The 6061 aluminum tube is the mechanical industry USES more aluminum alloy material, its in the use of time may need to be welded, that as 6061 aluminum tube manufacturer would like to introduce to you, 6061 aluminum tube welding characteristics.
1. There is an oxide film on the surface of 6061 aluminum tube, which is not easy to be welded, and it is easy to produce defects such as slag inclusion, lack of fusion, and lack of penetration.Remove the surface oxide film before welding.
2. The thermal conductivity of 6061 aluminum tubes is relatively high.In the welding process, a large amount of heat can be rapidly conducted to the interior of the matrix metal, so when welding 6061 aluminum tube, energy consumption is relatively high. In order to obtain high quality welded joints, energy concentration and high power should be adopted as far as possible, and sometimes, technological measures such as preheating can also be adopted.
3. The linear expansion coefficient of 6061 aluminum tube is relatively large, and the welding parts are prone to deformation due to greater stress. Therefore, measures should be taken to prevent welding deformation.In order to reduce the occurrence of thermal cracks, the composition of welding wire and welding technology can be adjusted in production.
4. 6061 aluminum tube has strong reflection ability to light and heat, so it is difficult to judge during welding operation.Aluminum is weak at high temperatures and easy to weld through.
