Today's automotive industry is important to the economy in the past decade very seriously. It is associated with industrial parts manufacturing and related industries. Therefore, the demand for a wide variety of materials and are more specific. Need to develop materials and manufacturing processes conform to the needs of the user. Different types of materials, welding is one of the development process to create an alternative for designers and manufacturers. Requirements, there are different types of materials, welding and more. Dot resistance welding can weld Assembly very quickly result in high production rate is affected by the heat of deteriorated less and do not use solder materials. It costs less to a variety of materials, welding and welding a smooth work surface after high-strength against strength enough to point. Nachimani Charde [2] was made to study the growth of welds by different types of material and different thickness. Even the materials used in the experiment are 304 grade stainless steel and carbon steel, low. I found that the influence of the thickness of the material is not the crucial role that makes up the welds raengboriwen hardness and tensile strength increases. From the synopsis above is not clear, it is our motivation. In this time.
