Projection Welding Is Employed In. Applications of Projection Welding. Projection welding is a resistance welding process of joining two sheets or a sheet and a thick component or a small component like nut to a big body like automotive chasis by making raised portions or projections on one of the components where weld nugget is required to be made.
A number of welds can be made simultaneously. Short length T joints eg. 14 or 15 can be made by forming projections in.
Its the easiest and probably the most common weld there is.
