Furnace Brazing of Cast Iron Flywheel for a Manufacturing Application

Step by Step Report Presentation

A customer in the manufacturing industry needed cracks repaired on a large cast iron flywheel. At LOCK-N-STITCH Inc. we are true metal craftsmen and have over 10 year's furnace brazing experience, which was the process necessary to repair this damaged 5' diameter flywheel. The damaged area was ground out to prepare it for the furnace brazing application; this also required the use of an oxy-acetylene torch and bronze rod. For this process our oven had to reach a temperature of 1000°F followed by a slow cool down period so the metal would not be distorted.

After the completion of the furnace blazing we hand finished and painted the flywheel to the customer's specifications. At LOCK-N-STITCH Inc. we can furnace braze cast iron products of all shapes and sizes; this large cast iron flywheel is just one example of our many in-house capabilities.
