Welded blades are safer than abrasive blades (see this article on the dangers of abrasive blades), but they’re still dangerous. That’s because the welds holding the cutting segments can overheat – usually from long periods of cutting or from cutting metal – then soften and break. If these welds break during cutting, then the segments can fly off and injure or even kill the saw operator.
To eliminate this hazard, you should use solid steel blades without welds, like the Ductile Iron Safety Blade. These blades may bend but, because they’re made of solid metal, won’t break, increasing your safety. See the video above for proof.
