Cladding and Joining
 
 
 
Use the HIP process for cladding and joining parts - expect stronger bonding, improved density of sprayed coatings and welds, plus reductions in net component costs



 
 
 
In today’s market, re-casting components is not financially viable. HIP’ing may be used to recover castings with microporosity and voids.

 
 
 
HIP achieves zero porosity in PM parts and leads to enhanced mechanical properties, cost reductions and enhanced design possibilities.

 
 
 
Cladding and Joining

Solid state diffusion bonding or cladding of different materials is accompished through Hot Isostatic Pressing, without changing the properties of either material. Solid/solid, powder/solid and powder/powder combinations are possible. Cladding parts with thick or thin layers can be acheived - high cost materials can be utilised sparingly to minimise total costs.

Where conventional brazing does not provide sufficient integrety, HIP (in conjunction with encapsulation techniques) can be used to join together two incompatable materials, producing complete bonding with no porosity.

HIP brazing significantly broadens the range of possible material combinations, allowing the designer to combine very different material properties in close proximity within a small space.

The benefits of clad or joined products are:

  • Improved density of sprayed coatings and welded joints.
  • Elimination of porosity at the bonding interface of materials.
  • Reduced component cost.
  • Achievement of component properties which are not achievable with a single material.
  • Improved density of sprayed coatings and welded joints.
