2. Stud welding - Wikipedia

   en.wikipedia.org/wiki/Stud_welding

   Short cycle stud welding [3] is a faster form of drawn arc stud welding which can use capacitor discharge weld studs instead of drawn arc studs. This method can tolerate welding studs to thinner sheet metals than the drawn arc process, though it does not achieve welds that are as strong or penetrative.

5. Clinching - Wikipedia

   en.wikipedia.org/wiki/Clinching

   One benefit of clinching is the capability to join prepainted sheet metal commonly used in the appliance industry without damaging the painted surface. Clinching is an important means of fastening aluminum panels, such as hoods and decklids, in the automotive industry, due to the difficulty of spot welding of aluminum. [1]

6. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   Spot welding is typically used when welding particular types of sheet metal, welded wire mesh or wire mesh. Thicker stock is more difficult to spot weld because the heat flows into the surrounding metal more easily. Spot welding can be easily identified on many sheet metal goods, such as metal buckets.

7. Welding - Wikipedia

   The efficiency is dependent on the welding process used, with shielded metal arc welding having a value of 0.75, gas metal arc welding and submerged arc welding, 0.9, and gas tungsten arc welding, 0.8. [75] Methods of alleviating the stresses and brittleness created in the HAZ include stress relieving and tempering. [76]
