Historical monuments, construction of building, bridges, ship building, automobile, aerospace, power plants, refineries and lots of manufacturing activities needs the process of welding and it is a part of it. Manufacturing activities need proper technology to meet the demands and the welding system is the backbone of all manufacturing activities. It is a fabrication process that joins metals, materials and thermo plastics. When you consider the history of welding, forge was the only processes introduced first and later on oxy fuel and resistance were developed. 20th century started good for the process, it saw many new processes and laser parts manufacturer welding technologies.
Mig and tig welding submerged arc and flux core were developed during 20th century and new equipment with latest technology were introduced later. The manufacturing industry came to know about the importance of services and requirement for supplies increased a lot. To cope up with the heavy requirement, welding industries started to use new tools, products, accessories and welding equipment supplies that are designed according to the latest technology. Welding techniques is classified into two methods based on the consumables such as consumable and non consumable electrode methods.
Shielded metal, gas metal arc welding, flux-cored arc welding and submerged arc are the techniques that come under the consumable electrode methods. Gas tungsten, plasma arc, atomic hydrogen, electro slag welding and stud arc comes under the category of non consumable electrode methods. Tig uses tungsten electrode and consumable techniques use electrode rod or stick for its process. Many industries use inverter machines and there are different machines for different welding techniques. Apart from the products such as mig, tig, stick and submerged arc products, the other products such as wire feeders, spot welders, multi process units and water coolers comes under the products.
Plasma cutter the new invention comes under the category of cutting products and apart from plasma cutting, plasma gouging is also done in the same machine. Different types of welder machines are available such as mig welder, tig welder, on board welder, reconditioned welder, aluminum welder, steel welder and metal welder are used for the process of welding. Fumes are dangerous, so the weldor should be protected with welding gears such as helmets, masks, gloves and with proper accessories. Welding guns and torches are important to weldor and the weldor should have proper control over it.
Consumables available for welding are tig consumables, mig consumables, plasma cutter consumables, tungsten consumables and accessories is an optional tool that are attached to welding machines and it is used for the better performance of welding. In 1881-1882 a Russian inventor Bernardos created the electric arc first and process was a tough and nobody was willing to learn welding, but today schools were started to learn and we can learn welding easily through virtual reality.
