1, thousands of gold welds are all self-fluxing, and laser welding machines and gold wires are commonly used to connect components, and the other is mass production chain making machine (the specific welding method is unknown, and it is estimated that it is also laser welding); Because it is related to the purity of the product, neither pure gold nor pure gold can be welded with K-gold tabs. Except for some small accessories. There are strict requirements in this relevant national standard.

2. 18K gold welding lug is suitable for welding gold alloy with purity below 75%, and welding lug with the same purity is generally used for welding.

3. The K-gold welding lug can be self-matched, but the corresponding purity requirements should be guaranteed. For example, 14K welded joints cannot be used for gold alloys with purity greater than 14K gold. The melting point of K-gold welding lug depends on the composition and melting point of the joint metal.
