The main components of every orbital welding system are the power supply with integrated computer control, the welding head and, where required, a wire feed mechanism. Welding of certain sizes and material types will also require the use of a water/coolant system. There are a large number of factors that can have an influence on the welding result.
The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle in the heart..

A ring bolt is an eye bolt with a captive ring passing through it. [1] The loose ring is articulated, such that it can rotate in at least one axis, and can thus reduce bending forces on the bolt when loaded and will present the minimum obstruction when "flat".
Inventor A. Graham demonstrated, on welding pipes with a diameter of 152.4 mm, a method that uses radial friction welding with an intermediate ring for connecting long pipes, [9] [10] at long last succeeding after some attempts occurred in 1975, [11] and after scientists in Leningrad theorized on the idea in newspapers.

The welding of metal bellows is a microscopic welding process, typically performed under laboratory conditions at high magnification. Hydroformed bellows are produced by forcing a metal tube to expand under hydraulic pressure inside a bellows-shaped mold, and assume the convoluted shape of the mold.
