No disadvantage of welded gold is not useful. The gold -free gold is more than 999.9 ‰ of gold, that is, the use of welded welding technology during the production process of gold jewelry, and increased the gold content of gold from 999 ‰ to 999.9 ‰.
The solving the lack of color formation of gold jewelry because of the lack of welds, the phenomenon that is easy to change color at the welding joint after long -term wear, and even causes the skin allergies of the wearer. A progress is also a one -step leap. The advantages of no weld gold: The advantage of weldless gold in anti -corrosion and abrasion resistance is very obvious. It is said that the technical requirements of non -welded gold are much higher than other golden requirements. Through a series of processing tools, advanced production equipment and optimization production processes can be used. Inspection of the national testing department. This -free gold manufacturing process in my country has reached a high level internationally, so many people like to buy non -solder gold jewelry.
