What kind of welding rod are used for welding cast iron and carbon steel?
Welding of cast iron with nickel copper electrode, such as 508, oxygen - acetylene welding (preferably heating welding, after welding, thermal insulation, prevent and crack white) with special cast iron electrode.Welding low carbon carbon steel with ordinary carbon steel electrode, usually welding.
Welding of cast iron and carbon steel:Welding of cast iron with nickel copper electrode, such as 508, oxygen - acetylene welding (preferably heating welding, after welding, thermal insulation, prevent and crack white) with special cast iron electrode. Can also choose Z308 (cast 308) nickel based welding electrode. When welding can not be cold, the heating temperature of gray cast iron should be 600-650 degrees Celsius. After welding must be insulated in order to ensure the performance of welded joints.
The cast iron needs the cast iron electrode or the stainless steel electrode, of course, these two kinds of welding electrodes need high temperature drying before welding. Carbon steel is made with ordinary electrodes. Welding electrodes are generally used in accordance with welding procedures.
