Lastek 15

Welding of Titanium

TIG rod for welding pure titanium.

Very corrosion resistant (against chlorous solutions like seawater, hypochlorite,…).

Specifications & Usage


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.
