Q What do you know about Series welds in spot welding?

It is a welding method in which two or more spots are produced simultaneously with only one common but indirect current path.

In series welding, a portion of the secondary current by-passes (shunts) any weld nugget being formed. This shunt current passes through one of the panels being welded.
