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 are welding sparks called?
The 'welding sparks' that come off during welding are metal particles from the filler metal, electrode, or base metal that are lost during welding. The standard term is spatter.
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.
What causes warpage or distortion during welding?
Warping in welding is caused by shrinkage of weld metal, faulty clamping of parts, faulty preparation and overheating of joints. Distortion in welding is caused by uneven heating, improper sequence and the shrinkage of the deposited metal.
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.
Definition of argon welding?
A.K.A. Gas Metal Arc Welding -- Semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun.
What is SMAW?
Shielded Metal Arc Welding, known colloquially as "stick".
When welding the flux on an electrode?
shielded metal are welding is also called
What has the author Mike Gellerman written?
Mike Gellerman has written: 'Practical shielded metal arc welding' -- subject(s): Shielded metal arc welding 'Welding fundamentals' -- subject(s): Welding
What is the meaning of SMAW Welding?
Shielded Metal Arc Welding, commonly called Stick welding. A shielded electrode passes a current between itself and the workpiece. Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.
What produces the heat during a shielded metal ark weld?
an electric current
What is the meaning of SMAW?
shielded metal arc welding use to electrode metal
What is for MMA welder?
s.m.a.w. shielded metal arc welding
What is full form of arc welding?
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
What is shielding gas arc welding?
shielded metal arc welding does not required any shielding gas
What is the full form of arc welding?
If you are asking for the correct nomenclature it is Shielded Metal Arc Welding.
The most commonly used welding processes are?
There are a few commonly used welding process. The top used are shielded metal and arc welding.
