                                 MANUFACTURING OF WELDING ELECTRODE


Welding electrode is highly consumable industrial item. Demand of quality electrodes is always high. Demand of Welding electrode is directly proportional to the production of Steel in that country.
It is one of the most profitable business.
Electrodes are made of a core wire. That wire has a coating of Flux.

These steps are involved in the manufacturing of electrodes:-

1.       PREPARATION OF CORE WIRE:-
Core Wire is made of mild steel. It is in the coiled form. It is straightened and cut into standard size(350-450 mm). Straightening & cutting is done in a single unit.

2.       PREPARATION OF DRY MIX:-
Various minerals & alloying element is mixed in desired proportion according to the requirement of job.(Discuss it later).
We have to maintain the Flux chemistry here.

3.       PREPARATION OF WET MIX:-
To make wet mix we need Some binder. Normally silicate of potassium & sodium is used. Water is mixed. Wet mix is then pressed in a hydraulic press to make briquettes.

4.       EXTRUSION :-
Briquettes is fed into the extrusion cylinder of press. While the wire is fed to it by wire magazine of the machine. After that wire get coated with flux. Coated electrode  come out on conveyor. Grinding of its end is done automatically on conveyor.

After that electrode is kept in tray. Then it is sent to the baking room. After sufficient baking it is packed.

Many people have made a lot of money by entering in this business.

Those two people has started an electrode manufacturing company that manufactures general & Special purpose electrode by scientific techniques.
