Explain the principle behind arc welding.?
Arc welding uses an electrical current to create enough heat to melt metal. Any type of welding that uses an electric arc is technically arc welding. However, most people use the term 'arc welding' to mean shielded metal arc welding (SMAW), or 'stick welding'. SMAW, MIG, and flux core wire welding use the filler metal as both electrode and filler; TIG welding uses an electric arc to heat the base metal and a separate filler rod to add metal to the weld.
When did Humphry Davy invent light bulb?
Yes he did he invnted it in the year 1809 which is a year after he invented the electric arc.
What was argon used for?
Electric light bulbs, fluorescent tubes, and radio vacuum tubes and as an inert gas shield in arc welding.
What is a plasma arc?
A very high temperature form of welding and cutting metals, using a jet of plasma.Arc plasma is the temporary state of a gas. The gas gets ionized after passage of electric current through it and it becomes a conductor of electricity. In ionized state atoms break into electrons (−) and cations (+) and the system contains a mixture of ions, electrons and highly excited atoms.A typical value of temperature obtained in a plasma jet torch may be of the order of 28000 °C(50000 °F ) against about 5500 °C (10000 °F) in ordinary electric welding arc.
How much is temperature on electric arc?
11,0000 deg. F, or 6,000 deg. C. This is roughly the same temperature as the sun's photosphere, or outer visible layer.
Is arc welding an example of electric current?
No, an example of an electric current would be using a battery to light a lightbulb.
How do you calculate diameter of electrode for an electric arc furnace?
i don't know please give me the answer
What is arc resistant?
The electric current will not travel from one end of the circuit to another.
What is an arc-hyperbolic function?
An arc-hyperbolic function is an inverse hyperbolic function.
What is a semicircle arc?
it is the diameter
What is an arc lamp?
An arc lamp is a general term for a class of lamps that uses an electric arc or voltage arc to create light. You've seen the bright light given off by electric arc welding, and the idea of the electric arc is the principle behind an arc lamp.
How do you find the area of a circle without the radius?
if you have the diameter or the arc, then you can divide the diameter by two, or you can use the arc to calculate it.
How do I find the diameter of a circle only having an arc length?
If you have only the arc length then you cannot find the diameter.
