Orbital Fabrications specialises in High Purity Welding, this technique is used across various industries, namely within laboratories, universities and in semiconductor, pharmaceutical and aerospace.

The process involves the welding of tubes to transmit special gases. It is essential that the inside of the weld is exceptionally clean so that the gasses are transmitted without contamination. Our High Purity Welding is completed in the controlled environment of an Orbital Cleanroom which prevents any nuisance substances from accessing the weld.

The sterile environment is so essential as any contaminants within the weld can lead to the eventual failure of the entire system. A dirty weld which has been accessed by corrosive or oxidising contaminants or other impurities compromises the integrity of the tubing and in turn the entire component.

Why the Semi-Conductor Industry Needs High Purity Welding

High Purity Welding is particularly useful within the semi-conductor industry. Semi-conductor fabrication involves the use of stainless process lines in the transportation of gases which, if leaked, can be highly toxic, corrosive, and flammable.

Due to the dangerous nature of the gasses, it is imperative that the completed weld of the tubes boasts high integrity and reliability. Where dangerous gasses are involved, the weld must pass safety testing procedures. The transferred gases must pass through without accumulating particulates, moisture, or other contaminants. For work within this industry, the inner weld must be incredibly clean and smooth to ensure the quality of the gasses passing through is not compromised.

Key Considerations in High Purity Welding

  • High Purity Welding should ensure accurate, strong welds that are deficient of any defects such as voids, cracks, pits or discoloration, outside and inside the tube.
  • It is essential to ensure that the process enables traceability and repeatability.
  • The welding process must take place in a highly controlled environment such as our Class 6 cleanroom ensuring that the gasses passing through the tubes are clear of contaminants.
  • The process must be undertaken by highly skilled engineers who are experienced in High Purity Welding.
