Pool oscillations and cast variations - penetration control for orbital tig welding of austenitic stainless steel tubing. [PDF]
, 1997 Pool oscillations in tungsten inert gas welding pools have been used in a closed- loop control system for orbital welding of ultra high purity tubing, determining a target level of penetration by altering the welding current in real-time.
