fixing ear posts to titanium?
Hi folks,
I'm looking at a pair of titanium hoop earrings, but I'm stumped as to attaching the posts to them. The only way seem to have any semblence of success is to drill the hoops, and press the posts in, and crimp (punch) the material to mechanically lock the posts in place. I tried silver solder on the titanium, and th esolder simply beaded up (similar to dirty metal) despite the amount, or quantity of flux applied. Has anyone got any tips or suggestions on this issue? thanks, Des |

Has anyone got any tips or suggestions on this issue? thanks, Des Ok I can help you here, 1... You cannot silver or anyother metal braze titanium. 2. you can join it as follows 3. resistance welding 4. argon arc welding 5. flash but welding also known as capacitor discharge plasma welding 6. fine silver sweating under high vacumn. induction heated. so without these speciallist techniques in your work shop,all your left with are mechanical methods. you havnt described what the hoops are made of. tube? sheet? wire? the solution to your problem will be determined by the rest of the design. Ive made lots of titanium products including ear drops rings etc. All my findings ive made from titanium (999 pure) wire as an ear wire hook with saftipin latch. All from one piece of wire. They last in use about 20 years. till the wear in thwe drop's hole and the wire requires themn to be replaced. your problem is to get enough titanium wire at the right price to work out a design and production method to suit your experience. |

From what I know of Ti, it cannot be soldered in any fashion, but can be
welded in three ways: --easy, but expensive--lasers. Most of the laser welders for jewelry advertise that they can work Ti. Buy, Lease or fine someone to do it --difficult, and cheapish--explosion. You can explosion weld Ti to itself or dissimilar metals, obviously only if you know what you're doing --ignore this one--hammer. You can forge weld Ti to steel, and I would assume other Ti, but I don't know how The other option would be to thread the posts and tap the hole, and screw the posts into the hoop, perhaps with a bit o' the locktite. If you go to some of the knifemakers BBSs, they can give some tips on working with Ti Aaron In article , "Des Bromilow" wrote: Hi folks, I'm looking at a pair of titanium hoop earrings, but I'm stumped as to attaching the posts to them.

Has anyone got any tips or suggestions on this issue? thanks, Des within the jewelry industry, the usual approaches a 1. Using a titanium post with an attached pad, which allows the use of cold adhesives (glue) rather than soldering. Easy and cheap if the design allows it, but sometimes less permanent. Requires a design with sufficient attachment area for a decent size pad, plus must allow the thickness of the pad plus adhesive without looking too bad. Probably not what you need here. 2. Use of laser welders with argon gas shielding. Fast and effective, if you happen to have access to a 30 thousand dollar laser welder... 3. Use of capacitance discharge spot welding, also known as fusion welding. Perhaps the fastest, and most common method. The machines range from rather pricey commercial units, to the little "Sparkie" type units that cost a couple hundred dollars from Rio Grande. With these units, welding titanium or niobium ear posts to almost any jewelry metal (including aluminum) becomes quite easy and very fast (takes just seconds per weld). Main downside is that it requires specially made posts with a little "nib" on them that produces the electric arc that actually allows the weld to occur. Not a major problem, as such findings are widely available. If you dont' have access to these methods, then mechanical "cold joints", such as threading the post, and a matching hole, and gluing in, or riveting on, the post, or some such also can work. If that doesn't work, then the easiest method is to find someone available, such as myself, who has the needed equipment, who could do it for you. In my case, it would cost you the two way postage, plus the cost of the findings, and a few bucks to weld it. Contact me via email if you are interested. Peter |
