Aluminum plate has the characteristics of light weight, high strength, good corrosion resistance, non-magnetic, good formability and low temperature performance, which is widely used in various welding structure products. However, aluminum plate manufacturers often encounter some difficulties in welding aluminum plates, so how can we solve them? Next, the technical personnel of aluminum plate manufacturers will explain the difficulties of aluminum plate welding and the methods to overcome them in detail.
Difficulty 1: serious softening and low strength coefficient of aluminum alloy welded joint are the biggest obstacles to the application of aluminum alloy.
The second difficulty: porosity is easy to be produced in aluminum alloy welding.
Difficulty 3: aluminum alloy welding is easy to produce hot cracks.
Difficulty 4: large linear expansion coefficient of aluminum alloy, easy to produce welding deformation.
Difficulty 5: the surface of aluminum alloy is easy to produce refractory oxide film, which requires high power density welding process.
Difficulty 6: aluminum alloy has the same thermal conductivity, the same welding speed, and the heat input is 2 to 4 times higher than that of the welding steel.
Third, by analyzing the technical personnel of aluminum plate manufacturers, we believe that the difficulties and causes of aluminum plate welding have a more detailed understanding of the specific solutions for the following reasons: the aluminum plate welding process requires the use of high energy density, small welding heat input, and efficient welding speed.
Only by mastering these methods and skills can aluminum plate manufacturers solve the problem of efficient welding. Now we have solved 6 problems. If you have any demand for this series of aluminum plates, please contact us. We sincerely look forward to your presence.
