What is the difference between arc welding and resistance welding?
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
How sun generates energy?
By heat released from continuous nuclear fission and fusion process.
What makes a current lower and generates more heat?
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
Why does tungsten heat and light up but copper wire does not?
Copper has much less resistance, so the electricity flows thru it with little heat, where as the tungsten resists the flow and generates heat, that you see as light.
What produces heat during shielded metal arc welding?
Electrons flowing across an air gap produce an arc. The resistance built up that is needed to push these electrons across the gap produces the heat. This same resistance causes the electrodes to get hot.
What is the difference between fusion welding an resistance welding?
Fusion welding is just any welding process which inhibites the phase trasition from solid to liquid and then back to solid state, while electric resistance welding is based on purely ohmic heating of the different parts, this heat will create fusion of the metal. So; Electric resistance welding can be said to be a type of fusion welding, but not the other way around.
What is the definition of heat fusion?
heat fusion is to join things together by heat. ie plastic welding.
What is the difference between arc welding and resistance welding?
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
What type of welding is when metal is fused together by the heat of a welding flame?
It's called Fusion Welding. You answered your own question.
The basic method of fusion welding that uses the squeeze and heat process is?
thermal
How much heat is generated in a nuclear fusion?
Heat generated in a nuclear fusion depends on the resistance of the plasma and the current.
How sun generates energy?
By heat released from continuous nuclear fission and fusion process.
What makes a current lower and generates more heat?
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
What do stars do?
A star generates light and heat by nuclear fusion and radiates it away via elctromagnetic radiation.
Is the energy produced by the sun atomic fusion or fission?
It is fusion - the fusion of hydrogen into helium - accompanied by a gigantic release of binding energy that feeds the reaction and generates radiation in the form of light, heat, etc.
How do you define a star in astronomy?
A star is any hydrostatically stable plasma that generates heat and electromagnetic radiation by nuclear fusion.
