Hi,

Friction Stir Welding (FSW) and friction Stir Processing (FSP), at the first have been used Aluminum, Magnesium and weak materials, while, now-days those both process are used widely for materials with high strength and high melting point, etc. such as Stainless Steel, Titanium, 5XXX series and 6XXX series of Aluminum, etc.

However, as said FSW is used to joining the polymers.

Using FSW, we were able to weld and joint the Ti 4Al 2V ( Alpha phase alloys of the Titanium ).

I've already added the abstract and images of my work in my Research gate Profile. If you are interest, you can check them.

Bests,

FSW and other solid-state joining techniques works on many materials. FSW has even been used to weld meteorite (very difficult due to varied composition and inclusions).

(DOI: 10.1016/j.actaastro.2017.09.001)

The following materials are weldable by FSW process:

Aluminium, Magnesium, Copper and Copper alloys, Hafnium and Zirconium, Inconel and superalloys, Steel and Ferrous alloys.

.Even though the FSW technique was initially developed for Al-alloys it also has great potential for welding of Mg-, Cu-, Ti-, Al-alloy matrix composites,

lead, some steels, stainless steels, thermoplastics and different material combinations, particularly those with close melting temperatures and similar behaviour such as hot workability. The present scope exists in FSW of high strength AAs specially of 7xxx and high melting point materials as titatnium and steel. Besides,some dissimilar material combination ie.steel with aluminum ,titatinum etc can also be potential area of research.

The process of welding friction Stir welding is a solid-state welding process. Although it can be used to unite most materials, it finds its largest application in the welding of dissimilar materials such as steel and aluminium, or in the welding of special aluminium alloys (AA 7075, AA2024, etc...).

Try to perform welding on AA 7XXX or 8XXX series alloys. however the weldability of 7XXX series is very poor. so you can find optimize parameter by choosing suitable filler rods.

Friction stir welding is a variation of the friction welding process and was developed aiming at the permanent union by welding of plates manufactured in structural aluminium for use in the aeronautical and aerospace sector. Among these materials are the aluminium alloys of the series 2000, 7000 and 8000, not possible to be obtained by conventional fusion welding processes. With the improvement of the process many other materials have been united with perfection, however, for the welding of any material, it is always important to consider other aspects such as quantity, process, equipment, productivity, costs.
