We have expanded our business into Laser welding. With this process we are able to repair very small or delicate components that with conventional tig welding would not be possible.

The laser is a source of heat, but has the most unique ability to focus the heat on a tiny spot. The tiny spot can be as small as 0.2mm in diameter. This allows new metal to be fused into the prent, but at a new level of precision, but with the penetration and integrity of a conventional fused deposit.

The laser is focused on the area to be welded and sililar material is then added by hand. The laser is pulsed and at every pulse a small area of filler material is welded onto the work-piece. Several pulses per second allow small areas to be built up, without any residual heat effecting nearby tolerances.

Good conducting materials like aliminum and copper alloys are welded easily, where normally a conventional weld would allow the heat to dissipate quickly. Most small edges or areas to be repaired can be laser wleded using bare hands, for control and maximum accuracy.

This process generates very little or no heat at all to the component which reduces any distortion that previously would happen with tig welding.

With this laser welding process we can weld all types of mould tool steels - P20/H13/2767/D2, Aluminum, Titanium, Nickel base alloys, Cobalt base alloys, Copper base alloys which include aluminum bronze and beryllium copper.

With this wide range of materials we can work on all Injection mould tools, Blow moulds, Press tools, Castings, Aircraft and pharmaceutical work.

Advantages of Laser Welding

1. The parts will never get hot enough to produce cracks, sinkage or discolour of the part
2. Accuracy is second to none, welding can be controlled down to a width of 0.2mm.
3. Only the area that needs welding will be worked, the laser can be controlled in such a way that we can weld within 0.025mm to an area that needs to remain weld free.
4. By putting the exact amount on, in exactly the area you want it, leaves the engineer with a quick cleaning up operation afterwards.
5. Damaged, mistakes or modifications can be tackled to give a quick and cheaper cost to getting the item fixed and back in production without having to scrap/remake the existing part.
