Fiber laser welding of metals

Welding metal with light

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.

What is wobble laser welding?

Trepanning fiber laser head

Standard laser welding heads are designed to focus a collimated laser beam to ONE required spot size, keeping the beam path static. This standard configuration limits each setup to ONE specific application.
Our Wobble heads, on the other hand, incorporate scanning mirror technology inside our weld head. By moving the beam with internal mirrors or rotating lenses, the focal spot is no longer static and can be dynamically adjusted by changing the shape, amplitude and frequency.

WOBBLE - Fiber laser welding

Handheld fiber laser welding machine

FAST, ECONOMICAL and SAFE hand welding with a fiber laser light beam

A Handheld fiber laser welding machine is a new type of high-power, high-end continuous welding tool which adopts a high-quality fiber laser source to produce a fiber optic light beam. After transmission processing, the light is focused on the workpiece to achieve continuous welding. It avoids the two thresholds of thermal strain and post-treatment, and is environmentally friendly and pollution-free, greatly improving the joint strength and quality of welding.
Replacing the traditional arc welding with a hand-held fiber laser welding machine will not only facilitates the welding of molds, advertising characters, kitchen utensils, doors and windows, etc. but also makes laser welding possible in outdoor operations, which indicates that this traditional welding of electric welding, argon arc welding, etc. will soon be replaced by our wobble laser welding.

WOBBLE-3 ® Series

The killer of electric welding and argon arc welding

Handheld fiber laser welding offers a fast, economical and contact-free alternative for welding a wide variety of metals in virtually every industry. Whether you require, high processing speed, complex weld geometries or multi-layer joints, our Wobble-3 provides unique solutions for a diverse range of welding applications.

The wobble method produces a superior weld by greatly reducing imperfections, increasing consistency, reducing material cost and providing more tolerance for process variables.

The welds produced using the laser stir welding (LSW) process, in general, exhibited a wider fusion zone than the welds produced without beam manipulation.

Our Wobble fiber laser welder gives you back the POLE position!

Benefits of fiber laser welding

Above all, the use of laser welding for metal parts improves productivity by reducing the time spent on welding and straightening the welded parts and allows greater freedom in the designing of parts (simpler assemblies). Laser welding also helps make savings by reducing production costs and the materials consumed by the welding process. This welding method also affects the quality of the assembly by offering mechanical strength that is at least equal to that of the base material, and by reducing the part deformation rate. Laser welding is also an excellent solution for joining subassemblies of dissimilar parts or treated parts (carbonitrided, case hardened, etc.).

Benefits

  • Welding productivity can increase by up to 800 %
  • Reproducible process
  • Reduction or even elimination of the time for straightening welded pieces
  • Overall reduction of production costs
  • Mechanical resistance at least equivalent to that of the base metal
  • Reduction of welding consumables
  • Great freedom in the designing of parts
  • Fume and smoke drastically reduced
  • Few splatters and flames
  • Drastic reduction of post-processing (cleaning, grinding,...)
  • Welding of dissimilar materials (steel to cast iron, stainless steel to Inconel, etc.)
  • Welding of precious materials
  • Welding close to delicate components
  • Welding time is reduced to a tenth
  • Reduced deformation of parts
  • Welding of parts with limited accessibility
  • Process that can be automated
  • Assembly with no filler metal
