Welding is a technology that connects metal or non-metal parts together into a disassembled unit by flattening the joint to a weld (plastic or flowing) state, then solidifying or Through joint pressure, it forms a strong bond called a weld.
When welding in a flowing state, the metal joint is flushed, then completely crystallized to form a weld.
When welding in plastic state; The bonded metal is heated to plasticized temperature, then pressed to increase the diffusion, penetration, and so forth of the contact surface elements that make the elements tightly bond to each other.
Welding has become increasingly widespread in the industry, especially with the invention of new materials and welding methods. That great birth.
The following basic characteristics are:

1.1. Saving metals

Compared with welding welded joints, which save 10% to 25% of the metal mass due to the use of more detailed welding sections, the more detailed profile reduces the amount of metal lost. Due to punching holes, metal sections, etc.
Compared with casting, welding save from 30 50 50% can be thinning, no need to system out and bean, no need for cooking and cooking …
For example, the construction of a stretcher made of scaffolding, beams in construction will reduce 15 ÷ 20% of the metal compared to other types of joints; At the same time, the simpler fabrication and assembly of the rigid structure of the structure increased.

1.2- Reduce work time and labor force

High efficiency welding compared to other methods reduces the number of dangers. Compared to grafting, it reduces the number of dangers such as perforation, hole punching, hole drilling, perforation, blanking and nailing, greatly reducing the assembly time and preparation time. Welding is more likely to perform the mechanization and automation of the production process, which facilitates the improvement of labor productivity and the reduction of labor productivity.

1.3- Variety of welding materials

Ties can be connected to different metal strings: for example, welding black metal with black metal, nonferrous metals and black metals with ferrous metals. In addition, welding can link non-metallic materials together.

1.4- High weld strength, good weld

The metal welds are better than the welded metal, which is subject to static load (also in case of dynamic load bearing). Welded high strength solder joints are a major means of making high pressure materials, boilers, pipes, and so on.

1.5- Reduce the cost of equipment

Welding equipment is relatively simple. For example, an AC tig and arc welding machine consists of a crankcase transformer with a capacity of 110 crushers or 220 crushers of less than 80 crushers.
When it comes to producing new products, it is more expensive to invest in chili than the production of navel or navel. Increase product volume per unit of production.
When it comes to producing new products, it is more expensive to invest in chili than the production of navel or navel. Increase product volume per unit of production.
However, the disadvantage of the welding method is that due to localized localization of the residual stress, the metal structure near the weld is changed in the direction of worsening to reduce the load bearing capacity, welding. Easy to deform, curl the texture.
With the growing strength of general technology and the welding industry, the disadvantages of welding have been overcome; Advanced welding methods were born; The quality of welding of different metals is increasingly guaranteed. This makes it an indispensable production sector in the production of bottled water and other manufacturing industries.
