Types of Welding

Types of Welding Points : Types of Welding Process, Gas Tungsten-Arc Welding, GMAW or Gas Metal Arc Welding, Arc Welding or SMAW, Gas or Oxy Acetylene Welding and Cutting, Flux-Cored Welding, Electroslag Welding, Plasma Arc Welding, Submerged Arc Welding, Shielded-Metal Arc Welding The various type of welding process are given below:
1. Gas Tungsten-Arc Welding
2. GMAW or Gas Metal Arc Welding
3. Arc Welding or SMAW
4. Gas or Oxy Acetylene Welding and Cutting
5. Flux-Cored Welding
6. Electroslag Welding
7. Plasma Arc Welding
8. Submerged Arc Welding
9. Shielded-Metal Arc Welding
1. Gas Tungsten-Arc Welding Gas Tungsten-Arc Welding is consider to be one of mainly tricky and time consuming of welding process use today (along with Plasma Arc Welding). This is as it requires a great quantity of focus and skill due to the little area of space among the ’arc’ of flame and material being welded. Generally, small strips of metal that do not have much iron are welded by this process. Though it is not easy, it produces very strong high quality welds when done properly. Welders manufacturing bicycles and aircraft, equally commercial and military, use Gas Tungsten-Arc Welding frequently as many other welders will never come across this process. Extremely small change has been made to this process as its release in 1941.
2. GMAW or Gas Metal Arc Welding Extra generally call MIG welding this welding type is mainly extensively use and perhaps the most simply mastered type of welding for industry and workshops use. The GMAW process is proper for fusing mild steel, stainless-steel as well as aluminium. This process save lots of time and is best for a large quantity of welding work. It was first developed for use by aluminum metals. Today, this method is generally use by those welders in automobile repair and manufacturing industries.
3. Arc Welding or SMAW This welding also known as stick or arc welding. Arc welding is most basic of all welding types, is simple to master in a workshops welding place. Stick welding can be use for manufacturing, construction and repairs, very well suited for heavy metal size 4 millimetres upwards. Thinner sheet metals and alloys are generally more suited to mig welding types.
4. Gas or Oxy Acetylene Welding and Cutting This welding is not use as commonly for general welding of mild steel. It consists of mixing oxygen and acetylene gas to large a flame able of melting steels. Generally use these days for maintenance work and metal cutting. It also familiar for brazing softer metals for example copper and bronze, can also be use for welding subtle aluminium parts for example refrigeration pipes. The most available of thermal cutting gear is by oxy-acetylene gas cutting and plasma cutting machines. Other methods contain use of a thermal cutting electrode for use by arc welder machine.
5. Flux-Cored Welding Flux-cored welding was produced and locates into use in early years of 1950s. Its principle was to give another option to popular use of stick welding. Flux-Cored method is generally use for projects that require rapid speed as it is an automatic form of welding. Various construction workers use this process on job as of speed and capability to use flux-cored welding in various situations on various materials.
6. Electroslag Welding Electroslag welding came into perform in 1950s. Electroslag is a commonly rapid welding process use to connect large materials for example thick steel plates. These plates or materials are generally arranged in a vertical position, as Electroslag weld is planned to weld at this angle with no cause distortion to welder.
7. Plasma Arc Welding Plasma Welding is extremely much similar to that of Gas Tungsten Arc Welding. The two processes are frequently compared as they mostly work in similar fashion, just using a different type of torch. This process was developed in 1954, while still today, it is still being better upon. Plasma Welding too require extra concentration than GTAW as of smaller arc and precision of weld. In Plasma Welding, electrical current is approved through a very small nozzle which passes through protective gases, enable excessive precision as welding small areas. Plasma Welding can heat metals to very extreme temperatures which can result in deeper welds. Similar to GTAW, this welding method is usually used in the aircraft manufacturing industry.
8. Submerged Arc Welding Submerged Arc Welding process can simply be use suitably on materials contain high iron contents, for example stainless steel. Device use in this process can automatic or semi-automatic makes it a rather fast welding process. As it is a fast process, electrical arc must continually be covered by ‘flux’ in order to protect metal as of atmosphere during welding process. This cover too prevents some welding spatter which makes it safer for welders than a few of other forms of welding. The process is named after this require to be ‘submerged’ in a flux cover.
9. Shielded-Metal Arc Welding Shielded-Metal Arc Welding (SMAW) is too referred to like ‘stick welding’. This process is identified to be the mainly popular and commonly use processes in welding nowadays. First form of SMAW was produced in 1938 except process and equipment continues to undergo upgrades. It is a manual welding process that is extremely simple and inexpensive to work. The results frequently are not as ‘neat’ as other methods and molten splatter is a familiar occurrence. Stick welding is generally use with construction welders working on steel structures and other industries that need welding but do not have large finances.
