Welding powder is used for welding materials, is also a piece of metal materials, can melt and material integration, welding powder is not only one kind of welding powder, can be divided into many kinds, each kind of welding powder contains different components in the inside, also they play different roles.

Type of solder powder

Disposable flux main raw material for organic solvent, resin and its derivatives, synthetic resin rosin surfactant, organic acid as activator, rust preventer, cosolvent, film former. Simply say all kinds of dissolved solids in various kinds of liquid forming uniform transparent mixed solution, the proportion of components each are not identical, different role.

Organic solvent: one or several mixtures of ketones, alcohols and esters, commonly used including ethanol, propanol and butanol;, isobutyl ketone;Ethyl acetate, butyl acetate, etc. As a liquid component, its main role is to dissolve the solid components in the flux, so as to form a uniform solution, which is convenient for welding components to be evenly coated with an appropriate amount of flux components, and it can also clean the light dirt and grease on the metal surface

The function of welding powder

Welding powder, also known as flux, its main role is slag, easy to remove metal oxides;At the same time can also reduce the weld metal 塎 points, improve the metal fluidity, solder powder flux, the nature is to help welding, the welding of different materials with flux is different also, the gas welding copper silver with borax flux!Now the silver base and copper base welding powder are commonly used, welding powder flux generally has three functions:

1. Melt cover isolation and oxidation prevention

2. Clean welding surface with corrosion

3. Participate in welding
