Category: Friction welding machines
Application, field: Machine parts

Textile machinery parts
Material: Carbon steel

S45C×SS400×STKM38
Bonding dimensions: φ152.4×t3.2
Conventional technique: Caulking
Purpose: Improved quality

Reduced cost

Reduced weight

Issues to be resolved

Integrated forged part shrink fitted to pipe and caulked with parallel pin
- Joint machining using thick pipe
- Heavy product weight
- Defects at shrink fitting process

Adoption merits

- Reduced blank cost by machining workpieces separately (forging eliminated)
- Bonded parts have butt weld shape
- Weight reduced with use of thin pipe
- Lower defect rate
