Problems solved by technology

In the processing of pure gold jewelry, people usually use welding powder or welding rod to weld jewelry, and the above methods are used to weld jewelry, which is easy to form large solder joints, which is not convenient for subsequent processing and production. The efficiency is low, and it is not beautiful, especially when the jewelry is welded by the above method, the composition of the solder powder or welding rod is different from that of the pure gold jewelry, which will also reduce the fineness of the pure gold jewelry. This phenomenon, for the fineness of 99.99 More than 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001

Embodiment 1

[0011] In a working environment with a temperature of 15°C and a humidity of 60%, the clasps of the necklace are made of raw materials with a gold content of 99.999%, and the necklaces prepared by the clasps are placed neatly to ensure flexibility and moderation. After the connection is completed, Adjust the flame head of the hydrogen-oxygen welding torch so that the flame temperature of the hydrogen-oxygen welding torch is 1065°C, and the welding line energy is kept at 200 joules / cm. , to achieve rapid fusion welding, control the weld seam formation coefficient between 1 and 1.1, after polishing, car embossing, control the concentrated sulfuric acid at 300 ° C to soak the necklace for 30 seconds to remove oil and impurities, and use an agate knife or The steel calender is polished to make a ten thousand pure gold necklace.

Embodiment 2

[0013] In a working environment with a temperature of 20°C and a humidity of 45%, the clasps of the bracelets are made of ten thousand pure gold materials, and the bracelet connections prepared by each clasp are placed neatly to ensure flexibility and moderation. After the connections are completed, adjust the gasoline welding torch. Flame head, so that the flame temperature of the gasoline welding torch is 1070 ° C, the welding line energy is kept at 220 joules / cm, and the outer flame of the welding flame is moved at a speed of 1 cm / s along the direction of the welding part of each buckle chain, and each ten thousand pure gold The welding part of the bracelet is melted and even bonded to achieve rapid welding and welding. The welding seam formation coefficient is controlled between 1.1 and 1.2, and each buckle chain is welded and connected in turn, and then polished, turned, and concentrated sulfuric acid is controlled at 305°C Soak the necklace for 32 seconds to remove oil an...

Embodiment 3

[0015] In a working environment with a temperature of 25°C and a humidity of 50%, semi-finished jewelry is made from raw materials with a gold content of 99.999%. The flame temperature of the welding torch is 1065°C, and the welding line energy is kept at 210 joules / cm. Use the outer flame of the welding flame to melt and even bond the welding parts of the semi-finished ten thousand pure gold jewelry, so as to realize rapid fusion welding and control the weld seam formation coefficient Control it at 1.1, and then go through polishing treatment, embossing, soaking in concentrated sulfuric acid and polishing treatment to make Wanzu gold jewelry.

Abstract

The invention discloses a technology for welding k-gold jewellery, the technology is as follows: under the work environment with the temperature of 15-25 DEG C and the humidity being less than or equal to 60 percent, two or more pieces of k-gold jewellery semi-manufactured products are set level and the welding positions thereof are aligned. The outer flame of welding flame with the temperature of 1070+ / -5 DEG C is used for melting the welding position of each k-gold jewellery semi-manufactured product so as to realize the rapid heat sealing and welding. Furthermore, ratio of weld formation is controlled within 1-1.2. The welding technology is adopted for effectively ensuring the relative purity of gold in the jewellery. The welded jewellery has no welding spot and has smooth surface; meanwhile, energy conservation and consumption reduction can be achieved, welding power can be saved and the production efficiency can be increased.

Description

technical field [0001] The invention relates to a gold jewelry processing technology, in particular to a welding process using ten thousand pure gold as a material to process jewelry. Background technique [0002] The so-called Wanzu gold jewelry refers to jewelry whose finished gold jewelry has reached or exceeded 99.99% fineness. In the processing of pure gold jewelry, people usually use welding powder or welding rods for welding jewelry, but using the above methods for jewelry welding, it is easy to form large solder joints, which is not convenient for subsequent processing and production. The efficiency is low, and it is not beautiful, especially when the jewelry is welded by the above method, the composition of the solder powder or welding rod is different from that of the pure gold jewelry, which will also reduce the fineness of the pure gold jewelry. This phenomenon, for the fineness of 99.99 More than 10000000000000000000000000000000000000000000000000000000000000000...
