I wanna play with some.
Is it at all possible ever to weld it? Maybe with electricity or hydrogen/oxygen? Can it be hammered on to any useful end? I specifically want to drill tiny holes in a silver ring and insert tiny rods of titanium into those holes and have them stay. Oh, and can one cut it with a jewelers saw and file/sand/polish it? -- Si Hoc Legere Scis Nimium Eruditionis Habes |

I think he knows, given that in another post, he suggests that he is already of "enhanced size"... :-) If you want me to chew it for you, from now on the fee is $150.00 per hour, with a minimum retainer of 4 hours. Fortunately, most other readers of this newsgroup, (which was specifically set up for the purpose of people involved in the craft of jewelry to have a place to discuss the various technical and aesthetic aspects of the craft, which would surely include basic questions about titanium working) are more generous with their advice and time here. (so are you, Abrasha, even if you claim otherwise (grin)) And besides, if everyone with a question or topic to bring up went to Google or another forum first, then this one would never get any posts of any interest. Certainly not that sort for which a small cadre of possibly bored pros sits around and waits, since it gives them the opportunity to spring into action and display their knowledge for a no doubt awstruck world... Kinda like those country redneck boys who own a sturdy pickup truck for no other reason than they know, with certainty, that if they wait long enough, someone in an ordinary car will run off the road and require their services to help pull them out of the ditch.... By the way, regarding forging titanium. Some alloys are almost impossible, it's true. But commercially pure (CP) titanium isn't too bad. It work hardenes quickly, so there's only so far you can forge it. But often, if you plan ahead, that's enough. Don't plan on annealing it. That requires a high vaccuum or inert atmosphere to do. For most jewelers, most welding or joining methods used in industry aren't an available option. The PUK welders work with it, as do the jewelry laser welders if you've got an argon gas shield. I find the results a bit spotty with mine, but the argon shielding setup on my laser isn't so great. Sparkie fusion welders, used to put on various findings like ear posts and the like, work great with titanium, either putting titanium findings on other metals, or findings of other metals onto titanium. This offers some joining capabilities, since an ear post welded to your titanium, can also be thought of as a rivet attached at one end, and ready to rivet over on the other. But barring these types of welders, most jewelers working with titanium content themselves with cold joining methods like rivets, screws, glues, etc. For your inserted wires, I'd suggest using an annealed CP titanium wire/rod, with holes drilled the exact size so the wire can be forced in. Then slightly open up the outer bit of each side of the holes, giving a chamfer. Then you can lightly peen over the wires, upsetting them as rivets. After filing flush, the bit forced into the wider chamfers will hold them in place just fine. Peter |

For example, this, cold- forged from wire (CP, from Reactive Metals): http://www.jarkman.co.uk/catalog/jew...tisquiggle.htm or these, from sheet (unknown alloy, from a surplus dealer): http://www.jarkman.co.uk/catalog/jew...tipendants.htm or this (again, unknown alloy, but probably 6/4): http://www.jarkman.co.uk/catalog/jew...oiseripple.htm It does work-harden, but on this scale you can mostly overcome that by using a bigger hammer. Oh, and can one cut it with a jewelers saw and file/sand/polish it? Yes, but you'll get through blades fairly quickly. R. |

You have shown what just having a go will produce and not being afraid to hit it!!. Ive been a titanium smith for some 20 odd years and here's a couple of tips for you. When youve made your item, polish it well. then fire oxidise it to a colour well past the blue stage. Use an oxygen free flame that envelops the whole piece. Then polish off the high spots and reoxidise again to a lower temp. this way youll get a 2 colour efect, and using fire youll get a much harder oxide fiish. Show us the results you get Stick to 99% titanium if you can. Go to Google and type in Ted Frater bronzesmith and minter to see the titanium bowls ive made. Update for you all on this group. just deliverd the past 2 months work. 2500 hot forged commemorative plaques for the 40th Great dorset Steam fair. Ted Frater Dorset UK. |
