FIELD: repair by welding, applicable for repair of shrouded rollers of secondary cooling zone of continuous casting machines, as well as of other shrouded parts of metallurgical and rolling equipment. SUBSTANCE: repair is accomplished by elimination of defects, preheating and concurrent heating, welding-on of rings by martensite-class material with subsequent heat and mechanical treatment; welding-on is performed by material with equivalent content of carbon Ce= 0,4-2,0%, relation between Ce and thickness of built-up layer being Ce/b=0.08 to 2.2. EFFECT: facilitated procedure. 1 dwg , 1 tbl
