›› Dedacciai K-19 titanium tubing constitute a large family of high performance products.
titanium 2
They are manufactured in Ti-3Al-2.5V titanium grade, commonly named GR.9, Ti-6Al-4V, commonly named Gr.5, and Gr.2 titanium grade, in accordance with ASTM B338 rules. Grade 9 is preferred for the most structural stressed tubing of the frame, meanwhile grade 2 grade is used where ductility and workability are the more important aspect. All the tubing are seamless, cold drawn and stress relieved (CWSR). To obtain the best results from the use of this class of products, please look carefully at the drawings, and read the advices at the end of this catalogue.

Assembling of the tubing Geometrical features All the Dedacciai tubes and tube sets are designed for assembling frames based on current UCI geometry. In the choice of tubing for manufacturing a frames, please keep into account the following safety rules : •
erify that for the selected geometry you will save a V butt length longer than the thermal affected zone, and in any case longer that the tube diameter.
•
If the butt length of down and top tubing butts are not symmetrical, pay attention in the tube orientation : at the head tube joint the tube must be only mitred, and not cutted.
•
epending on geometry, it is always better to keep D top and down tubing spaced on head tube. Over imposed tubing geometries are less safe.
•
oad recommended tubing can’t be used for offR road frames.
•
ixing point and welding cordons closure points F can give origin to fatigue cracks, realize them in the less stressed areas of the joints.
•
It is recommended to completely weld the seat tube on bottom bracket, and then all other tubing.
•
Top tube and seat stays must be approximately aligned at the seat tube joint. If you want to weld the seat stays below the top tube center line, please use the “low geometry (LG)” seat tubing (not available in the titanium set)
•
o not grind and/or polish the welding cordons. D The risk of reducing the tube wall thickness is too high!

Welding and post-welding advices Before welding the tubing, carefully clean them and remove dirty and grease inside and outside of the tube in the area to be jointed. The surfaces must be smooth and without notches. After mechanical cleaning, use acetone or MEK. Do not use chlorinated solvents. The suggested welding wire is Gr.5, (AWS classification ERti-5) Also the welding wire surface state is very important: stock it in clean areas, clean it before use and handle tubing and welding wire with gloves. During the welding process any area that will exceed 400 °C must be shield from atmosphere contamination. Localized inert gas shielding or vacuum chamber is needed.
