Principle Of Friction Stir Welding
Welding
Welding is an operation in which two or more parts or metals (similar or dis-similar) are united by means of pressure in such a way that there is continuity in the nature of the material (metal) between these parts. A filler metal, whose melting temperature is of the same order as that of the parent material, may or may not be used.

Friction stir welding
Introduction: Friction stir welding is a solid state welding. It is the process of joining of metallic components of similar or dis-similar material with the help of a cylindrical rotating tool. After the tool put into the rotation, due to friction between tool and workpiece, heat is generated which softens the material around the tool probe. The localized plastic deformation process occurring in the workpiece due to friction. The plastic deformation occurs at higher temperature, but lower than the melting point temperature of the workpiece. The tool softens both the components around the interface and mixes the softened material from both the components around the interface to provide bonding. On cooling a solid phase bond is created between the workpiece.

Principle of friction stir welding:
At first, the sheets or plates are abutted along edge to be welded and the rotating pin is sunken into the sheets/plates until the tool shoulder is in full contact with the sheets or plates surface.

The pitch of the threading is given as 2mm. The threading is done for the right side 30mm. [b] Since the work piece is not in a cylindrical object and is having holes in it, the process is to be done in a milling machine and the drilling machine is also used in manufacturing the given component.

Smelting is the other process, which uses heat and a chemical reducing agent to decompose a metal oxide into a pure metal. Through this process, which is a redox reaction, the transfer of electrons between the two chemical components takes place. The element that loses an

Analysis Of Hatchet
1008 Words | 5 PagesI think that this book is totally fantastic. At first, I was curious why the title of the book is “Hatchet”, because I have never seen books with this kind of titles before. Later on, while reading the story, I have realized that the hatchet was Brian’s only tool that helped him to survive. The whole story made me feel thrilled from the first page to the last one, and I could learn a lot of useful things from this book.

History Of The Federation Of Organized Trades And Labor Unions
443 Words | 2 PagesThe Federation of Organized Trades and Labor Unions (FOTLU) of the US and Canada (1881) changed it’s name to American Federation of Labor in 1886. They formed because they wanted unions to be free from political groups and to be more focused on the worries of the everyday workers. The unions were made up of “craft” unions, a labor organization that brings together workers of a particular craft or trade to form a union, who were unhappy with the leaders of Knights of Labor. The Knights of Labor wanted local craft unions to exit from their international organizations and work with the Knights directly, which would help bring funds to the Knights of Labor. Forty-two delegates, 13 national unions, 12 local unions and city labor council members
How Does Air Friction Affect Atwood's Machine
1074 Words | 5 PagesDuring we test our Atwood’s machine, we asked to control the time between two weight to touch the ground in 2 second. However, it is really difficult to have difference time in 2 seconds in the real life ever we calculate to get the true mass of weights. There are two causes that we think may affect our margin of error which is the friction and the human benchmark. The friction always is the main issue of any experiments.

The process of cooling rapidly cooling down the steel creates lots of tinny grain boundaries on the surface. The small grain boundaries are called martensite, as seen in figure 1 picture C. Martensite is a very hard microstructure due to having a dense amount of grain boundaries. The martensite crystals
Welding Career Essay
