A white gold necklace is to be reworked. There are three stones set in yellow gold in the center. The outer settings are to be removed to make earrings. The middle stone remains in the necklace. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The necklace is separated at the points indicated.
Some material from the outer settings should remain at the ends of the necklace chain. The connection points are filed flat to create a well-fitting welding joint. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The weld seam can be neatened up well at these joints later on. If you were to weld directly to the white gold chain, old solder and galvanic coatings such as rhodium plating would also have to be removed. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The material at the end of the collier chain is welded all the way around to the middle frame. The standard setting with 30 % welding power and 4 ms pulse duration is used for this. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The eyelets are welded all around with the following setting:

A freshly ground electrode should be used in order to be able to weld successfully in the narrow joint in the front area of the eyelets.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
