Problems solved by technology

[0006] Second, due to the high heat, the adhesion of the solder powder is gradually reduced, and it cannot be attached to the soldering surface for a long time and detached
[0008] In addition, due to the phenomenon of reduced adhesion caused by high heat, there will be problems such as weak welding surface

Embodiment 1

[0030] Welding processing of wire with a diameter of 2m / m

[0031] First mix 320g of copper powder, 250g of iron powder, 210g of silver powder, 210g of square pillar powder, 130g of boric acid, 60g of borax, 40g of butter, and 30g of castor oil. on a metal chain. In order to prevent the chains from sticking to each other, the chains are first treated with talcum powder and then welded at 1100-1200 °C.

[0032] Welding by the above method, the welding surface will be round and not uneven.

Embodiment 2

[0034] Welding processing of wire with a diameter of 3m / m

[0035] First mix 319g of copper powder, 200g of iron powder, 209g of silver powder, 209g of square pillar powder, 129g of boric acid, 58g of borax, 43g of butter, and 33g of castor oil. on a metal chain. In order to prevent the chains from sticking to each other, the chains are first treated with talcum powder and then welded at 1100-1200 °C.

[0036] Welding by the above method, the welding surface will be round and not uneven.

[0037] The difference between the above-mentioned embodiment 2 and embodiment 1 is that the diameter of the former metal chain is 1m / m longer than that of the latter, the time required for welding increases accordingly, and the time required for welding powder to stick on the metal surface also increases. For this reason, increase the filling amount of butter and castor oil by 7-10%, and reduce the filling amount of other materials. When the thickness of the metal wire increases or decrea...

Abstract

The invention discloses a welding powder composition for an ornament metal wire and a processing method of the welding powder composition. The welding powder composition is prepared from powdered copper, zinc, scapolite, boric acid, borax, butter and castor oil in a mixing manner. The mixed welding powder composition is uniformly coated on a metal chain and subjected to welding treatment at 1100-1200 DEG C. According to the invention, a section of the metal wire with higher strength than that of a copper wire of a general ornament material can be welded, so that the metal can become a material for preparing a bracelet or a necklace. The welding powder composition for the ornament metal wire, disclosed by the invention, can be used for welding the cross section of each metal chain and connecting the metal chains with each other. By utilizing the welding powder for the ornament metal wire disclosed by the invention, the welding is firm and stout; and although the metal chain is subjected to processing such as positive scribing, negative scribing and the like and the cutting pressure or stamping pressure and the like are applied on a welded surface, the welded surface does not crack or chap.

Description

technical field [0001] The invention relates to a powder composition, in particular to a welding powder composition for jewelry wires capable of effectively welding metal jewelry chain sections and a processing and application method thereof. Background technique [0002] Commonly used materials for jewelry are non-metallic wires with low strength such as copper and aluminum. The biggest reason for making jewelry with low-strength non-metallic materials is because it is easy to weld and prevents the welded surface from cracking or cracking during processing. However, the unit price of aluminum as a jewelry material is relatively high, and its specific gravity is light, which reduces the value of jewelry. As a jewelry material, the unit price of copper is higher than that of aluminum. Copper has a high specific gravity, durability, and high jewelry value. However, as a jewelry material, its unit price is high, and the price of jewelry is also high. The unit price of metal ...
