Question

In arc welding the operational current value is decided by

Answer 1

Thank you for asking this question .
Let me help you in finding the answer.
Arc welding is actually a type of welding in which amount of heat inputs determines the current value while in case of 'voltage' the length of the arc is relatable.
For the purpose of manual welding, the continuous supply of current is important factor. Tungstan arc welding is one of the example of arc welding.
Hope this will help you.

Answer 2

Arc welding is the process of joining one metal with another using electricity. The electricity generates the heat required to melt the metals. When the molten mass cools down, it results in the fusion of the metals. Some common types of arc welding are:

# Shielded metal arc welding

# Gas metal arc welding

# Flux-cored arc welding

# Submerged arc welding

In arc welding, the operational current value is decided by the amount of heat applied that is applied as input for the process to take place.
