QUALITY COMPARISON

The overwhelming productivity of high value material 0% defective rate reduce the operation procedure to maximum.
Groove procedure reduced! Welding procedure reduced.

Conventional Method

Conventional-Method-1
  • Inevitable Under cut & Under fill
  • Extra TIG process needed for preventing Under cut & Under fill
  • Internal stress rises
  • Productivity decreased
