Laser welding is a technique that enables you to join multiple pieces of components with laser heat.
Challenging the boundaries of precision
Laser welding is a process used to join multiple metal components together. In this welding process, materials are heated above their melting temperature by laser, causing them to flow. When the materials cool down and solidify, they are attached to each other.
The laser welding process is used for its precision, strength and cleanliness. For traditional welding methods, it is hard to control heat distribution. Heat quickly flows towards places that should stay cool, causing parts and components to deform. A laser allows for precise and dosed application of heat. That results in highly controlled melting and solidification. It can be used to weld the smallest metal parts together. All to produce precise, miniature components at a small scale.
Millux challenges the boundaries of precision. We use that laser welding precision to produce miniature metal parts or parts that require high accuracy while maintaining the solid material strength over the weld. From cooling channels for technical parts to parts of filters and linear motors. Most commonly we seal channels used for transportation of gases or liquids.
Millux prefers to work with its clients from the early design phase. The products we make are complex and challenging to manufacture. Only close collaboration and consultation with clients can bring optimised solutions. It maximises our chances of providing precisely what they need.
Two modes are available; conduction-limited welding and keyhole (or penetration) welding, defined by a focused laser spot power density below or above 1 MW/cm2, typically used to achieve either low (depth-to-width) aspect ratios for the weld, or deep, narrow welds with aspect ratios above 1.5. Facilitated by cost-effective tooling, Millux runs a highly industrialised, high-productivity laser welding process.
