In controlled amounts these elements increase toughness; in extra they damage ductility. The four grades of CP titanium (ASTM Grades 1 through 4) are effectively differentiated by their greatest allowable oxygen and iron content: ASTM Grade
When TIG welding, you should have a pre-circulation of about 5 seconds ahead of initiating an arc plus a write-up-move of twenty five seconds. Your circulation price ought to be close to 25psi with argon and all over 28 or so with an argon/helium mix.
