Why are elements added that cause ferrite to form in the weld?

To determine

Use of ferrite in weld.

Explanation

In FCA welding, a consumable tabular electrode containing flux, the flux itself protects the weld from atmosphere, producing bothgaseous as well as liquid slag protecting the weld.

Arc is produce between a continuously feed tabular wire electrode and work piece. Arc melts the end of the electrode and work piece.

Flux protects molten metal weld pool from the atmosphere so that atmospheric gases should not entrap in molten metal. Flux reacts with molten metal which Improves strength of weld through chemical changes in flux...
