 Product information > Invergter SEAM automatic welding device |
 |
| Seam welding device on STRAKE for MEMBRANE 96-2 LNG transport tank construction. |
 |
 |
- High welding quality by using inverter control rather than existing SCR control
- By using welding cycle time adjustment, welding speed is increased by 20%
- 20% lighter weight for better portability
- High cooling function using cooling chiller |
