铸铁焊接自从创始以来,约有七十年历史。在此期间,曾作过许多铸铁焊接的试验,积累了丰富的经验。过去的实践证明了铸铁焊接是经济合理的,因为花很小的代价和很短的时间就能修复损坏的另件和修补作废的铸件。其次,在过去这段时间内,亦明确了铸铁焊接在工业中的主要应用部门为:1.制造新设备的铸造工厂和机械装配车间——采用铸铁焊接方法修 Cast iron welding since its inception, about 70 years of history. In the meantime, he has done a lot of cast iron welding tests and has accumulated rich experience. Past practice has proved that cast iron welding is economically justifiable because it can repair damaged parts and repair obsolete castings at a fraction of the cost and in a fraction of the time. Secondly, during the past few years, it has been clarified that the main applications of cast iron welding in the industry are as follows: 1.
