Successful orbital welding is also dependent upon using high quality tubing material. Typically only 316L stainless steel tubing (not pipe) and fittings are used for automatic orbital welding and are obtained from a number of specialty manufacturers. The weld quality depends upon having a reasonably clean source of Argon for backing and ...
Vibration can be achieved either through linear vibration welding, which uses a one dimensional back and forth motion, or orbital vibration welding which moves the pieces in small orbits relative to each other. Linear vibration welding is more common due to simpler and relatively cheaper machinery required.

Radio-frequency welding, also known as dielectric welding and high-frequency welding, is a plastic welding process that utilizes high-frequency electric fields to induce heating and melting of thermoplastic base materials. [1] The electric field is applied by a pair of electrodes after the parts being joined are clamped together.
Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
On November 17, 2014 ATK stated that its due-diligence assessment of its merger with Orbital Sciences undertaken in response to the failure of Orbital's Antares rocket found that the transaction remained in the best interest of its shareholders. Both firms rescheduled shareholder votes on the merger from December 9, 2014 to January 27, 2015. [10]
The Welding Journal en Español has a circulation of 10,000 printed copies and 40,000 digital copies. Along with this publication, the Welding Journal em Português is a magazine distributed in Brazil to coincide with the Brazil Welding Show that takes place every two years in São Paulo, Brazil.
