Orbital Welding
Orbital welding was first used in the 1960s when the aerospace industry recognized the need for a superior joining technique for aerospace hydraulic lines. A mechanism was developed in which the arc from a tungsten electrode was rotated around the tubing weld joint. The arc welding current was regulated with a control system thus automating the entire process. The result was a more precise and reliable method than the manual welding method it replaced.
Modern day orbital welding systems like the one used by Pharmalab, offer computer control where welding parameters for a variety of applications can be stored in memory and called up when needed for a specific project/product. The skills of a certified welder are thus built into the welding system, producing enormous numbers of identical welds and leaving significantly less room for error or defects.
