Gain an Advantage with Robotic/Cobotic Laser Welding

Robotic/cobotic laser welding is a cost-effective and flexible application for achieving high quality weldments. The combined flexibility of the robotic arm and capabilities of laser welding technology produce very sophisticated results.

In fact, laser welding offers so many advantages that some companies have switched their MIG and other welding applications over to laser welding. 

Fast, Precision-Driven Welding:

The speed and accuracy provided by robotic laser welding solutions is unparalleled. The laser beam creates a very deep and precise weld, without inputting as much heat or energy into the material as is necessary for more traditional welding applications. Because the heat-affected zone is so much smaller, the weldment is more precise.

No Touch-Up Necessary:

Welding without having to constantly rework or refinish? Most welding processes require a touch-up so the seam can look better. Not so with laser welding.  Laser welding is extremely focused, which allows it to weld clean. There isn't the distortion in the base material or seam that you often see with other applications. The resulting weldments are more attractive, making this the perfect application for sheet metal applications that require a clean finished look. Finally, with less refinish/machining work to be done, laser welding is able to provide faster production times.


Laser welding is an attractive option because it is not limited to a specific type of metal. Instead, it is suitable for a variety of different base materials. This adds greater flexibility to the application. In another way, robotic laser welding offers extreme flexibility when it comes to welding hard-to-access parts. The focused laser beam is more direct and less damaging to the material.

Significant productivity gains

Lasermach provide full predefined units to replace any conventional welding system on any robot or automated machine.

Laser welding is an unknown or unexplored option for many manufacturers with automated welding applications, but it is just as easy to implement as other robotic welding systems. The fast travel speeds and low heat input of laser welding makes it especially well-suited for sheet metal welding applications that require precision and attention to aesthetics.

For operations now using MIG, TIG or resistance spot welding, a switch to laser welding can significantly improve productivity — saving time and money while still producing high-quality welds.  Implementing our Wobble-R units in your exisiting Robot welding linne is a piece of cake.


Robotic welding is one of the most common robotic applications in the industrial sector, being driven mainly by the automotive sector for the last several decades. Robotic welding is most productive when completing high-volume, repetitive welding tasks. With the new flexible robots and cobots small batch production and even single part production is in reach of any robot with Wobble-R Fiber laser welding units from Lasermach.

Robotic/Cobotic laser welding has emerged as a highly productive automation solution over the past few years. It offers a number of advantages over traditional welding processes and can be used in completely different types of applications.  
Robotic/Cobotic laser welding delivers precise and clean welds, whereas other methods of welding are more prone to inconsistencies and may leave inaccurate welds, even when paired with robotic automation technology.
Laser welding is also more versatile, working with a wide range of metal thicknesses.
It is normally much faster than traditional welding and has a significantly smaller heat-affected zone, minimizing distortion of the parts during welding.

How Robotic/Cobotic Laser Welding Works

Robotic laser welding works slightly differently than traditional welding methods. There are two types of laser welding: heat conduction laser welding and deep laser welding.

  • Heat conduction laser welding is used primarily for thin parts. In this process, energy gets into the workpiece through heat conduction. The materials melt at the point of the weld from this conducted heat and then quickly solidify, sealing the material.
  • Deep laser welding works by melting the material and creating a deep steam capillary, also known as a keyhole. This steam capillary moves with the laser as the weld is made, allowing the weld to reach deep into the material. The melted material solidifies behind the steam capillary and permanently seals the material.


Robotic laser welding is used in applications that require clean and precise welding. The accuracy and low heat generation of laser welding make it ideal for welding thin or delicate materials without causing distortion or spatter. The manufacture of medical devices, for example, uses laser welding because there’s no material contact, no spatter, and a high degree of weld consistency.

Similarly, robotic laser welding is used in applications that have limited access to the part. Laser welding robots, unlike traditional welding robots, do not actually need to touch the part. Some laser welding robots can weld from over a foot away from the part. This makes accessing hard-to-reach areas much easier.

Robotic laser welding offers a number of benefits over traditional welding in certain applications, depending on the nature of the part. It’s an innovative way to weld metal materials and it’s been gaining popularity in a wide range of industries and applications.

Cost savings

Using laser welding on products with high production volumes, long weld seams and/or many subcomponents results in impressive savings. These savings are primarily due to the high welding speed, the short intervals between the welding and the short changeover times. Furthermore, in cosmetic welds, directly visible to the customer, often manual finishing operations which would be needed after arc welding can be discarded when using laser welding. In industries such as the furniture industry, this can result in very significant cost benefits.

Lightweight materials

The pursuit of a higher output and the use of lightweight materials, such as aluminum and high-grade steel, requires alternative joining methods. Aluminum is much lighter than steel and more affordable than fiber-reinforced plastic or magnesium. The rise in popularity of electric cars increases demand for lightweight solutions, increasing the range of the vehicle and compensating for the weight of the batteries. Laser welding has favorable properties for the joining of aluminum and high-grade steel, such as: low heat input, high welding speed and short intervals between the welding.
