In manufacturing industry there are hundreds of metal parts that are joined together by welding process daily. Even a single typical automotive body has about 4000-5000 weld spots in it which joins about 200 sheet metal parts together. During the joining process many factors affect the final geometrical quality. One of the many geometrical factors affecting the final geometrical outcome of the metal part assemblies is the welding process considering welding sequence used when the parts are welded together. It is of course desirable to choose welding parameters as well as welding sequence that minimizes distortion i.e. both variation and deviation in critical dimensions of the final assembly. Reducing dimensional variation is of critical importance to improve the final product quality. In this paper takes an overview of various techniques used to achieve minimum distortion while the metal parts are being assembled. Form the various techniques discussed, the technique which yields the minimum distortion is the technique for optimization of welding process and leads towards the quality manufacturing.
