Want to know more about tantalum welding?

Tantalum is a reactive metal which wants to include elements such as oxygen, nitrogen and hydrogen at a temperature above 250 degrees.
A good weld on tantalum is silver in color. The more discoloration, the more contained elements and the more brittle the tantalum will be. Wrong welded, and so contaminated tantalum can’t be repaired.
The only way to get a good weld on tantalum is by using a purge chamber purged with 99,9999% argon.
We have five different sizes purge chambers so we can weld any product, due to the different sizes we only consume the necessary amount of argon and we can minimize the cost.
Besides welding in the protective atmosphere, it’s very important to not get too high temperatures during welding tantalum, components are absolute clean and the machining is done with HSS tools that only came into contact with tantalum.

These requirements ensure that in the Netherlands and even in the world there only a very few welding companies who weld tantalum properly and therefore we are a worldwide known welding company in this area.
Lasklus Netherlands welds a lot of tantalum components for applications in the chemical, nuclear and aerospace industry.

For tantalum welding on site, we have the skills and experience to ensure the best quality welds using customizable and modular purge chamber facilities.
