关于厚大铸铁件补焊工艺的研究

Research on the Repair Welding of Thick Casting

采用镍基和铁基铸铁焊条补焊厚大铸铁件时，熔滴经常难以附着在母材上。对其原因进行了分析，并通过工艺措施解决了这一问题。

When the thick castings were repaired by welding,the molten drops from the nickelbase electrode were often hard to adhere to the base metal.The paper researched the reasen and put forward some methods to solve the problem.
