The process of 5g gold ring is mainly welding. Two pieces of metal are closely welded and fixed together by electric welding to achieve decorative effect. The welding method can be resistance welding, arc welding or laser welding. Resistance welding is usually used. The surface of the metal sheet can be coated with a layer of meltable metal, and then the two metal sheets can be welded together by current, so that they can be firmly combined to achieve the decorative effect. Of course, other welding methods, such as arc welding, can be used if necessary. This method mainly fuses two metal plates together by discharging, which requires high technical conditions and technicians to ensure the welding quality. Laser welding is also a common welding method. It uses a laser beam to weld two metal plates together, with high welding speed and better welding quality.
