30 welding rod main characteristics includes: 1) high welding effect 2) low melting point 3)various types to choose This type of welding rod is a type of mediate welding material which has good welding effect ,low melting point ,fine wettability and shaping, electrical conductivity and corrosion resistance. It also makes the welding joint smooth. the welding rod is widely applied in manufacture industry like refrigeration, electrical household appliances, electric machine, electrical appliance and apparatus, ect. the welding rod can be used in all the ferrous metals and nonferrous metals.By adding tin and rhenium, it not only lower the cost of silver but also the melting point. This type of welding rod will be melting quickly and filling in the blank of base metal. It makes the welding joint strong and smooth. This type of welding rod will be melting quickly and filling in the blank of base metal. To make the welding joint much stronger, it is also available to be applied in other welding materials.
