Advantages of Laser Welding
Welding metals is the most common and generally understood use of laser welders, but plastic welding has become the norm in several industries, such as medical devices and automotive manufacturing. Things not possible just a decade ago are now being done with no additional additives, and with weld seams that are mere microns wide.
It’s easy to see why laser welding has become so commonplace. The advantages over traditional methods are numerous, and have led to enormous savings for the industries and manufacturers that have embraced it.
- Seam Quality – weld seam structure is excellent, and often secondary finishing is not required due to little to no burring.
- Non-Contact Welding – no need for tooling replacement due to wear and tear, and less stress on weld pieces.
- Cleaner Processes – laser welds can often be done without filler material, and leave virtually no debris
- Precision – a laser’s localized energy means excellent thermal control, low distortion, very close tolerances, and a very repeatable and consistent weld.
- Speed – the ability to focus energy to exactly where it’s needed, with no spikes or dropoffs, mean material can travel through the weld path at faster speeds…up to 200 inches/min.
- Cost – welding with lasers has been shown to reduce costs by as much as 90% through faster weld speeds, considerable energy reductions, and less required labor/weld.
Industries Commonly Using Laser Welding
The advances in laser welding have broadened its application to thousands of new products.
- Medical Devices Manufacturing – the MDM industry requires exact tolerances, weld seams that are near invisible, and clear on clear plastic welding.
- Aerospace – the need to weld a wide range of alloys and metals make the laser’s ability for control and precision highly desired.
- Automotive – with a car needing some 4,500 welds in the factory, not including any done on assemblies built by suppliers, and steel, alloys, and plastic materials in use, the automotive industry has widely adopted laser welding into its processes.
- Other Industries – Laser welded construction can be found in almost any consumer product industry, from solar panels to housewares to sporting goods to wristwatches. Large or small scale, the versatility, speed, and efficiency of a laser beam is hard to beat.
