Description

Technical Field

[0001] The invention relates to the technical field of gold and silver jewelry processing, in particular to raw material welding equipment for gold and silver jewelry processing and manufacturing. Background Art

[0002] With the continuous expansion of the gold and silver jewelry market and the increasing demand of consumers for jewelry quality, higher requirements have been placed on the precision, efficiency and quality assurance capabilities of raw material welding equipment for gold and silver jewelry processing and manufacturing. Jewelry manufacturers need to be able to quickly and accurately weld gold and silver jewelry of various complex designs, and ensure that the welded jewelry has a good appearance and quality. In the field of gold and silver jewelry processing and manufacturing, traditional welding methods have many problems. For example, manual welding was a common method in the early days, which was highly dependent on the experience and skills of craftsmen. Due to the low melting point of precious metals such as gold and silver, it is difficult to control the flame temperature during manual welding. If the flame temperature is too high, it is easy to cause excessive melting of gold and silver, change the original shape and size of the jewelry, and affect its precision and beauty. In the jewelry processing industry, laser welding technology is widely used because of its advantages such as high precision, high efficiency and low energy consumption. Specifically, this technology uses the high energy of the laser beam to act on the surface of gold, so that its surface quickly reaches a molten state. When the laser beam stops irradiating, the gold surface quickly cools and solidifies, thereby achieving welding.
