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.
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.
How does burning rubber create friction?
Burning rubber creates Friction because friction creates heat and burning is heat
Friction is a force that?
...creates heat.
How does a oven create heat?
a oven creates heat by burning gases slowly
Is it required to do pickling and passivation on Tube to tube sheet welding on Stainless Steel Heat exchangers?
yes
What is polarity in welding?
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
What is plasma welding?
Plasma welding is another name for arc welding. It is a process in which electricity super heats air to form a plasma arc. This arc transmits an electrical current to a metal surface and creates heat to melt the metal together thus creating a weld joint.
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 are the two polarities used with direct current welding?
reverse polarity and straight polarity The answer is right but a bit of furthur explanation is required. Polarity can be changed in DC output welding sets. The heat of the welding arc is concentrated on the positive terminal. So when thick plates are welded as more concentration of heat is required on the job the job is kept +ve ie. straight polarity is used. For thin plates concentration of heat is on the filler rod ,so reverse polarity is used.
What is the term tw refers to in welding?
TW = thermite welding, a welding process that requires no external source of heat or current.
What is the difference between welding of metals and plastics?
because of the difference in physical characteristics of thermoplastics and metals, there are corresponding differences between welding techniques for metals and thermo-plastics. in the welding of metal, welding rod and parent material become molten and fuse into the required bond to form welded joints. this is not in thermo plastics, because they are poor heat conductors , they are difficult to heat uniformly .. so diifferent methods are used to weld plastics...
What is used in welding?
A device that can generate heat. Melted material and the welding operation is performed.
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.
What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
How you calculate heat input and traveling speed for Gas Metal Arc Welding?

Are heat resistant gloves good for welding?
Yes heat resistant gloves are a good idea for welding though very thick leather welding gloves are most commonly used and safest. Global Industrial is good.
