AWS A5.16 ERTi-1
AWS A5.16-13 ERTi-1
ERTI-1 (CP-1) Commercially Pure Titanium is the lowest strength unalloyed (or Commercially Pure–CP) grade due to its higher level of purity.
ERTi-1 Applications
ERTi-1 (Grade 1) is used in the applications where ductility is paramount, such as explosive cladding, loose linings, expanded metal, and deep drawing applications. It is also used in electrolytic applications like coated anode substrates for production of chlorine and sodium chlorate. ERTi-1 also has many uses in the aerospace, medical, petrochemical, desalination plants, and cryogenic industries.
ERTi-1 Weldability
Titanium is a reactive metal and as such it is sensitive to embrittlement by oxygen, nitrogen and hydrogen, within the weld zone area, at temperatures above 500°F. Consequently the weld metal must be protected against atmospheric contamination that may be caused by these elements. This can be most easily attained by holding the shielding gas over the weld area until it cools to approximately 600°F. Argon is the recommended shielding gas, however an argon-helium mixture will give greater penetration although at the expense of arc stability.
