Welding preheating is a critical step in the manufacturing and repair of Tunnel Boring Machine (TBM) components.
Recently, our WTR induction heating system was used for welding preheating of heavy-duty TBM parts, helping the customer achieve uniform temperature distribution before welding and improve overall welding quality.
Compared with traditional flame heating, induction heating provides faster heating speed, more accurate temperature control, and a safer working environment.
Why Use Induction Heating for TBM Welding?
TBM components often involve:
1. Thick steel plates
2. High-strength steel materials
3. Large welding areas
4. Strict welding procedure requirements
Proper welding preheating helps reduce welding stress and minimizes the risk of cracking during fabrication and repair.
Typical Applications
WTR medium frequency induction welding preheating equipment is widely used for:
● TBM cutterhead welding
● Cutter holder welding
● Structural steel fabrication
● Heavy machinery manufacturing
● Railway and infrastructure projects
