Discover Egan: Orbital Welding

Tuesday, June 14th, 2022

Orbital welding: a complex process that can be broken down quite simply. 


Also known as high-purity pipe welding, this specialized, highly automated welding process consists  of an arc that rotates 360 degrees around a static piece, whether that be pipe or another object, resulting as one continuous weld. By using this process, a uniform weld is created around pipe and tube, which would be difficult to achieve with a traditional, manual welding  technique. With the use of a computer automated welder, these welds are created in a uniform manner, resulting in them being repeatable and of higher quality with little to no room for error. 


  1. Error reduction: This automated welding decreases the potential for operator error, since the weld is completed based on the data entered in the computer. Once a weld coupon is approved, it can be easily replicated without further input or changing settings.
  2. Higher weld quality: Using this equipment creates better quality welds while meeting the strict requirements of certain industries like pharmaceuticals, which require extremely clean/pure piping.
  3. Standards and Practices: Certain processes require a high degree of weld uniformity and purity in order to meet the required standard and pass inspection. 
  4. Use of labor: With the machine doing the majority of the work, manual labor is reduced and projects are completed quicker.
  5. Use in many settings: Sometimes welds need to be completed in confined spaces or high-risk environments. When utilizing orbital welding equipment, risk is reduced for operators.
