Final answer:
A band saw blade with HSS welded to a carbon steel body is called a bi-metal blade, offering superior wear resistance and flexibility for cutting tough materials.
Step-by-step explanation:
The type of band saw blade that has HSS (High-Speed Steel) welded to a carbon steel body is often referred to as a bi-metal blade. These blades are designed for improved performance and longer life than blades made from a single material. The HSS is welded to the teeth of the blade, providing high resistance to wear and heat, making it suitable for cutting tougher materials like metals. The carbon steel body provides flexibility, which helps prevent the blade from breaking under strain.
Bi-metal blades are a good choice for high-production environments where they may be used to cut a variety of materials. The superior wear resistance of HSS allows these blades to maintain a sharp edge for more cuts before they need to be replaced or resharpened.
