If a bandsaw blade breaks, it can be brazed or welded. But check for the cause. The most common causes include: 1) misalignment or adjustment of the guides, 2) either forcing or twisting a wide blade around a curve, 3) feeding in the work too fast, 4) dull teeth or not enough tooth set, 5) excessive tightening of blade, 6) top guide set too high above work being cut, 7) using a blade with improperly finished braze or weld, and 8) continuously running the blade when it is not used for cutting.
