ANDRITZ Soutec developed the innovative SOUTRAC II, today’s world’s most advanced tailored blank laser welding system for complex, curved seams in car body parts. The core piece is the unique 15-axes processing head, which makes the system capable of welding small radii and polynomial seams.

The unique technology optimizes weld seam path engineering for ideal force transmission during the downstream forming process. This is only possible because the system is capable of highly dynamic tracking of seam paths with small radii, combined with the ability to react constantly and quick to varying gap situations. The new high-tech core piece incorporating 15 axes in combination with a welding shuttle concept is now implemented into the new generation of the SOUTRAC II welding system. The continuous measurement seam tracking and quality control system guarantees a stable welding process, meeting the highest quality requirements. Gaps of <0.5 mm between the sheet metal are closed adaptively with SOUFIL® wire and the patented SOUGAP® beam shaping technology.

SOUTRAC II makes it possible to achieve the maximum effect in terms of weight reduction and crash performance of vehicles and resulting in greater passenger safety and improved environmental protection.
