Butt Weld Breakage

To determine if the band broke at the weld, inspect the sides at the fracture to see if there are grind markings from the weld finishing process.

Probable Cause :

1. Band saw is a wood cutting saw. Wood cutting saws will run an average of 800-3500 surface feet a min (sfm). Metal cutting saws are designed to run from 40-300 sfm. When running a Bi-Metal Blades at high speeds like a wood machine runs breaks can occur easily. These band saws designed for wood working run at high speeds and are running a carbon blade that has more flex.
2. Any of  the factors below can also cause body breaks and  butt weld breaks.
