Types of welding machine and their application in the industry
All types of welding machines need a power source. This power source provides the necessary energy for welding, cutting or creating an electric arc. All these devices work using direct current DC or alternating current AC. In different types of these devices, by keeping the voltage or current constant, another variable is used for their effective operation. The welding industry is a broad category that does not only include joining metals together. Connecting ceramics, composites, polymers and other materials are also included in this category. For each of these cases, special welding machines are used. With the advancement of technology, changes have been made in the structure and of course the type of operation of these devices.
