Everyone who works as a welder knowsSilver solderThe price is relatively high, so the success rate of welding is very important. The professional skills of the welder improve the success rate. So what welding method is used for silver solder? Here are some tips for novice welders.

1. Welding equipment

Due to the low melting point of silver solder, small oxygen welding equipment, liquefied gas welding guns, or gasoline welding guns are generally sufficient.

Before welding, preparations such as temperature and cleanliness must be done in advance.

Welding failure can occur if the temperature is too low, leading to poor fluidity of the silver solder.

　　Silver solderThe welding area must be cleaned well to remove impurities and oxidation layers to ensure that the solder can fill and fuse properly.

3. Flux

Silver solder powder and borax; in many cases, flux may not even be necessary.

　　Silver solderDuring welding, sufficient professionalism is required; otherwise, welding failure not only wastes solder but also affects subsequent welding.

Note: Silver solder has process characteristics such as a low melting point, good wettability, and the ability to fill gaps. It also has high strength, good plasticity, conductivity, and corrosion resistance. It can be used for brazing all black and non-ferrous metals except aluminum, magnesium, and other low melting point metals. Silver solder is widely used in manufacturing fields such as refrigeration, lighting, hardware electrical appliances, instruments and meters, chemical industry, aerospace, etc.
