Spot Welding Methods - Different spot welding methods are
(i) Direct
(ii) Indirect (or series)
(iii) Push pull
(i) Direct welds. It is a welding method in which one or more electrodes oppose each other, contacting both sides of the work and with the current passing from the electrodes on one side directly through the work into the electrodes on the other side and back to the welding transformer.
(ii) Series welds. It is a welding method in which two or more spots are produced simultaneously with only one common but indirect current path.
