Resistance welding is commonly used for joining steel sheets. These machines have evolved over the years. There is no metal filler needed, and the heat for the weld pool is created by means of resistance when a high welding current is directed through the welded work pieces. This technique is a highly efficient production method that is particularly well-suited for automated mass production and production lines.
Resistance welding is ideal for small batch production because this method is flexible, the equipment used is simple and the process is easy to control. Though these machines are highly priced they help provide quality welds, every time and at the required production rate. Seek the advice from the experts as they suggest the most cost effective and economical spot welders. Spot welding is one form of resistance welding. Spot welding focuses on specific points to weld and not on connecting the entire metal object. This technology allows you to perform repairs on previously welded objects.
Spot Welder is used in contacting metal surfaces welded by the heat from resistance to the electricity flow. Sheets having thickness of 0.5-3.0 mm are joined using this process. Determining the appropriate welding parameters is a very complex issue. A small change in one parameter has a major effect on other parameters as well. The contact surface of the electrode is gradually increasing making it difficult to design a welding parameter table. The table displays optimum parameters for different circumstances.
This kind of equipment takes care of almost all welding safety requirements for various industries and is also easy to install. Few industries where this equipment is used are heavy machinery and water equipment. Different metals of various thicknesses require different current amplitudes, time intervals and types of electrodes. For instance, if the equipment is not properly installed it could end up delivering too much or too little energy to the sheets being bonded. If too much of energy is delivered the sheets would melt excessively, which creates a whole in them rather than a weld. However, if the amount of energy is too little that will be insufficient to melt the metals and bond them.
