Question

15. Increasing

length
the arc length
the arc voltage and
of the weld pool, while decreasing the arc
the arc voltage and fluidity of the weld

Answer 1

The arc length increases with the radius of the circular path.

The arc length is directly proportional to the radius of the circular path, and it increases with the radius. This means that as the radius of the circular path increases, the arc length also increases. For example, if you have a small circular path with a small radius, the arc length will be shorter. But if you have a larger circular path with a larger radius, the arc length will be longer.

Example:

• If you have a welding torch with a long stick-out, meaning the distance between the electrode and the base metal is large, the radius of the circular path of the arc will be larger, and therefore the arc length will be longer.

In summary, the arc length increases with the radius of the circular path.
