TSI AdditiveLab

Advanced Manufacturing R&D

AdditiveLab is a dedicated research and development (R&D) unit within the Transport and Telecommunication Institute. We specialize in metal wire additive manufacturing, robotic welding, and industrial automation.

Our mission is to connect academic research with practical industrial application. We develop industrial solutions—from initial concept to final implementation—and create custom software for our systems.

Our projects

Welding technology for thin stainless steel parts

Reliable and accurate MIG welding technology for a challenging 0.5 mm thick stainless steel welding. The project included complete research and development, iterative testing of custom fixtures types, and extensive work with specialized process parameters and cyclograms. The resulting process is capable of welding with up to 1 mm gap while maintaining full material integrity and defect-free weldments. The final technology was validated through laboratory testing and statistical results evaluation, including X-ray, UTS testing and macrostructure analysis.

Adaptive robotic welding of construction box frames

Fully adaptive robotic welding system for manufacturing large, complex construction box frames. The project integrates a multi-axis kinematic system with custom software to optimize the welding sequence, minimize deformation, and ensure high-quality, repeatable results. Technology was implemented using a welding robot on a 3-axis gantry with a linear track and a 2-axis workpiece positioner for full access to complex geometries. To compensate for part assembly deviations, touch-sensing technology was set on the robot to detect variations and automatically adapt the weld path. A custom welding sequence was developed to control heat input, minimizing deformation and residual stress. The system also includes a user-friendly operator’s panel and an automatic torch cleaning sequence.
