Laser Processes
With Welding,Cutting,Drilling and Marking making up the laser processes available with GSI lasers, we pride oursleves on our experience and knowledge in these application areas.
- Successful laser welding depends upon the selection and proper application of the right laser system and basic laser welding & fixturing techniques. At GSI Group, our JK™ Lasers address most all laser welding applications.
When considering laser welding, some of the critical factors are materials, weld joint design, component part preparation, part fixturing, automation, and pre- or post-welding operations.
Laser welding is usually done without filler metals so parts need to have good fit-up with a gap less than 15% of the thickness of the thinnest component. Parts should be relatively clean since the welding is very fast with no time to burn-out contaminants. Shield gas is required for more reactive metals but many alloys can be welded in air.

our JK™ Lasers, JK™ Fiber Lasers, and eCO2 Lasers all accommodate a wide range laser cutting solutions. There are many benefits of laser cutting. Some of these are applicability to a wide range of materials and thicknesses, narrow kerf widths and high speeds, and very high repeatability and reliability. Laser Cutting Machines are easily automated and programmable and reduce tooling costs and set up times.

There are several patents concerned with controlled cutting of glass with zero width and other brittle materials in a straight line using CO2 laser beam. Laser glass cutting produces a high quality cut edge with minimal microcracking. This is achieved using a controlled cleaving of glass through a combination of heating and cooling. Laser separation of glass with zero width can be summarised by... Click here to read more.
- Laser drilling has found successful manufacturing applications in the aerospace, automotive, energy, electronics, medical, pharmaceutical, and consumer goods industries. Lasers make it possible to machine very small holes, unusual-shaped holes, blind holes, and precisely tapered holes. Laser drilling is used to drill holes at steep angles, and to process difficult-to-machine materials. Click here to read more.
- Laser marking represents the largest number of
installations for the industrial application of laser technology. At GSI Group, our Spectron and eCO2 Lasers all address various laser marking applications.
Our Lasers employ a wide range frequency pulsing output with high peak power to produce very fine and controlled marking and ablation in a very small spot size.

Laser cutting works by directing the output of a high power laser, and focussing it to a small spot on the material to be cut. The material then either melts or vapourises. Removal of molten material is achieved by using a relatively high pressure assist gas. As the beam moves relative to the material a cut channel (the kerf) is formed, having an edge with a high quality surface finish.
We have White Papers on these processes, including reports specific to Heat Treatment and Heat-Treating
