Laser Welding Titanium

Welding titanium by using inert gas – flexible and precise with brilliant results

Because of its relatively low density, high stability and strength, titanium alloy (ASTM grades 1 to 5) managed to assert itself quickly in modern industry.
All common titanium alloys are reliably weldable through reproducible parameter selection, such as laser power, pulse peak power, frequency, and pulse shaping. A controlled inert gas atmosphere (helium or argon) prevents welds from becoming brittle. The small heat-affected zone ensures the material’s basic characteristics like strength and hardness remain unchanged.

Pulsed laser welding of titanium is particularly beneficial for thin-walled components due to weight and strength advantages. When the process is executed accurately, high-strength and gas-tight welds are guaranteed. Depending on requirements, we will weld with or without the use of filler materials from individual manufacturing to automated series production.
So, if you are looking for a service provider you can absolutely rely on at any time, KURIOS is the right place to be. We will be happy to receive your contact regarding laser welding of titanium.

Laser welding of titanium – possible areas of application

Titanium offers many advantages in terms of weight optimization, heat resistance, stability, and biocompatibility. We weld implants and precision assemblies for the field of medical technology.
Titanium alloys are often used in sensor technology when aggressive environments meet extreme temperatures. For those purposes, we are able to weld sensor cases with already integrated electronics, since the welding process is practically cold.
