关于锅筒、集箱管孔修补方法的探讨

Study on the Pipe-hole Repair Method of Boiler Drum &Collecting Header

工业锅炉制造中管孔加工量约占锅筒集箱工作量的40%,操作者失误即可能造成该锅筒报废。我们试图通过补焊的方法找到挽救的方法。

The processing capacity of the holes in pipe is about 40% of the processing capacity of the boiler drum and collecting header in boiler fabrication .The boiler drum will be discarded because of operating error. This paper try to solve it by repair welding.
