How hard is it to weld Aluminium?

Yes, aluminium is a complex metal to weld. This light metal has the characteristic of softening under heat which can cause deformation.
In addition, some aluminium alloys requiring may suffer losses in mechanical properties depending on the welding process. It is therefore essential to choose the right parameters for the type of aluminium to be welded.
Welding aluminium is thus a much more complex operation than for other metals. Welding aluminium requires a great deal of expertise and adapted tools such as FSW tools. Stirweld facilitates the assembly of aluminium with the design of an FSW welding head that fits on any machining centre.
