What is the difference between friction stir welding and friction welding?

Friction stir welding also known as FSW means that the metal is not melted during the process of joining. This is a solid-state process in which you use a third "body" tool to join two surfaces. Between the tool and material a lot of heat is created which results in a soft region in the metal close to the FSW tool. Friction welding or FRW is also a solid-state welding process whereby heat is generated through friction between a moving tool and the component being worked on. A so-called lateral force "upsets" the materials being joined in such a way as they are fused. No melt occurs during the process, friction welding is therefore not really a welding process in the sense of electrode or gas welding. It is a technique for forging metals together. Friction welding is commonly used with special metals in the aviation and the automotive industries.

What type of friction acts on a spoon when you stir it?
skin friction
Give relation between friction lubricant viscosity?
To determine the viscosity of a given lubricant start out with an appropriate viscometer. Make sure the cup is cleaned well and use leavening screws to make sure that the meter is level. Put the ball valve close to the jet and pour in test oil. Place a clean flask inline with bottom of discharging jet. Insert a thermometer and stir the water constantly while heating. When desired temperature is obtained, stop heating. Lift ball valve, start stop watch, and the oil will flow into the flask. Stop stopwatch when it reaches the 50ml line with the meniscus. Record time.

What is the difference between beat and stir?
beat is to whisk at a certain speed stir is to turn liquid slowly
Why do you stir iced tea after you put sugar in it?
We stir iced tea to dissolve the sugar because the added friction helps to break the sugar molecules apart.
Why does salt dissolve quicker when you stir it?
Because the water is moving faster and there for heating up and causing more friction.
What factors speed up diffusion?
Increase the temperatures so the molecules move faster. Stir the solution so friction helps out more. Increase the concentration difference.
Why do you need to know the cooking terms?
If you don't know the difference between stir and fold, for example, you will have a flat angel food cake! Truthfully, a slight difference in degree will make a truly great meal or a mediocre one.
Does it make a difference whether you stir anti clockwise or clockwise?
it depends on the size of the spoon.
