Welding 6061 aluminum tube is a relatively difficult problem, mainly because of its surface of a layer of natural oxide film, then how do we carry out welding 6061 aluminum tube?Next 6061 aluminum tube manufacturer will talk about, 6061 aluminum tube welding method.

First to remove the surface oxidation film of 6061 aluminum tube, and then USES the liquid/solid compound process (i.e. liquid casting magnesium alloy package solid aluminum alloy lining technology) to develop magnesium alloy/aluminum alloy (AZ91D 6061 / al) composite bimetallic materials, surface treatment technology of 6061 aluminum tube with adding tin on magnesium alloy modification treatment technology for magnesium/aluminum liquid - solid composite interface.

Method of welding 6061 aluminum tubes:

1.6061 Aluminum tube surface pretreatment.Tin immersion process, zincate treatment process and electric galvanizing process can be used respectively to remove the surface of the 6061 aluminum tube for oxide layer and at the same time make the surface of the 6061 aluminum tube coated with a layer of metal coating to prevent the secondary utilization oxidation of the 6061 aluminum tube.

Deformed magnesium alloy.The proper amount of Sn added can refine the grain size of magnesium alloy and improve the properties of magnesium alloy.Tin can be introduced in two different ways to study the effects of tin addition on the structure and properties of the interfacial transition layer of composite materials.The experimental results show that Mg2Sn dispersion can effectively improve the microstructure and properties of the interfacial transition layer when tin is added to refine the structured transition.

3. Sn obstructs the diffusion of Mg, making it unable to form crystal nucleus smoothly and inhibiting the growth of grains.The microstructure and properties of the transition layer have the effect of positive dispersion at grain boundary on the relative improvement of the bulk structure Mg2Sn in the dendrite voids.
