Piercing is process in which punch operation cuts a hole / material by tearing operation from a final piece of sheet metal. Piercing is a blanking operation
In piercing operation, the clearance is provided on Die.

The operation of cutting of flat sheet to the desired shape is called blanking. In blanking operation, the clearance is provided on punch.
The current in electric resistance welding can be regulated by Changing the primary turns of the transformer.
The electrodes are one of the most important factors in the resistance welding process but often the most abused. It is important to consider the electrode material, shape, size, tip profile and cooling.
The electrodes used in spot welding have a tip of Copper.
Seam welding is a Continuous spot welding process.
seam welding is a variant of the basic resistance spot welding process.
In seam welding a series of overlapping nuggets is produced, usually by replacing the conventional spot welding electrodes by wheels that turn as the parts to be welded are fed between them.
