All castings manufactured by Ticronik must be without cracks, cissing, foreign inclusions and other types of defects that are reducing operational reliability and considerably worsen salable condition of our products.
- Single shells with an area less then 0.5 sm2 and depth with less then 10% of overall casting body thickness, and located not closer then 15 mm from the edge of the foundry-, and overall shells area must be less then 3% of all visible casting surface
- Mappings - long-sweep along their perimeter toward casting surface with overall area less then 10 % of visible part, and depths less then 5 % of wall thickness
– Any defects which depths do not exceed 80 % of stock for machining
– Scabs, shells on landing surface area up to 1% from overall area of this surface and with depths less then 20 % from part’s body thickness
- Shells of any dimensions (only if performance attributes are maintained after correction) – welding method with special solder
- Cracks and solder joints that do not weaken net section. 20%.(welding)
- Mappings with overall area less then 15% from visible surface area and depth that do not exceed 20% of wall thickness (facing welding method)
- Bending, distortion that exceeds deflection particularly indicated by drawings
- Shells and cracks on the friction surface (with total length less then 5% of visible surface), scabs with overall area less then 1% of friction surface area and at depths less then 1/3 of part’s body thickness. (Welding method where preliminary cuttings are made until healthy metal is exposed)
- Local sporadic defects (shells, clogs) on landing surfaces with area up to 2% of total area of the surface.
