode for structural steel welding rod, 42, said weld metal tensile strength 420MPa, 2, said electrode for titanium calcium type leather, AC and DC positive and negative connection4, J507 and J indicate that the electrode is the structural steel welding rod, and the 50 represents the tensile strength of the weld metal 500MPa, and 7 indicates that the electrode is low hydrogen and sodium type and the skin is directly connected with the reverse.s
What are the functions of E506 structural steel welding rod, which material is suitable for processing?
You say E506 structural steel welding rod, the correct welding rod brand should be written in E5016 or J506, the former model, and the latter is the brand.E5016 welding rod is a kind of alkali and direct current welding electrode. It is mainly used for basic welding rod which is not used by DC welding machine and welding with AC welder. The material used is the same as J507, and is used for 16Mn (Q345) grade steel.When welding the electrode, the process performance is worse than that of the acid welding rod, that is, spatter is bigger and weld formation is poor. But the metallurgical properties are better, that is, the anti - parathion of welding rod is harmful, and the welding seam has strong anti - crack ability, so it is used in welding of important welding seam. However, this kind of electrode tends to be larger than the direct current alkaline electrode (E5015 or J507), so it is seldom used in welding seams (e.g. pressure vessels) that require inspection.s
