Flux is used in soldering toa)fill up gap in the jointb)dissolve oxide...
The action of flux in soldering joints is
(i) to break and remove the oxide layer formed along the joined faces.
(ii) to aid the capillarity of the molten metal and facilitate its flow around and through the joint.
(iii) to act as cleansing agent for the removal of dirt etc.

Explanation:
Flux is a chemical substance that is used in soldering to facilitate the soldering process. It is applied to the surface of the workpiece before soldering, and it helps in the following ways:
Dissolving Oxides:
The main purpose of flux is to dissolve the oxides that form on the surface of the workpiece during the soldering process. Oxides are formed due to the reaction of the metal with the air, and they can prevent the solder from adhering to the surface. Flux dissolves these oxides and ensures that the solder adheres to the surface properly.
Lowering Melting Temperature:
Flux also helps in lowering the melting temperature of the solder. This is important because different metals have different melting points, and if the melting temperature of the solder is too high, it can damage the workpiece. Flux lowers the melting temperature of the solder and makes it easier to work with.
Filling Gaps:
Flux can also be used to fill gaps in the joint. When the solder melts, it flows into the gap and fills it up. This creates a strong bond between the two pieces of metal.
Washing Away Surplus Solder:
Flux can also be used to wash away surplus solder. When too much solder is applied to the joint, it can create a weak joint. Flux helps in removing the excess solder and ensures that the joint is strong.
In conclusion, flux is an essential part of the soldering process. It helps in dissolving oxides, lowering the melting temperature of the solder, filling gaps, and washing away excess solder.
