In arc welding, arc is created between the electrode and work by:
Flow of current
Voltage
Material thickness
Contact resistance
Flow of current
In arc welding, arc is created between
the electrode and work by flow of current.
Hence, the correct option is (A).
&Key Points:-
Arc welding is a welding process that is used to join metal to metal by using electric current to create enough heat to melt metal, and the melted metals when cool result in joining of the metals. As electric current increases, the arc length decreases and vice-versa.
