CLADDING & WELDOVERLAY:

Cladding & Weld Overlay

Cladding & Weld Overlay provides protection against corrosion and wear for process and pipeline equipment. Weld overlay can be applied to extend the service life of new parts, or refurbish parts that have corroded orworn surfaces Ritinox Integrated and advanced welding technologies provides effective welding solutions for:

  • Oil&Gas Industries

 

  • Sub-Sea Applications

 

  • Petrochemicals&Refineries

TYPES OF CLADDING PROCESS: Weld Overlay:Weld overlay is a fusion welding technique used to deposit weld metal on to component to achieve the desired dimensionsor properties replacing lost material or providing a wear or corrosion resistance surface.

Explosion Bond :Explosion bonding is a process of bonding two dissimilar materials with the help of pressure and heat produced by explosion. The explosive material is spread on the material tobe cladded which is kept on top of the base material. On ignition of the explosive, resultant thrust bonds the clad plate onthe base plate kept underneath. Various combination of clad plate and base plate thickness can be bonded, depending on the job requirements.

QUALITY CONTROL SYSTEM:

 

FORClad Fabrication:

  • Internal Ultrasonic Testing of plate before fabrication.

  • Cleaning of clad surface after forming of head before heat treatment if required

  • Heat treatment in electric or gas fired furnace in controlled atmosphere to avoid any Contamination and to prevent oxidation of surfaces.

  • Ultrasonic testing of formed components forde-bond check between clad and basematerial.

  • NDE testing, Radiography, Hydrotest & PMI check

FORWeld Overlayed Items:

  • Prior to overlay, grinding, cleaning and dye penetrant testing of surface of basematerial tobe overlayed

  • Overlaying as per qualified welding procedure.

  • Dye penetrant testing ofoverlayed surfaces.

  • Ultrasonic Testing from opposite surface for checking un-fused/disbond areas.
