With the rapid development of science and technology and industrial economy in recent years, the demand for greenhouse aluminium profiles is increasing, and the research on the weldability of aluminum alloys is also deepened. The wide application of aluminum alloy promotes the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy. Therefore, the welding technology of aluminum alloy is becoming one of the research hotspots.
Aluminum is a face-centered cubic structure, so it has high plasticity and is easy to process. It can be made into various profiles and plates with good corrosion resistance.
