Definitions
- the current repair method is to weld patches onto the cracked area, but it helps only temporarily as repair welding impairs the properties of the surrounding ma ⁇ teria.! and causes distortions due to non-uniform heat ⁇ ing, Consequently, the belt must be discarded and re ⁇ placed, which limits the lifetime of the belt.
