Ask the master to give a brief introduction to the history of the development of welding technology

China's welding technology is not very clear... I know a little about tenoning and riveting...

Before the end of the 19th century, the only welding process was the forged welding of metal, which had been practiced by blacksmiths for hundreds of years.

The earliest modern welding techniques appeared at the end of the 19th century, first with arc welding and oxy-gas welding, and later with resistance welding.

In the early 20th century, the demand for military equipment in World War I and World War II was great, and the corresponding cheap and reliable metal joining process was emphasized, which in turn promoted the development of welding technology.

After the war, several modern welding techniques emerged, including manual arc welding, which is currently the most popular, as well as automatic or semi-automatic welding techniques such as MIG/MAG arc welding, submerged arc welding (submerged arc welding), flux-cored wire arc welding, and electroslag welding.

In the second half of the 20th century, welding technology developed rapidly, and laser welding and electron beam welding were developed.

Today, welding robots are widely used in industrial production.

History of Welding More than 3000 BC, forging welding technology appeared in Egypt. More than 2,000 years BC, China's Yin Dynasty used casting and welding to manufacture weapons. Before 200 B.C., China had mastered the brazing of bronze and the forging and welding of iron.

1801: The arc was discovered in England.

In our country, welding operations need to be licensed, welders are the type of work that belongs to the access category, in the professional qualifications of skilled personnel, only five of the 81 types of work in the access category, welders are one of them, and the actual situation is that most of the industry practitioners are unlicensed operations. With the continuous standardization of technology and the relevant requirements of the industry, more and more people want to take a welding certificate, the advantage of the certificate is still very large, first of all, the salary of the certificate and the non-certificate are very different, often able to reach more than double or higher level. Therefore, the issue of short-term welder training has naturally become a concern for practitioners.

Welding as an industrial "tailor" is a very important means of processing in industrial production, the quality of welding plays a decisive role in the quality of the product, so, what is the future development of welding technology?

Industry outlook. With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry.

At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

Welding is an important part of the manufacturing industry, and the rapid development, so to the welding industry has brought unprecedented development opportunities, welding, argon arc welding, welding and other technical types of work in the increasingly difficult employment situation is still outstanding, so it has attracted many people to choose to enter the welding industry. Because people see the bright employment and development of the welding industry, the employment prospects of the welding profession are very good!

The development prospects of welding in the future are also very good, and they are more inclined to automation and intelligence.
