Introduction: Resistance spot welding is a welding process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current.

Resistance spot welding offers much cleaner and faster weld than other conventional welding process. This process is most preferable for welding sheets in 0. The specimen surface has to be as smooth as possible. Then simulations need to be run for the similar test conducted in the experimental section.

Conclusion: Resistance spot welding is one of the widely used welding processes. It is mostly used to build automobile, aircraft and lots of other machine bodies.

Hence, further study on this topic will be of a great advantage in the field of industrial manufacturing. Copper and its alloys can also be joined by resistance spot welding, although spot welding copper cannot be easily achieved with conventional copper alloy spot welding electrodes, as heat generation in the electrodes and work piece are very similar.

Electrode materials typically used for spot welding copper include molybdenum and tungsten. Spot welding has applications in a number of industries, including automotive , aerospace , rail , white goods, metal furniture, electronics , medical building and construction.

Given the ease with which spot welding can be automated when combined with robots and manipulation systems, it is the most common joining process in high volume manufacturing lines and has in particular been the main joining process in the construction of steel cars for over years.

The electrodes are one of the most important factors in the resistance welding process but often the most abused Aluminium and its alloys have high thermal and electrical conductivity compared with steel and, as the process depends on In an effort to guarantee weld quality, weld parameter settings are often set close to a splash condition Surface splash and electrode sticking are a result of excessive heating between the electrode and the sheet material being joined Support for SMEs.
