Modern manufacturing demands precision and speed and laser welding delivers both. We’ve seen this advanced technology transform UK manufacturing with its superior accuracy and outstanding results. From automotive parts to medical devices laser welding has become essential for businesses looking to stay competitive.
We understand that choosing the right welding method can be challenging. That’s why more British manufacturers are turning to laser welding for its impressive benefits. Would you like to discover how this cutting-edge technique could boost your production efficiency while reducing costs? Let’s explore the key advantages that make laser welding a game-changer for UK industries.
Laser welding creates precise joins using concentrated light energy. This advanced technology transforms heat energy into focused beams for controlled material fusion.
Laser welding directs concentrated photon beams at specific material points to create a localised heat zone. The focused energy penetrates the material surface, forming a keyhole that allows deep penetration welding. As the laser moves along the join line, the molten material solidifies behind it, creating a strong metallurgical bond.
Key components of the process include:
The main categories of laser welding systems include:
| Laser Type | Power Range (kW) | Material Thickness (mm) |
|---|---|---|
| Fibre | 1-20 | 0.5-15 |
| CO2 | 1-15 | 0.5-20 |
