Titanium is most commonly used for rings because the hard metal is difficult to solder or mold into intricate shapes or to engrave because laser engraving is the only type of engraving method that works well on titanium.
These do-it-yourself kits are available in a wide variety of types, and each kit includes everything you will need to complete the job including solar cells, solder, soldering iron, flux, and all necessary connections.

Fusing them together by a blow-pipe without the aid of solder (which would be quickly destroyed by the acid).

Microscopic accuracy has to be attained in cutting out the space for the insertion of the design, and while the latter must be soldered firmly in its place, not the slightest trace of solder or the least sign of junction must be discernible between the metal of the inserted picture and that of the field in which it is inserted.
In "autogenous soldering" two pieces of metal are united by the melting of the opposing surfaces, without the use of a separate fusible alloy or solder as a cementing material.
