In industrial environment, welding refers to a production procedure that joins materials such as metals and thermoplastics. This is typically done by softening the work pieces and adding a filler material, which is often a welding rod, to form a pool of molten material that cools to become a strong joint. Various processes, energy sources and welding machines are used for welding.
Welding equipments and machineries can be generally classified into special categories depending on the type of welding processes and equipment used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage. These types of welding machines are the least expensive and allow welders to select the output current.
Other Machines use an internal combustion engine or an electric motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines.
