TIG rod for welding pure titanium.
Very corrosion resistant (against chlorous solutions like seawater, hypochlorite,…).
Aviation and space industry.
Chemical and petrochemical industry.
Welding of Titanium T35 and T40, CP Titanium grade 1 and 2, DIN 3.7025 and 3.7035, ASTM B348 grade 1 and 2.
Lastek 15 is also used for joining alfa-beta titanium alloys where a high ductility is necessary.
Welding titanium has to be done under complete argon protection (99.99% pure with dew point lower than -50 °C (-58 °F)), in the torch and at the backside of the weld.
The gas protection has to be maintained during cooling down until the welding zone has passed the temperature of 300 °C (570 °F).
The work pieces have to be degreased very carefully (acetone or alcohol) before welding.
