Cast Iron Repair
The repair of broken or cracked castings or cast steel always holds a great challenge, since cast iron can only be welded to a certain extent. Therefore, ARNOLD offers a cold process, the cast iron repair. This avoids thermal stress problems, as for example through welding and preserves the original alignment.
The proven 80-year-old cast iron repair, also known as interlocking technology, can be performed directly on a component on-site. The component does not have to be dismounted for repair.
