Laser micro welding joins very small parts using laser beams. It is different to normal welding processes because it does not use a lot of heat and it can focus on small areas to put them together easily.
How It Works
Micro welding joins small components in an accurate way The laser makes a very small spot of heat that melts the metals just enough to join them together. This works well for parts that are very small, very thin or sensitive to heat damage because it helps to protect sensitive components.
Why Use Lasers Instead of Traditional Welding
Normal welding like TIG or MIG puts too much heat into small parts which can damage them. These processes also send an electrical current through the parts which can damage sensitive electronics. Laser welding solves these problems by using only light instead of electricity to make the connection and it uses very little heat on the parts. This makes welds exactly where they are needed and can also reduce the warping and shrinkage of the materials. If your metals need electroless nickel plating, firms such as poeton.co.uk/surface-treatments/plating/electroless-nickel-plating can help.
Challenges of Working with Small Parts
If you work with very small components it can be difficult because some parts are as thin as a human hair. Special tools are needed to handle these tiny pieces without damaging them. Engineers have developed methods like vacuum tweezers which can safely pick up and position these parts during the welding process.
Common Uses for Micro welding
Laser micro welding is used to make many important products. It can make medical devices like stents, surgical tools and implants that go inside the body, electronic packages that need to be sealed well to protect sensitive components and instruments where small, strong connections are needed. Micro welding can also make heat exchangers and other devices that have very thin walls.
As products keep getting smaller and more complex, laser micro welding will become more important for manufacturing high-quality, reliable devices that work well in many different situations.
