Fabrication notes
Machining
Titanium runs at low surface speed with heavy positive feed, sharp tooling, rigid fixturing and high volume coolant. Dwelling glazes the surface and work hardens it. Chips are combustible, so manage swarf. We can supply rough machined, saw cut, waterjet or near net blanks to cut down the metal removed.
Welding
Readily weldable by GTAW, plasma, electron beam and laser processes with full inert gas shielding of the pool, root and cooling weld. Contamination shows up as colour on the bead and as embrittlement, so shielding and cleanliness govern the result.
Forming
Cold formability is limited compared with steel, so hot forming, generous bend radii and stress relief after forming are normal practice. Surfaces must be clean of iron pickup before heat treatment.
