With the resurgence of the automotive industry and other sectors of the economy, such as the building construction industry, the need for stud welding continues to be on the rise. With over 20 years of stud welding experience, Midwest Fasteners understands the importance of quality stud welding products, especially for these industries as well as in other sectors of American manufacturing and construction.
Here at Midwest Fasteners, stud welding is our specialty. Stud welding can be defined as a process in which a metal weld stud fastener can be applied onto metal parts using a controlled welding arc. A stud gun is used to place the weld stud on the metal whereby a weld arc melts the stud’s base and the receiving material. The welding stud is then placed into the material and both metals re-solidify. This process allows for welding to occur without the metal being pierced or punctured, making it the perfect choice when welding materials onto containment vessels like holding tanks that contain liquids or other surfaces where a fastener is needed but surface condition and characteristics cannot be compromised. Stud welding is also extremely fast; the process is completed in seconds.
There are two popular methods of stud welding: capacitor discharge stud welding and arc stud welding. Capacitor discharge studs are used when dealing with thinner base metals and can also be used on some dissimilar metal combinations. The process leaves no reverse side marking, only needs 110 volt power as input, can weld up to twenty times per minute, and is used with stud welded fasteners that are under 3/8” diameter or less. Arc stud welding is used for heavier metals with the feature of placing fasteners up to 1-1/4” diameter and needs at least 220 volt power sourcing, or direct current. Ceramic arc shields insure that the weld fillet base is maintained properly under Arc Stud Welding applications.
