Projection Welding Diagram. Projection welding is an ideal method of fastening attachments eg. It is named so because different projections are formed on the workpiece for effective welding.
Where the weld cycle is repetitive control set on REPEAT. Schematic Resistance Spot Welding Process Source Scientific Diagram. A projection welding is a resistance welding where high electrical resistance at the joint is developed by embossing one or more projections on one of the surfaces to be welded.
Projections need not be round.
In this welding process the design or shape of the part is used to make discreet individual contact to concentrate the current during the welding process. 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. Construction and working of projection welding. Powered by a vision to blend power saving with aesthetics Artech has today germinated into a force to reckon with in the field of resistance welding.
