CD STUD / BASE METAL COMBINATION WELDING CAPABILITIES RECOMMENDATIONS

Capacitor Discharge Studwelding has applications in many areas of metal fabricating, metal joining and welded fastening. The combinations of Weld Stud and base metal materials are quite numerous including the welded combination of just about any weldable material. In some instances, Capacitor Discharge operations can be used to accomplish the welding of dissimilar metals. The Chart below reviews some of the more popular, volume combinations of Weld Stud and Base Material.

*Good: Generally full strength results, depending upon the combination of stud size and base metal.

**Other materials, such as 7000 Series aluminum, titanium alloys, Inconel, etc, can be welded under specific conditions.

CD STUD REVERSE-SIDE MARKING LIMITATIONS

The charts on the following page will be of help in determining the best combination of stud weld base size and base metal thickness. The terms on the chart are defined as follows:
• EXCELLENT — No marking, excellent weld.
• ACCEPTABLE — Visible markings, excellent weld.
• UNACCEPTABLE — Unacceptable marking, base metal failure.

It should be noted that the MIDWEST FASTENERS charts are based on optimum laboratory conditions. Even under optimum conditions, it is difficult to determine the precise point at which reverse-side marking will appear. Therefore, these charts should be used only as a guide.
