Material Group 51.3 ISO/TR 15608: Pure titanium with 0,25 < O2 ≤ 0,35 %
Features of Titanium pure Group 51.3 ISO/TR 15608
Grade 3:
Moderate strength unalloyed Ti with excellent weldability, cold formability, and fabricability. Slightly stronger version of Gr. 2 Ti with similar corrosion resistance with good weldability and reasonable cold formability/ductility.
This grade material is mainly used in chemical industries and power plant cooling system components where the parts are subjected to very harsh environments.
Welding of Titanium pure Group 51.3 ISO/TR 15608
Commercially pure titanium and most titanium alloys are readily welded by a number of welding processes being used today. The most common method of joining titanium is the gas Tungstenarc (GTAW) process and secondarily is the gas metal-arc (GMAW) process. The techniques for welding titanium resemble those employed with nickel alloys and stainless steels. To achieve sound welds with titanium, primary emphasis is placed on surface cleanliness and the correct use of inert gas shielding.
An essential requirement for successfully arc welding titanium is proper gas shielding. Care must be taken to ensure that inert atmosphere protection is maintained until the weld metal temperature cools below 426°C (800°F).
