Welding Steel using FSW IMPORTANT WELDING ZONES • Friction stir weld in its cross-section consists of three main zones: (a) Nugget, stirred zone, (b) thermo-mechanically affected zone (TMAZ) (c)heat affected zone (HAZ). • The three zones pose distinct mechanical properties and nugget and TMAZ being the weakest part of the joint. friction welding. It is a friction welding process that uses flywheel or kinetic energy for the heat source and a high- pressure system for the forge force. Because of the high pressure, the metal, as it becomes heated by friction, is forged together with no melt product being produced, i.e., no chemical change and a very narrow HAZ. Ceramics can be friction welded to metals but the type of metal used has to be carefully selected. It is much easier to weld metals which have good plastic flow characteristics, for example aluminium, copper, lead, etc. The ceramic may suffer ther.

In the developed model of inertia weld-ing of two similar specimens, Moal and Massoni  introduced a friction coeﬃcient changing together with rotational speed and pressure and others  presented a three-dimensional model of friction weld.
The role of friction welding as a production process is considered and the main advantages and disadvantages are discussed. These are then demonstrated by considering three case studies of parts which have been manufactured using the friction welding process.

Introduction to Friction Welding: In friction welding one piece is rotated and the other is made to rub against it under an axial load resulting in increased friction, heat generation and joining when the pieces are brought to rest under sustained or enhanced axial load, as depicted in Fig.
Friction welding is a solid-state process (non-fusion) that is achieved through frictional heat. This heat is generated by controlled contact of two components until material reaches its plastic state, at which time plasticised material begins to form layers that intertwine with one another.

The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it. The frictional force can be expressed as. F f = μ N (1). where. F f = frictional force (N, lb). μ = static (μ s) or kinetic (μ k) frictional coefficient.
N = normal force between the surfaces (N, lb) There are at least two types of friction forces. In comparison with mild steel, for example, the austenitic stainless steels have several characteristics that require some revision of welding procedures that are considered standard for mild steel. As illustrated in Table 2, the melting point of the austenitic grades.

Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool. It is used in the cladding of stainless steel to mild steel for corrosion resistance. It is used in making bimetallic strips. Roll welding is used to produce sandwich strips to convert it into coins.
Applications of hot pressure welding. It is used in the aerospace industry. It is used in plastic welding.
Friction welding (FRW) is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called "upset" to plastically displace and fuse the materials.
The most commonly welded materials are aluminium, mild steel, stainless steel and their alloys. is the torch is subject to a number of wear components such as contact tips, nozzles, liners etc. It is often a process that TIG welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.
Bi-metallic & Similar and dissimilar material welding: With friction welding, we can bond certain material and alloy combinations that are considered either un-weldable or poor, through conventional welding methods, for example: Copper to Aluminium (Aluminum - USA), Copper to Stainless Steel, Aluminium to Stainless Steel, Mild Steel to Stainless Steel, Titanium to aluminium, and many more.
