Jewelry welding skills:

1. Ion welding technology is to assemble a plasma welding system on a chain loom. The whole equipment is controlled by a microcomputer, and the broken chain, chain density and off-line after work are automatically detected by microcomputer sensors. Plasma can be used to weld metals such as gold, platinum and silver. No other solder is needed for welding, and the welding degree is effectively ensured by melting welding of the product itself. When welding, argon gas is used for protection, and the welding position is flat and smooth. According to different metal materials and the thickness of the chain, the welding current and power can be adjusted accordingly to complete the welding of various chains.

2. Laser welding technology is to assemble a laser welding system on a chain knitting machine. Like plasma welding, the whole equipment is controlled by microcomputer, and the broken chain, chain density and line stop are automatically detected by microcomputer sensors. Generally, chain making machines are equipped with Zhang Liqi to make them run smoothly. Using the laser focusing head regulator, the focal length of laser welding spot can be easily adjusted, and the chain can be quickly and accurately placed on the plane welding spot by electronic control and adjustment of welding parameters, so that the welding is uniform and perfect. Laser welding can be applied to the welding of various metals, especially alloys such as platinum, palladium and 18K K gold.

3. Solder powder brazing is a method of batch welding the chain after it is made by using an oxidation-resistant tunnel welding furnace. Because the step of simultaneous welding is cancelled in the process of chain making, the speed of chain making is improved and the adjustment difficulty of chain machine is greatly reduced. Combining the factors of chain making and welding, brazing with welding powder can improve the production efficiency of chain making.

Powder welding is a difficult process to master among several common welding methods. If you don't grasp it well, either the welding is not firm or even false welding, or the chain is "welded to death", resulting in a large number of waste products, which not only can not improve the production efficiency, but seriously restricts the output of qualified semi-finished products.
