Spot welding, also known as resistance spot welding (RSW), is a kind of electrical resistance welding that weld overlapping metals using two electrodes. The workpieces are compressed between the electrodes in order to apply pressure, and heat is produced as a result of the flow of electric current through the resistive metals during the welding process. This enables the materials to combine, which results in the formation of a welded junction. Because the current is delivered precisely over a tiny region on the surface of the metal, the connection that is generated by resistance spot welding looks like a button or a nugget; hence, the word spot welding was coined to describe the process.
The area surrounding the weld nugget is unaffected by the extreme heat as the metals are fused utilizing huge quantities of energy in only a brief amount of time (about 10-100 milliseconds). As a result, the area that is impacted by heat is kept to a minimum, and a clean weld is produced.
Spot welding is a strong method that has completely transformed the manufacturing process by making it possible to produce goods in a much more timely and effective manner. It entails fusing two pieces of metal together at a specified spot by using an electric current to do so, which results in a connection that is both strong and long-lasting. This method is used in a wide range of businesses, some of which include the construction industry, the aerospace industry, and the automobile industry. On the other hand resistance spot welding, also known as RSW, is a form of resistance welding that is distinguished from other types of resistance welding by its use of distinct regions of joining, which are referred to as spot welds. In contrast to arc welding, the process of putting metals together with resistance welding involves combining the components by the application of electrical resistance rather than an electric arc. Here the quality of the weld may be improved by increasing the amount of time that electrodes are subjected to pressure and current flow. The warpage, melt-through, and electrode life are all negatively impacted when the welding duration is longer than what is necessary. As a result, the most effective course of action is to reduce the amount of time as much as feasible. When the thickness is great, you should not extend the duration of the exposure time but rather pulse the current and the pressure instead.
The joining technique is based on the idea of sending a current through two or more sheets that are being held together by an electrode pair while the sheets are being clamped.
