Development of hybrid welding at TRL4 (WP3)
Definition, design, and implementation of facilities for laser hybrid welding at Optoprim.
- Impression of welding cell
- Implementation of laser welding equipment
- Hybrid laser-MAG welding setup
- Laser welding trials using S355 steel grade at Optoprim: effect of laser power, focal plane, fiber diameter, and welding speed on weld penetration
- Example: 6kW, 100µm fibre, 0.5m/min
- Laboratory station for plasma + MAG hybrid welding
- Preliminary bead-on-plate trials with plasma + MAG welding; an increased electrical current in MAG results in an increased depth of penetration
- Butt joint made by plasma + MAG welding; 8mm thick S700MC steel plate
Development of online monitoring at TRL4 (WP4)
Definition and implementation of an online quality monitoring system at Silesian University of Technology
- Overview of data acquisition system
- Laboratory set-up
- Feature extraction during bead-on-plate MAG welding experiments
- Results from plasma arc welding on plates of 8mm and 10mm thickness
Development of predictive tool at TRL4 (WP5)
