METHOD OF CLADDING AND FUSION WELDING OF SUPERALLOYS USING COMPOSITE FILLER POWDER |
摘要 |
The present concept is a method of cladding and fusion welding of superalloys and includes the steps of firstly application of a composite filler powder that consists of 5-50% by weight brazing powder which includes melting point depressants, and 50-95% by weight high temperature welding powder, to a superalloy base material. Secondly there is simultaneous heating of the base material and the composite filler powder by a welding heat source that is movable relative to the base material. There is heating to a temperature that will fully melt the brazing powder and at least partially melt the high temperature welding powder and also melt a surface layer of the base material, thereby forming a weld pool. Thirdly upon solidification and cooling of the weld pool, there is coalescence between the weld bead and the base material. |
