CD Stud Welding Reverse Side Marking Limitations

How to find the Optimum Combination of Stud Size and Base Metal Thickness in Order to Prevent Reverse-Side Marking

One of the benefits of CD stud welding is that you can weld to thin materials with no pronounced distortion, burn-through or reverse side discoloration.  In order to determine the best combination of stud weld base size and base metal thickness, you can use these charts as a guide.  These 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.

Excellent=No marking, excellent weld.

Acceptable=Visible markings, excellent weld.

Unacceptable=Unacceptable marking, base metal failure.
