2. Rotary friction welding - Wikipedia

   en.wikipedia.org/wiki/Rotary_friction_welding

   Example of Rotary friction welding weldability table. [31] This is the basic table because the currently known list of materials is much larger and the name alloy systems are classified by a number system ( ANSI ) or by names indicating their main alloying constituents ( DIN and ISO ).

3. Rotary table - Wikipedia

   en.wikipedia.org/wiki/Rotary_table

   10 inch, manual rotary table. A rotary table is a precision work positioning device used in metalworking. It enables the operator to drill or cut work at exact intervals around a fixed (usually horizontal or vertical) axis. Some rotary tables allow the use of index plates for indexing operations, and some can also be fitted with dividing plates ...

4. Friction welding - Wikipedia

   en.wikipedia.org/wiki/Friction_welding

   Some applications and patents connected with friction welding dates back to the turn of the 20th century, [3] and rotary friction welding is the oldest of the methods. [4] W. Richter patented the method of linear friction welding (LFW) process in 1924 [ 5 ] in England and 1929 [ 5 ] in the Weimar Republic .

5. Rotary table (drilling rig) - Wikipedia

   en.wikipedia.org/wiki/Rotary_table_(drilling_rig)

   A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).

6. Orbital welding - Wikipedia

   en.wikipedia.org/wiki/Orbital_welding

   Orbital welding is a specialized area of welding whereby the arc is rotated mechanically through 360° (180 degrees in double up welding) around a static workpiece, an object such as a pipe, in a continuous process.

7. Friction stir welding - Wikipedia

   Close-up view of a friction stir weld tack tool. The bulkhead and nosecone of the Orion spacecraft are joined using friction stir welding. Joint designs. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
