Core Processes Overview
Bi-Metal Band Saw Blade Welding & Heat Treatment are the core processes in the manufacturing of bi-metal band saw blades, which directly determine the structural strength and service life of the product.
Structural Strength Guarantee
High-precision welding ensures reliable bonding of bi-metal materials, avoiding delamination during cutting.
Mechanical Property Balance
Heat treatment optimizes tooth tip hardness and back material toughness for sawing conditions.
Service Life Extension
Professional welding & heat treatment processes double the service life of bi-metal band saw blades.
Welding & Heat Treatment Details
In the welding link, the suitable welding surface is first prepared through the edge trimming process, and then electron beam welding or laser welding technology is used to achieve high-precision composite welding of high-speed steel wire and alloy steel strip, which is the key to ensuring the bonding strength of the bi-metal. In the heat treatment link, the spheroidizing annealing process is first used to spheroidize the carbides in the weld seam and base material to adapt to the subsequent cold working; then through the integrated quenching and tempering process, the metallographic structure of the saw blade is regulated, the hardness of the tooth tip and the toughness of the back material are balanced, and the product is endowed with the core mechanical properties suitable for sawing conditions. This is the core value of Bi-Metal Band Saw Blade Welding & Heat Treatment.
High-Precision Welding
Edge trimming + electron beam/laser welding ensures bi-metal bonding strength of high-speed steel & alloy steel.
Spheroidizing Annealing
Spheroidizes carbides in weld & base material to adapt to subsequent cold working processes.
Quenching & Tempering
Regulates metallographic structure to balance tooth hardness and back toughness for optimal sawing performance.
