According to national regulations, the content of pure gold must reach 99.99%, so it is required that no solder can be added in the welding process of gold during processing. However, there are many kinds of gold connections now, and the solderless welding process can be truly achieved technically. So far, the brand of Gold Welding is only Safir.
Every piece of Seifer's ten thousand gold jewelry is engraved with the words "ten thousand gold AU9999", while the so-called "ten thousand gold" of other brands is actually only marked with "AU9999" on the jewelry, and there is no written seal of the words "ten thousand gold". These words are engraved by the seller himself, which can not only raise the price, but also hide the inspection by the quality inspection department.
