Abstract

This practical research work has described the procedure for repairing three columns of a ski lift. During the long period of exploitation, more than 40 years, these columns were corroded and seriously damaged. Corrosion leads to thinning of the column wall or even complete perforation of it (formation of cracks). After the determination of the problem, it was decided to undertake measures to solve this problem and put the ski lift in normal function. It was concluded that three columns must be immediately repaired. So, it was prescribed technology for repairing by welding The plan for repairing consists of the following phases: Cutting off damaged segments and embedding new segments from the same material and thickness. Additionally strengthening of columns by two half segments of pipes screw-up and welded for columns. Prepared segments were welded for columns using manual metal arc welding process special attention was paid to protecting columns from demolition during the cutting of corroded parts of columns. The same filler materials were used in this case too. The repair was successfully performed, and the ski lift was put into exploitation.
