Aluminum profiles are also common in our life. They are generally light in weight and have good strength. Besides, they have good corrosion resistance. Because of some properties of aluminum, aluminum profiles are often not easy to rust. There are many kinds of aluminum profiles, one of which is called patterned aluminum plate, and its application is more common, and its appearance is more beautiful, so it is welcomed by everyone.
1. Hot cracking is easy to occur in the welding of patterned aluminum alloy.
2. The welding joint of patterned aluminum alloy is severely softened and its strength coefficient is low, which is an excessive obstacle to the application of patterned aluminum alloy.
3. Refractory oxide film is easy to be produced on the surface of patterned aluminum alloy, which requires high power density welding process.
4. Pores are easy to occur in aluminum alloy welding.
5. Aluminum alloy with pattern has high linear expansion coefficient, which is easy to cause welding deformation.
6. Pattern aluminum alloy has high thermal conductivity, and at the same welding speed, the heat input is two to four times higher than that of welded steel.
From the above, we can know that the welding process of welded aluminum checker plate adopts the method of high energy density, low welding heat input but high speed. There are many kinds of aluminum profiles in our life. As long as we observe a little, we can find that with the development of our industry, science and technology, the demand for patterned aluminum sheets is also increasing.
