In industrial context, welding refers to a fabrication process that joins materials such as metals and thermoplastics, by causing coalescence. 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 come to be a strong joint. Various processes and vigor sources are used for welding, such as gas flame, galvanic arc, laser, galvanic beam, friction, and ultra sound.
Welding machines can be broadly classified into distinct categories depending on the type of welding processes and tool used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage, often in the middle of 17 to 45 volts and 190 to 590 amperes. These types of welding machines are the least expensive and allow welders to make your mind up the yield current by whether challenging the core of the transformer in and out of the magnetic field or by allowing the welder to make your mind up from a set of taps on the transformer.
Gas Welding Equipment Power Tools
Some welding machines use an internal combustion machine or an galvanic motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines as power is first converted into mechanical and back to electrical vigor to perform the step-down affect.

Inverter based welding machines use high-power semiconductors such as the Igbt for construction a switching power furnish capable of handling high loads of arc welding. These machines turn utility electricity into high voltage and store it in a capacitor bank. The stored vigor is then transferred to a secondary transformer for producing the desired welding current.
Welding machines have simplified distinct types of machining jobs undertaken in small and large manufacturing companies. Self-operating welding machines are also in use and have helped in addition the effectiveness of welding processes.
