X-Ray Testing
Precisionvast employs advanced X-ray testing to ensure internal integrity and flawlessness of our investment castings. This non-destructive method provides deep insights into the internal structure, identifying hidden defects to maintain our high-quality standards
X-Ray Testing of Investment Casting
X-ray testing in casting is a non-destructive examination method that uses X-rays to view the internal structure of castings. This technique is crucial for identifying hidden flaws such as cracks, voids, or inclusions within a casting that are not visible to the naked eye. The necessity of X-ray testing stems from its ability to ensure the structural integrity and quality of castings, which is vital in applications where failure can have severe consequences. By detecting these internal imperfections, X-ray testing helps in maintaining the safety, reliability, and performance standards of the final cast products
The main defects in castings that can be detected by common X-rays:
- Porosity: Caused by trapped gas or shrinkage during solidification.
- Inclusions: Foreign materials embedded due to improper material handling or contamination.
- Cracks: Due to thermal stress, rapid cooling, or material brittleness.
- Cold Shuts: Occur when two metal streams solidify before merging completely.
- Shrinkage Cavities: Formed when the metal contracts on cooling and doesn’t have enough material to fill the mold.
- Misruns: Result from inadequate metal fluidity, failing to fill the mold.
- Slag Inclusions: Caused by non-metallic slag material entrapped in the casting.
- Hot Tears: Develop due to inhomogeneous temperature distribution during solidification.
- Sand Burn-On: Sand from the mold sticking to the casting surface.
- Flash or Burrs: Excess material formed at the mold’s parting line due to misalignment or wear.
Precisionvast foundries are fully capable of providing NDT testing, including magnetic particle, X-ray and other testing. Please contact us if your castings have such requirements!
