Talk:Stud welding

Stud welding is a fastening technique of metal to metal using only one side of the base material. It eliminates drilling, punching, threading, gluing, riveting, screwing, or finishing. Studwelding is a tremendous time and cost savings.

There are two (2) main types of studwelding: Capacitor Discharge (CD) stud welding and Drawn Arc stud welding (ARC).

During the CD process, the capacitors are charged to a setting pre determined on the front of the power supply. The CD gun is loaded with a weld stud and pushed into the base material under spring pressure. The tip touches the workpiece which closes the electrical circuit. Upon trigger from the CD gun the capacitors are emptied, the stud and workpiece surface from a molten material and solidfy together forming a solid weld. The welding time for CD studs is approx 3 milliseconds.

During the ARC process, the stud touches the workpiece which closes the electrical circuit. Upon trigger, the ARC gun lifts the stud off the workpiece with the help of a solenoid (magnetic coil). The main arc is initiated between the workpiece and the tip of the ARC stud. The base material and stud melt forming a molten material and they are forced back together under spring pressure creating a weld. The weldpool solidifies and cools down. The welding time for ARC studs vary from 5 to 990 milliseconds. —Preceding unsigned comment added by Jayg8576 (talk • contribs) 20:36, 21 February 2006

Invention[edit]

So apparently we are confused as a collective mind XD
Find a citation (like we should have anyways ^_~ ), then add the correct answer back in to the article :)
(surely this shouldn't be too hard to figure out, with just a call or email to Nelson Stud Welding :> )

Competing claims:

Invented in 1939 by Ted Nelson, the founder of Nelson Stud Welding.
Invented in the 1940s by Andrew Foott-Stephens, the founder of Nelson Stud Welding.

You may want to check some explanations in a letter by Charles C. Pease of CP Metallurgical, posted on the Internet at http://studweldprod.com/downloads/nelson%20letter%20(2).pdf Dbauer-ets (talk) 18:02, 16 October 2014 (UTC)[reply]
