ABSTRACT:
A method of brazing of an outer carbon steel shell to an inner stainless steel shell, in which a stainless steel sheet material of the inner shell is rolled up with an overlap and arranged with a clearance inside the outer shell, braze material is placed in the clearance, walls of the rolled sheet material of the inner shell are forced to the inner surface of the outer shell, longitudinal edges of the sheet material of the inner shell are weld-joined to form the inner shell, air is evacuated from the clearance, and ends of the outer and inner shells are joined by circular vacuum-tight corner welds, one leg of which extends radially and has a length equal to at least one thickness of the inner shell, whereas the length of the other leg, which extends longitudinally, is equal to at least twice the thickness of the wall of the inner shell and said inner and outer shells are brazed in a furnace forming after cooling a bimetallic cylindrical article.
