Features of laser beam welding

High Energy Density

The laser beam provides a high energy density, allowing for rapid heating and melting of the workpiece. This results in fast welding speeds and reduced heat input to the surrounding material. Narrow

Heat-Affected Zone (HAZ)

Laser beam welding produces a narrow heat-affected zone, which refers to the area surrounding the weld joint that experiences thermal effects. The narrow HAZ helps minimize distortion and preserves the properties of the base material.

Precise Control

Laser beam welding offers precise control over the welding parameters, such as power, beam size, and focus. This control allows for accurate positioning and control of the weld, ensuring high-quality and consistent results.


Laser beam welding can be used to join a wide range of materials, including metals and thermoplastics. It is suitable for both similar and dissimilar material combinations.

Automation and Integration

Laser beam welding can be easily integrated into automated production systems. It enables high-speed and repetitive welding operations, making it well-suited for industrial manufacturing.

Parts of fiber laser beam welding machine

  1. The laser beam welding machine is equipped with a fiber laser as the energy source. Fiber lasers generate the laser beam using a fiber optic cable that is doped with rare-earth elements such as ytterbium (Yb) or erbium (Er). These lasers provide high power output, good beam quality, and high efficiency.
  2. Optics System: Similar to other laser welding machines, a fiber laser beam welding machine incorporates an optics system. This system includes lenses, mirrors, and beam delivery components to focus and shape the laser beam. It ensures precise control over the welding process and allows the beam to be delivered to the workpiece accurately.
  3. Workstation: The workstation provides a platform where the materials to be welded are positioned. It typically includes fixturing or clamping mechanisms to hold the workpieces securely during welding. Motion control systems may be incorporated to move the workpieces or the laser beam during welding.
  4. Control System: The machine features a control system that allows operators to set and adjust welding parameters. It enables control over factors such as laser power, welding speed, pulse duration, and beam focus. The control system may have automation capabilities and may include monitoring and data logging features.

How to select a laser beam welding machine

Virmer takes care of its customers. We are interested in helping you with a choice of laser welding equipment that is suitable for your production needs. Therefore, we have compiled the most important criteria to focus on when purchasing laser beam welding machines.

Laser emitter

This criterion is based on two main parameters of an emitter: its power and its brand.

The power should be chosen according to the thickness and type of the metal to be processed. For example, to weld elements up to 3 mm thick, a power of 1000 W is quite enough. For thicker material, equipment with higher power is required.

The following brands of laser emitters are in the highest demand:

  • IPG. The leader among the manufactures. Emitters of this brand are distinguished by high precision, double protection of the beam, and high quality of work performed.
  • JPT. A cheaper analog of IPG. It also manufactures high quality laser emitters. However, it is a little less effective. We recommend using it for welding aluminium.
  • Raycus. Another proven brand. Emitters of this manufacturer are designed for welding different types of metals except for non-ferrous metals.
  • Max. These laser sources will be the perfect budget solution for production focused on aluminium and stainless steel welding.

All mentioned laser emitters perform perfectly providing high quality of welding. Thus, our company recommends considering them when you are choosing welding equipment.

Applications Of Laser Welding In Metal Fabrication

Fiber Laser Welding Machines


The automotive sector relies on the laser welding process for its cost-effectiveness, quality, and efficiency. It operates in a tool-free mode and usually doesn’t need head replacements. Various automotive components such as engine parts, solenoids, fuel injectors, and air conditioning units are good examples of machining parts using laser welding.


The laser Beam welding method offers the precision the aerospace industry requires in different applications, such as airframes and security metal detectors. Laser welding techniques join lightweight and complex structures made from aluminum, titanium, and other alloys. Welding in the aerospace sector helps to reduce aircraft weight by reducing the use of rivets.

Electronics Industry

Manufacturers in electronics depend on sheet metal cutting and laser Beam welding techniques to create various advanced electronic equipment. Product designers adopt laser welding methods and utilize continuous wave, Dd: YAG, fiber, and pulse laser welders. The welding machines produce precision welds for tiny, advanced electrical components such as sensors, microelectronic components, circuit boards, specific transistors, and control units.

Jewelry and Watchmaking

The Jewelry industry employs laser Beam welding to produce and repair products with complex and fragile designs. It joins precious metals like gold and platinum, minimizing discoloration and distortion. This industry uses a “free moving” welding concept, making the operation relatively easy and safe. The laser beam maintains a fixed position while the operator safely turns the jewelry, ring, or bracelets before the beam.

The Future of Laser Beam Welding

The rapid advancement of laser technology, particularly high-power fiber lasers, has been a driving force behind the rise of laser beam welding. As this innovative welding approach continues to mature, several exciting developments are on the horizon:

Increased Automation and Intelligence

Next-generation laser welding systems will likely incorporate more advanced automation and smart features. This could include robotic guidance systems, real-time weld monitoring, and automated parameter adjustment to ensure consistent, high-quality results with minimal human intervention.

Expanded Material Capabilities

While laser welding has traditionally focused on metals like steel, aluminum, and titanium, future systems may expand their material capabilities. This could include welding dissimilar metals, plastics, or even composites – broadening the range of applications for this transformative technology.

Portable and Handheld Solutions

As laser technology becomes more compact and affordable, we can expect to see the development of portable and even handheld laser welding systems. These portable units could bring the benefits of laser welding directly to the workpiece, improving accessibility in confined spaces and enabling on-site repairs.

Augmented Reality Integration

Integrating augmented reality (AR) capabilities into laser welding systems could provide powerful new tools for operators. AR overlays could highlight optimal weld locations, track progress, and even provide step-by-step instructions to guide the welding process.


The laser beam welding machine is reliable and compatible with vast materials and applications. More importantly, it offers more desirable results than alternate welding methods. However, to determine the right laser welding technique for your products, it is advisable to consider the workpiece material and the preferred results.
