Welding is a fabrication process that joins materials, generally metals or thermoplastic, by causing coalescence. On the other hand, cutting is a process that is used to cut steel or other metals of different thicknesses using a different cutting equipments. Welding is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with pressure sometimes used and heat together, to produce the weld.
Welding can be done by different methods such as gas tungsten arc welding, shielded metal arc welding, submerged arc welding and gas metal arc welding. Shielded metal arc welding is also called stick welding. It uses an electrode that has flux that protects the puddle, around it.
The electrode holder holds the electrode as it slowly melts away and slag protects the weld puddle from atmospheric content. Gas tungsten arc welding is also called as tungsten inert gas and it uses a non-consumable tungsten electrode to produce the weld. Inert shielding gas such as agon or helium protects weld area from atmospheric contamination.
Gas metal arc welding is also called as metal inert gas and uses a wire feeding gun that feeds wire at an adjustable speed and sprays an argon-based shielding gas and carbon dioxide over the weld puddle to protect it from atmospheric contamination. Submerged arc welding uses an automatically fed consumable electrode and a blanket of granular fusible flux. Welding and cutting equipments are mostly used by energy, automotive and construction industries. Due to the rapid industrialization demand for welding and cutting equipment has increased globally.
