Orbital Welding for Sanitary Piping

Orbital welding in Sanitary application is extension to tungsten inert gas (TIG/TGAW) welding. This type of welding is default in piping, which the application demands Sanitary or super clean application, where cleaning is done with CIP/SIP.

The pharmaceutical industry currently uses orbital GTAW/TIG welding almost exclusively. This produces welds of high quality with very low rejection percentages; these joints possess high strength, high purity meta, and good surface finish.

Orbital welding is the controlled rotation of components within a fixed support, while an adjustable, non-consumable tungsten electrode attached to a guide moves (or “orbits”) the joint. The electrode, the arc, the area surrounding the weld, and tube interior are protected by a shield of inert gas—usually argon—with a purity of 99.995/99.999% 

Virtually all the metal alloys employed in the pipeline fabrication sector can be welded and since the process is carried out in an inert atmosphere it produces results that are extremely clean, oxide free and without spatter

Its completely automated process and hence needed precision when preparing the face and edges before welding.
