2. Weld nut - Wikipedia

   en.wikipedia.org/wiki/Weld_nut

   Retainer weld nuts, also known as bridge weld nuts, have a floating nut retained inside a retainer to compensate for inconsistencies. The retainer is welded to the work piece while the nut is allowed to float. [2] Tube end nuts. Tube end nuts are sized to fit into the end of standard sized tubing, thus creating a threaded tube from standard ...

3. Tube bending - Wikipedia

   en.wikipedia.org/wiki/Tube_bending

   The tube is held in tension by a wiper die to prevent any creasing during stress. A wiper die is usually made of a softer alloy such as aluminum or brass to avoid scratching or damaging the material being bent. Much of the tooling is made of hardened steel or tool steel to maintain and prolong the tool's life.

4. Rotary friction welding - Wikipedia

   en.wikipedia.org/wiki/Rotary_friction_welding

   Friction welded rods of aluminum AA1050 and AISI 304 stainless steel with diameter of 14.8 mm. Rods before and after welding prepared for tensile test. [49] The AISI 304 stainless steel has higher strength than the aluminum alloy. Hence, the formation of flashes was restricted to AA1050 aluminum only. [49]
