Research Activities
The hybrid welding laboratory of Politecnico di Bari is a hightech laboratory devoted to the joining and powderless additive processes of metals and metal alloys. The laboratory is equipped with 3 different welding techniques which are High Power Ytterbium Laser (HPYL), Friction Stri Welding FSR), and Arc Welding (AW). Those technologies are combined for hybrid welding by coupling two techniques at any time. Single plus coupled techniques account for 6 different options for solving welding problems.
The team of HWL furnish on demand study and consulting on enhancing productivity, lower cost, speed up throughput. The solution can reduce distortion, post-weld rework, and enhance weld quality. Stronger, lighter, better end-products and new product can be designed using the power for fusion and solid-state welding and fabrication technique. The fabrication of dissimilar metals welded structure is one of the major success of the laboratory.
The services includes also metallurgical, mechanical characterisations and numerical simulation.
