Some basic common sense of silver welding wire
I don't know if you 've ever heard of a welding product. On weekdays, we all see its mysterious figure, but it is generally aimed at those who are engaged in welding maintenance, that is, silver welding wire. When I haven't touched it, I have been silly to think that silver welding wire is a kind of silver welding wire that uses silver instead of ordinary welding wire, but when I unveiled its mysterious veil, I found that its secret is more than a little! So, what is the standard of silver welding wire?
The physical properties of silver welding wire: silver electrode is a kind of electrode containing silver or silver-based solid, which has excellent process performance, low melting point, good wettability and gap filling ability, high strength, good plasticity, excellent conductivity and corrosion resistance. It can be used for brazing all ferrous and non-ferrous metals except aluminum, magnesium and other low melting point metals. The products are widely used in refrigeration, lighting, hardware and electrical appliances, instrumentation, chemical and other industries.
The characteristic advantage of silver welding wire:1.The silver electrode has good fluidity, low price and excellent process performance;2.Silver electrode has low melting point, good wettability and gap filling ability;3.The silver electrode joint has high strength, good plasticity, excellent conductivity and corrosion resistance;3.Copper-silver brazing is self-brazing and does not require flux. Suitable for contact welding, gas flame welding, high frequency brazing and some furnace brazing. The brazed joint has good strength and electrical conductivity.
The silver electrode of silver welding wire has low cost, saves silver and substitutes silver, and is suitable for welding copper and copper alloy. Application areas:Widely used in refrigeration, lighting, hardware and electrical appliances, instrumentation, chemical and other industrial manufacturing fields.
Effect of silver welding wire of different materials:HL301Ag10Cu53ZnThe composition. This silver welding wire is mainly used for some hard steels and steel alloys.
HL302Ag25Cu45ZnThe composition. The silver welding wire made of this material has a characteristic, that is, it has very good conductivity, so it can be applied to some alloys, such as steel alloy stainless steel.
HL306Ag65Cu20Znof the ingredients. In the manufacturing process of electrical equipment, this kind of silver welding wire material can be well welded, and the welding of copper alloy with stainless steel materials such as electric water heaters, refrigerators, and air conditioners can play an important role.
