Cladding
Weld Cladding as
Material and Surface Protection
For components in
› Waste-to-energy plants
› Biomass plants
› Coal and gas boilers
› Circulating-bed boilers
› Chemical plants
Ni-based weld cladding for corrosion protection:
› Alloy 622
› Alloy 625
› Alloy 59
› Alloy 686
Weld cladding for erosion protection:
› Use of welding consumables with high chromium content and filler metals for matching base materials.
Single-Tube Cladding
› Circumferential cladding / spiral cladding of headers & single tubes (e.g. for superheater coils)
› Cladding lengths: max. 14 meters per tube
› Layer thicknesses: 1 mm to ≥2 mm
› Welding process: E-pulse or CMT process (cold metal transfer)
Membranewall Cladding
› Cladding on ready-to-install membrane wall panels
› Layer thicknesses: >1 mm to ≥2 mm
› Cladding lengths: max. 9 m per panel
› Welding method: Two-pass CMT technique with a 50% overlap
On-Site Cladding
› Maintaining plant availability and cost-effectiveness
› On-site weld cladding for high-risk erosion and corrosion zones
› Initial cladding as a preventive measure
› Repair & Re-Cladding
› Automated weld cladding / manual cladding (all welding positions possible)
› Multi-shift operations available, including weekends
