CladFuse process

CladFuseTM weld overlay process

CladFuse is an effective and commercially viable protection for boiler components against base material thinning caused by corrosion and erosion. It provides long term protection for membrane wall and tubes, avoiding and preventing future costly unplanned outages and replacements.

Key features of the CladFuseTM weld overlay process are:

  • Automated weld overlay on new or worn carbon steel tubes
  • Vertical down and overhead welding positions
  • Predetermined weld bead pattern
  • 50% overlap of beads
  • Weld overlay thickness > 2mm
  • High material deposition
  • Controllable and consistent parameters
  • Continuity of beads
  • Minimum iron content
