6082 aluminum plate welding needs to know the key points of knowledge

Welding 6082 aluminum plate has high technical requirements, and it is necessary to master enough knowledge to successfully weld 6082 aluminum plate. Let's take a look at what knowledge points 6082 aluminum plate needs to master when welding.

6082 aluminum sheet

1. The inner liner must be placed with wet towels. Under normal circumstances, the welding space is relatively small, and the protection work is done.

2. Heating with mild fire welding, the flame of the welding gun can not be too long, otherwise it is easy to cause 6082 aluminum plate to melt; The electrode must be evenly coated with flux to ensure the quality of the solder joint.

3. The welding time should not be too long, the melting point is too low, and the time is too long, which is easy to melt and thin the 6082 aluminum plate wall, and it is easy to leak when it is pressed.

The above is the welding of 6082 aluminum plate need to pay attention to some matters, we can take this as a reference in accordance with the correct method of welding 6082 aluminum plate to ensure good welding effect.

Which type of aluminum plate has better thermal conductivity and durability?

Now people's requirements for materials are getting higher and higher, like aluminum plate people in the choice of thermal conductivity and durability have requirements, it in the field of decoration, lighting, furniture cabinets will be applied, can also be used in building external walls, aluminum plate commonly used models there are many, aluminum plate which type of thermal conductivity is better and durable?

1, 1060 aluminum plate is a kind of high purity aluminum plate, its physical properties are stable, with excellent corrosion resistance, electrical and thermal conductivity. Under high temperature conditions, 1060 aluminum sheet shows good stability and heat resistance. The experiment shows that the high temperature resistance of 1060 aluminum plate can reach about 300℃, which ensures its insulation effect to the recommended extent.

2, 1 series aluminum plate

1 series aluminum plate called industrial pure aluminum plate has good elongation and tensile strength, good plasticity, corrosion resistance, electrical and thermal conductivity, the production process is relatively single, the production technology is relatively mature, the price has a huge advantage over other aluminum alloys. Disadvantages are low strength, can not be strengthened by heat treatment, machinability is not good, not easy to braze, easy to pressure deformation.

3, 2 series aluminum plate

2 series aluminum plate is called duralumin, the main alloying element is copper. Has high strength and good cutting performance, has a certain heat resistance, heat treatment, the disadvantage is poor corrosion resistance. Mainly used in aircraft structure, aerospace, weapons, engines, pistons, automobile body, ship hull and stress components.

4, 3 series aluminum plate

The main alloying element is manganese. The strength is higher than that of industrial pure aluminum plate, and the formability, welding property and corrosion resistance are good. Since it can not be strengthened by heat treatment, cold processing is used in the process to improve its mechanical properties. It is mainly used in the application scope of industrial pure aluminum plate and other fields with higher hardness requirements, often used in kitchenware, food and chemical storage and transportation, heat sink, home appliances and other fields.

5, 4 series aluminum plate

Most aluminum alloys with silicon as the main alloying element cannot be strengthened by heat treatment. The silicon content is usually between 4.5-6.0%. Low melting point, good melt fluidity, easy to fill, good corrosion resistance; It has good wear resistance and heat resistance, mainly used in welding materials
