CNC laser welding

Laser welding creates a deep, narrow penetration weld through the absorption of laser power by thermal conduction or ‘keyholing’. It typically uses less heat than conventional welding and directs it more closely. We have made a significant investment in laser welding equipment in order to provide a comprehensive precision machining offer and fast turnaround times, avoiding the need to send work outside the company.

For example, there is a growing demand for rotors and stators made from electrical non-orientated steel laminations, particularly in the hybrid automotive sector. By combining our laser welding skills and our ability to produce and service the tooling to manufacture individual laminations, we can provide a total solution for this market.

If the fit between the two parts to be welded is good, there is no need to add additional material by using e.g. a welding rod. We can also add material, for example in tool and mould repair in order to build up worn surfaces so that tools can be refurbished, and if a part has been made too small so that it can then be machined again to the correct size.


Our laser welding equipment can create both spot welds, using a galvo head to deflect the beam, as in laser marking, and seam welds, using overlapping spots or with a continuous beam. We test the quality of the resulting seal to pressures from 3bar to 10bar, depending on the end requirements.
