In our tutorial on welding on ear studs<\/a> we present a different approach on how to repair broken earthing pins with the PUK. This workshop now looks at another approach. Our example is a broken ear stud pin of a 750\/000 white gold ear clip with a tourmaline cabochon. <\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Remove any solder at the break point. It burns explosively during welding and leaves porous areas. Also file the area slightly flat so that the connector has a good contact surface later. If necessary, drill a hole in the center of the plate so that the plug can be fitted afterwards. Preparation and cleanliness of the welding area are extremely important for a stable and durable end result. <\/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

Make the ear stud as usual. You also need an eyelet that closes exactly around the ear stud to create additional material and a stable repair.
Now either position the eyelet with a little protrusion so that it fits into the hole or, if there is no hole, leave it flat without protrusion. Then solder the eyelet to the ear stud. <\/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

<In this case, the welding geometry joint\/angle situation is ideal. The required material is already on the ear stud – in the form of the eyelet – and only needs to be melted onto the ear clip. This mode is assigned a special welding curve (HF superimposed) in order to be able to weld better in such situations. Rather shorter welding times are best suited here (5 ms or less). <\/span><\/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

Position the electrode at a 45\u00b0 angle. (For silver, make sure that the angle of the electrode is as parallel as possible to the ear stud). Weld once around the ear stud to melt the material of the eyelet evenly and thus create a clean transition from stud to ear clip. <\/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

If necessary, model the material slightly by positioning the electrode at different angles to the applied material in order to move it to the desired position (see also WS2\/2.2<\/a>). In this way, you can minimize any subsequent finish. As always, please note: gold, platinum, stainless steel etc. have the property of being moved towards the electrode, while silver is moved away from the electrode, as it flows more fluidly than gold etc. <\/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

Finally, clean up the ear stud and take care to remove as little metal as possible so as not to weaken the weld unnecessarily. Sanding is perfectly possible here, as
enough material has been applied using this method to create a stable, durable repair. <\/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
