The Different Types of Welding
The primary types of welding found in industry and by home hobbyists are generally known as Mig welding, Arc welding, Gas welding and Tig welding.
GTAW or Tungsten Inert Gas Welding
TIG welding resembles oxy acetylene gas welding and requires much more know-how from the operator. Useful for undertaking top quality work whenever a exceptional quality of finish is necessary without employing too much cleanup by sanding or grinding (Source).
Arc Welding or SMAW Welding
Often known as stick or arc welding. Arc welding is easily the most standard of all welding types, is straightforward to perfect in the home for a variety of welding circumstances. Stick welding can be used for manufacturing, construction and repairs, very much well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are usually more suited to the MIG welding types.
Gas or Oxy Acetylene Welding And Cutting
Not employed as extensively for basic welding of mild steel. Is made up of mixing oxygen and acetylene gas to create a flame able to melting steel materials. It is primarily utilized nowadays for servicing work and gas metal cutting. Additionally it is common for brazing softer metals, for example copper and bronze.
It may also be used for welding fragile aluminum components for example refrigeration plumbing. Probably the most accessible of thermal cutting gear is oxy-acetylene gas cutting and plasma cutting equipment. Additional techniques range from the use of a thermal cutting electrode to be used with the arc welder machine
GMAW or Gas Metal Arc Welding
Additionally called MIG welding this welding type is easily the most commonly used and possibly the most effortlessly mastered variety of welding for business and residential use. The GMAW process would work for fusing mild steel, stainless-steel in addition to aluminium.
