Welding is very important in the modern world and plays a vital role in many areas of industry and everyday life. It is a technology that allows metal parts to be joined safely, permanently and cost-effectively. Many modern products and structures would not be possible without welding.
In the automotive industry, for example, welding processes are used to manufacture and join body and frame components. These components must have high strength and stability to withstand the high stresses they are subjected to in daily use. Modern welding processes such as MIG/MAG welding or laser beam welding make it possible to produce high-strength joints that meet the requirements of the automotive industry.
Welding is also essential in the aerospace industry. Aircraft and rocket structures must be able to withstand extreme loads without adding weight. Welding processes such as tungsten inert gas welding or plasma welding make it possible to produce lightweight yet strong joints.
In the construction industry, welding processes are used to produce and join steel girders and other load-bearing components. Again, the joints need to be strong enough to withstand the high loads they are subjected to in daily use.
In mechanical engineering, welding is indispensable for the manufacture and joining of machine and plant components. Modern welding processes make it possible to produce high-precision joints that meet the exacting requirements of the engineering industry.
In addition to these industrial applications, welding is also important in other fields. In the arts, welding is used to create sculptures and other works of art from metal. Welding is also used in the trades to join metal parts and make repairs.
In medical technology, welding is used to make implants and medical devices. Here, the cleanliness and sterility of the welding processes are particularly important.
Overall, welding is an indispensable technology in the modern world. Many modern products and structures would not be possible without welding. The development of ever more efficient and precise welding processes is helping to further improve the efficiency and quality of products and structures.
In the meantime, there are various welding processes, all of which have special areas of application as well as advantages and disadvantages. DIN EN ISO 4063 provides a list of welding processes, the most important of which are listed below:
- 111 Manual arc welding (manual electric arc welding)
- 121 Submerged arc welding with solid wire electrode (submerged arc welding)
- [131 Metal inert gas welding with solid wire electrode (MIG welding)
- 135 Metal active gas welding with solid wire electrode (MAG welding)](/welding/gmaw-mig-mag)
- 136 Metal-inert-gas welding with flux-cored wire electrode (flux-cored welding)
- 141 Tungsten inert gas welding with solid wire or solid wire addition (TIG welding)
