Laser precision seams
Type LAS coil welding machines

The precise laser transverse seam coil joining machines for flat, high-grade weld seams with coil to coil joints in
various material combinations and with different coil dimensions

IDEAL since 1923 – Your partner for resistance and laser welding machines

As a technology leader, IDEAL has been designing and producing welding machines in Germany since 1923. We offer worldwide service for the maintenance and repair to our customers. The head office situated in Lippstadt (North Rhine-Westphalia) features the administration,
commercial and technical departments as well as the project management and design offices. Our mechanical production is equipped with a modern fleet of machines and delivers high-grade individual components with the greatest of precision.

At the second location in Lippstadt, the machines are assembled in the assembly halls, the hydraulic, pneumatic and electrical systems are installed and subsequently the functional testing is performed. The test operation with customer material is also carried out here in order to prepare the final inspection and training of the customer personnel in an optimal manner.
We seek to meet your expectations.

Type LAS coil welding machines


IDEAL laser transverse seam coil welding machines are in widespread use in the steel coil industry, because they meet and comply with the highest requirements in regard to the weld seam quality.

Leading steel coil manufacturers rely on the IDEAL model line LAS 200 through 500 coil welding machines in order to optimally cut coils in a single operation and to join them without an overhang of the weld seam.

The different types of the LAS line meet all requirements of the steel processing industry and are used at various locations – from the inspection line to the roll train.

IDEAL is always your partner for secure, efficient coil joints.

Quite traditional – laser coil welding machines are utilised in these applications

IDEAL laser coil welding machines are used by leading manufacturers for the welding of coils of various dimensions and materials.

The technology of the laser coil welding machine 


During laser beam welding, the required energy for the joining of materials in the weld zone is applied via the laser radiation.

Laser welding is especially suited where coils are joined with a high welding speed, a narrow and lean weld seam shape and a low thermal distortion.

The advantages of the procedure are the high utilisation factor of the energy applied to the workpiece and its excellent temporal and local control possibilities.

Interfering influences such as distortion, crack formation or embrittlement in the vicinity of the weld seam can be minimised with the utilisation of laser beam welding.

Modular construction – fulfils your requirements


Extensive experience in the design of coil welding systems, a close, cooperative collaboration with our customers, the cooperation with technical universities and research institutes as well as an instinct for technology trends form the foundation of our high innovative strength.

The basis of our development work lies in the continuous further development of our well proven machines with a focus on the best customer benefit and maximum efficiency.

We offer our customers different, modularly constructed model lines of welding machines, which join coils of a wide range of types. In the course of this – to your benefit – particular attention is paid to the versatility and flexibility of the machines.
