Welding is a fabrication process whereby

Welding is a fabrication process whereby two or more parts are fused together by means of heat pressure or both forming a join as the parts cool welding is usually used on metals and thermoplastics but can also be used on wood the completed welded joint may be referred to as a weldment various names like flux shielded arc welding manual metal arc welding, or stick welding is known as shielded metal arc welding it is a manual welding process that uses an electrode covered with flux to perform welding AC or DC power supply forms an electric arc between the electrode and the metals to be joined gases used in welding and cutting processes include:

 shielding gases such as carbon dioxide, 

argon, helium, etc fuel gases such as acetylene, propane, butane, etc the essential purpose of welding is to join two elements together with a firm connection welder typically work with metal or thermoplastic and use durable filler material to bind them together. Welding is used to creating many modern constructions, such as skyscrapers, cars, ships and aeroplanes.
