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.
The weld time in this process is between 1 and 6 milliseconds. Capacitor discharge stud welding with the latest equipment can create a weld without burn-through showing on the opposite side of very thin metals. CD stud welding is often used for smaller diameter studs and pins, as well as on non-standard materials and for accuracy.
The channel can be a hot-rolled or a cold-formed steel shape in which a T-shape screw is placed in order to transfer the load to the base material. Headed stud: consist of a steel plate with headed studs welded on (see also threaded rod). Threaded sleeves: consist of a tube with an internal thread which is anchored back into the concrete.

Butt welding is a commonly used technique in welding that can either be automated or done by hand on steel pieces. [1] Butt welding can also be done with brazing for copper pieces. It is used to attach two pieces of metal together such as pipe, framework in factories, and also flanges. [1]

Tab base nuts are designed for spot welding on flat workpieces. They have a locating boss around the threads to locate it in a pilot hole. [1] Hex & square nuts. These nuts are very similar to standard square or hex nuts, but have a locating boss and welding projections. The bosses also keep weld spatter out of the threads. [2] Retainer weld nuts
