大型铸铁件导轨缺陷的热焊补方法

Welding Repairing Method of Defects of Cast Iron Guides

详细叙述了大型铸铁导轨缺陷的热焊补方法,从不同角度考虑选取了铸件的焊补工艺。用此工艺焊补铸件,焊补区 域与基体间没有明显的熔合线,无渣孔、气孔等缺陷。

The hot welding repairing method of defects of heavy cast iron guides was described in de-tail.Considering from different angles,the welding process was chosen.By using this process to repair castings,there is no obvious separating line,no slag inclusion and gas hole between the welding zone and base metal.
