Welding is used for making permanent joints.

Projection Welding Machine- An overview of the projection welding machine of Artech Welders Private Limited PowerPoint PPT presentation free to view. One of the main differences between conventional sheet-to-sheet resistance welding and projection welding is that projection welding is a dynamic process involving considerable movement of the upper electrode. Projection welding is a type of resistance welding that focuses current and force to a single point or line at the beginning of a weld.

Projection Welding In Projection welding size and shape of individualwelds are determined by the presence of projectionsembossments or intersections on the metals to bejoined. Spot and Projection Welding. The resulting welds are.

Apply to Automobile manufacture home appliances electronic instrumentation aerospace and other projection welding process industry. Requires accurate control of projection height. In Projection Welding size and shape of individual welds are determined by the presence of projections embossments or intersections on the metals to be joined.

WELDING Welding is a materials joining process which produces coalescence of materials by heating them to suitable temperatures with or without the application of pressure or by the application of pressure alone and with or without the use of filler material. Advantages of Projection Welding CONT Welds may be placed more closely together Parts are more easily welded in an assembly fixture Finish or surface appearance is often improved Parts may be projection welded that could not be otherwise resistance welded Limitations of Projection Welding. Metals are heated and coalescence is achieved not through the use of an arc but through the metals resistance to electrical currents passing through them as they are held together with pressure by electrodes.

Projection welding is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Projection Welding RPW is a resistance welding process which produces coalescence of metals with the heat obtained from resistance to electrical current through the work parts held together under pressure by electrodes. Resistance Projection Welding RPW is developed by introducing high electrical resistance at a joint by embossing one or more projections on the surface to be welded Weld nuggets are similar to spot welding Fig.

The Welding is a process of joining two or more similar or dissimilar metals by heating them to a suitable temperature with or without the application of pressure filler materials and flux. 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. Projection Welding Lesson Objectives When you finish this lesson you will understand.

Resistance Projection Welding A resistance welding process in which coalescence occurs at one or more small contact points on parts Contact points determined by design of parts to be joined May consist of projections. Spot and Projection Welding- Artech Welders Private Limited took roots in 1994 with the dream of manufacturing Capacitor Discharge CD projection welding machines. Requires an additional operation to form projections.
