Besides speed and precision, laser welding offers high productivity, new construction possibilities and cost savings. In order to guarantee a fast-welding speed and a reliable process, the product design, jig design, integrated airflow and other preconditions must be of the highest quality. Moreover, innovation is deeply rooted in our DNA, leading to very successful projects for our customers.
With over 17 years of experience and 180 laser welding machines sold, which have already produced millions of high-quality parts, AWL is the ideal partner for you. Examples of industries in which these machines operate: car seats, body-in-white components, tubular products such as fittings, industrial cabinets and batteries.
The design and construction of a laser welding machine requires broad knowledge of many aspects of both welding and machine building. After a consultation or workshop, we can manufacture test parts in our Experience Center using our very high-powered laser welding machine. There, our experts make their knowledge available to your project.
The heart of each welding machine is the jig. AWL has extensive experience in designing stable and reliable jigs. For the machines, AWL integrates the most advanced components and is open to the integration of various brands of lasers and robots. This enables us to adapt as well as possible to the customer’s requirements.
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 boosts 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.
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.
In the past, most laser welds were overlapping seams. In recent years, AWL has successfully focused on adding non-overlapping laser welding with industrial robots to the portfolio. The unique software tool we developed, the AWL GeoEditor, enables simple robot programming for these demanding applications.
At AWL, experts work continuously on the further optimization of the machines. These innovations include improving productivity, such as the latest developments in the field of robotic laser welding – laser welding with a scanner head on a moving robot – or improving quality, for example in laser welding that is optimized with CFD (Computational Fluid Dynamics) technologies, in which the flow of air required for a high welding speed is optimized by means of numerical simulations.
