目前在铸铁冷焊中,非加工面的焊补大约占60%左右。一般铸铁冷焊常用的焊条有:镍基铸铁焊条;铜钢、铜不锈钢铸铁焊条;高钒铸铁焊条;氧化铁型铸铁焊条。但是由于以上焊条因价格贵、资源较缺,制造困难等方面原因,应用受到限制,因此,我们试制了一种新的用于非加工面的铸铁焊条——纯铁芯铸铁焊条。

Currently in the cast iron cold welding, non-processing surface welding repair accounts for about 60%. Common cast iron welding commonly used electrodes are: nickel-based cast iron welding rod; copper, copper stainless steel cast iron electrodes; high vanadium cast iron electrodes; iron oxide cast iron electrodes. However, due to the expensive electrode, lack of resources, manufacturing difficulties and other reasons, the application is limited, therefore, we trial a new cast iron electrode for non-processing surface - pure iron cast iron electrode.
