Can welding arcs be viewed remotely?

   

Frequently asked questions

For good pictures, it is important to use good quality optical (rather than TV) lenses.

Neutral density filters are used to reduce the arc light intensity so that the operator can view the welding process. It is usually necessary to remove the filter and to provide auxillary light to view the joint / weld bead when there is no arc.

Recently, graded neutral density filters have been developed with strong filtering where the arc is and less dense in the surroundings. When these filters are used, the direction of focusing is important.

It is possible to build such a monitoring system based on home video equipment.
