2. Weld access hole - Wikipedia

   en.wikipedia.org/wiki/Weld_access_hole

   The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.

4. Threaded insert - Wikipedia

   en.wikipedia.org/wiki/Threaded_insert

   TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...

5. Safety wire - Wikipedia

   en.wikipedia.org/wiki/Safety_wire

   A safety wire is used to ensure proper security for a fastener. The wire needed is long enough to reach from a fixed location to a hole in the removable fastener, such as a pin — a clevis fastener, sometimes a linchpin or hitch-pin through a clevis yoke for instance — and the wire pulled back upon itself, parallel to its other end, then twisted, a single end inserted through a fastener ...

6. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   If the welding current is applied too long, the entire spot melts, the material runs out or otherwise fails, and the "weld" becomes a hole. The voltage needed for welding depends on the resistance of the material to be welded, the sheet thickness and desired size of the nugget. When welding a common combination like 1.0 + 1.0 mm sheet steel ...

8. Weld purging - Wikipedia

   en.wikipedia.org/wiki/Weld_purging

   Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.

9. Notch (engineering) - Wikipedia

   en.wikipedia.org/wiki/Notch_(engineering)

   Sharp tipped V-shaped notches are often used in standard fracture toughness testing for ductile materials, polymers and for the characterization of weld strength. The application of such notches for hard-steels is problematic due to sensitivity to grain alignment, which is why torsional testing may be applied for such materials instead.
