PhotonWeld: Handheld Laser welding Machines for metals
Welding metal with Light - Welding metal with Photons
Today, welding is an innovative mounting technique that is used in all areas. While the technique itself is widespread, some of its processes are not yet as well known and underused. Laser welding falls into that category and, despite its false reputation as a complex process, offers many unparalleled advantages in terms of speed, technology and costs.
Compared to traditional manufacturing processes such as resistance spot welding or conventional ARC welding, Fiber Laser Welding offers easy operation, very simple to learn with a fast learning curve, improved energy efficiency, smaller ecological footprint, lower maintenance requirements, less enviremental contamination, improved machine lifetime and faster cycle times for high-volume production.
Consequently, the processing speed is maximized; material costs and operation costs are minimized.
The precision provided by fiber lasers is particularly useful for manufacturers switching to precise, thin-walled and lightweight designs made of light or very resistant materials. Significant weight reduction is achieved by minimizing the size of parts and components via fiber laser welding, while safe engineering is fully enabled by wobble-beam fiber welding.
Fiber laser welding, like other laser-machining methods, is a non-contact technology that has a limited, heat-affected zone (HAZ), which is why the technology is a preferred method for welding delicate products at high speeds. Laser welding is also a more repeatable and consistent process than other welding methods, and is capable of producing high-strength bonds without the need for filler material, flux, prepping, or secondary cleaning and finishing processes. Fiber Laser Welding has enabled many applications, such as energy storage with lithium ion batteries and implantable medical devices, to be manufactured in extreme scales, at much lower costs, with greater consistency, at greater speeds, and with much less waste and quality-control issues. Moreover, a laser welding manufacturing process is much more reliable than other welding technologies, as the latest laser-welding machines require little to no maintenance, and virtually no downtime.
Laser welding does not operate on the same principles as other types of welding like TIG, MIG, MAG,..
Laser welding uses a beam of light, instead of electricity, to join two pieces of metal together through a melting and cooling process.
Another key difference with laser welding is the intensity and ability to focus the heat source: the laser. The much higher, focused heat than, say, the electricity of a MIG welder or TIG welder, means that the weld occurs much more quickly. What’s more, the ability to narrowly pinpoint the weld area leads to much greater precision and more accurate and attractive weld joints.
What does this mean for you?
Higher speeds: till 10x faster than MIG welding, and till 40x faster than TIG welding.
Minimal/no finishing: The accuracy of the laser welding process means that little to no grinding or finishing is needed.
Visually superior: Laser welding is ideal for straight line joints in furniture and other consumer products, since there is a much smaller heat-affected zone and a much tighter weld.
Greater strength: A smaller heat-affected zone also means less weakening of the material.
So when wouldn’t you want to use laser welding? Thicker materials and parts where the weld joint construction does not allow the fit-up to be consistently maintained generally are not good candidates for laser welding.
