Cast 308 pure nickel cast iron welding electrode. What shall be used for welding?
Usually used for welding of grey cast iron is better than the ordinary structural steel electrode or stainless steel electrode strength, generally used for welding cast iron of ordinary civilian, industrial equipment if it is real iron, cast iron material is unknown, strength demanding case suggested that welding using WE777 special cast iron electrodeApplication of 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.
Welded stainless steel.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, the welding core has two functions: one is the conduction of the welding current, arc energy converted into heat, two cores melting as the formation of the weld filler metal and liquid base metal fusion.
The iron parts to be machined after welding.No machining is OK, but the cost is high.
