The preparation process of the inlaid ornament comprises the following steps: precious metals (including but not limited to gold, silver in this example) are made into spherical beads of equal size and approximately 1 mm;
then, carving a positioning groove on the formed three-dimensional hollowed-out piece;
and finally, dividing (grouping) welding areas according to the outer contour of the formed three-dimensional hollowed-out piece, and correspondingly welding the inlaid ornaments on each positioning groove according to the ordering of the dividing areas. Wherein different welding areas are correspondingly welded with different welding temperatures, and the temperature difference between the welding temperatures of adjacent welding areas is at least 10 ℃.
During welding, sequentially welding the inlaid ornaments in each region in a temperature decreasing manner according to the sequence of the regions;
the partition standard of the welding area is divided mainly by the distance between the welding position and the bottom tire;
The sequence of the welding areas is that the maximum distance between the welding position and the bottom tire is a first area, and then the welding areas are divided into a second area, a second area and the like in a mode that the distance between the welding position and the bottom tire is reduced.
During welding, the welding temperature of the first area is highest, then the welding temperature in each welding area is controlled to be reduced according to the sequence of the welding areas, the welding procedures of each welding area are sequentially completed according to the sequence of the welding areas, and finally the manufactured embedded ornaments (such as embedded precious stones, tiny round beads or steamed bread-shaped noble metal particles) are welded in the corresponding positioning grooves;
Wherein, the welding temperature of each welding area is controlled to be lower than the temperature of the melting point critical point of the noble metal to be welded in the welding area or 5-10 ℃;

In order to realize that the caliber of the positioning groove is 1/3 of the outer diameter of the inlaid ornament, the positioning groove is convenient to position, welding dislocation and wire pinching pattern deformation during welding are avoided, the caliber is too small, the inlaid ornament is not firmly welded and is easy to fall off, and adhesion cannot be generated during welding.
When the positioning groove is carved, the chisel used cannot be a thin-opening chisel, and the thickness of the cutting edge of the blunt-opening chisel used cannot be larger than 1/3 of the diameter of the welded noble metal ball particles, so that the positioning groove is carved accurately.
According to the invention, dense tiny noble metal particles are welded on the full-three-dimensional hollowed-out piece to be subjected to physical groove chiseling positioning treatment, so that tiny pattern fried beads are arranged to be positioned effectively, and the positions, the adhesion and the falling off are not easy to walk. The manufacturing method is simple, convenient, efficient, green and environment-friendly, and greatly reduces the difficulty and the period market of the re-engraving manufacturing of the noble metal cultural relics.
While the application has been described in terms of preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the application, and it is intended that the application is not limited to the specific embodiments disclosed.
