Today wood bandsaw blades are almost always tipped using automatic tipping equipment. The two most imporant methods are resistance welding and plasma welding. With both methods, the steel must always be tempered immediately after ipping. Tempering can be carried out in various ways, including using high-frequency induction, passing it through the passing it through the plasma arc for a second time, or using a gas jet depending on the type of machine, price range, etc.
Automatic tipping machines that operate on resistance welding principle heat up the steel in the tooth tip and a small bit of wear-resistant material using a low voltage current with high intensity. Both materials begin to glow almost immediately, and are then pressed togehter and thus welded. The high temperature softens the materials without melting them, which means that a newly tipped tooth point is never contaminated by the underlying steel
