Assembly Methods
Brazing
A common method using filler metal with lower melting point than carbide and base material. Buttons are positioned on the tool, then brazing material is heated to melt and bond carbide to the tool substrate.
Press-Fit
Precisely manufactured buttons fit into corresponding cavities on the tool substrate. Buttons are press-fitted using hydraulic presses or mechanized equipment for a tight, secure bond.
Adhesive Bonding
Specialized adhesives applied to button or substrate, then positioned and pressed into place. Adhesive cures to form a strong bond securing the carbide.
Mechanical Fastening
Buttons attached using screws, bolts, or rivets through pre-drilled holes in both carbide buttons and tool substrate.
Sintering
Buttons sintered directly onto tool substrate during manufacturing using heat and pressure to create a strong metallurgical bond at molecular level.
Welding
Melting carbide and/or substrate material along joint area, allowing solidification to create a fused bond between materials.
The selection of assembly method depends on tool type, button design, material compatibility, and required bond strength and durability. Each method offers distinct advantages in cost, efficiency, and application-specific requirements.
Applications
Coal mining, construction drilling, excavation, road milling and planing, and stone crushing machine rock breaking applications.
