Joining and Cutting of Metals
Work of the group focusses on:
- Welding and cutting of metals (pulsed and cw up to 16 kW)
- Laser welding of metals, from thin sheets (< 1 mm) up to thick sheets (> 20 mm)
- Welding of dissimilar materials
- Combining conventional welding processes with laser processing (hybrid welding)
- Processing of thermally sensitive materials and components
Current scientific work and projects:
- DOVOR „Reliable, high-power welding of high-strength, fine grain structural steels using a hybrid welding process with integrated, inductive pre-heating” (AiF)
- Laser hybrid welding of steel materials (currently up to 22 mm thickness) with inductive pre-heating
- Generation of high welding depths in combination with high feed rates
- StAlKo “Laser welding of steel and aluminum using a spectroscopic control of the welding depth and increased joint width with two-dimensional welding seams” (AiF/FAT)
- Laser welding of dissimilar materials – aluminum and steel – for lightweight construction for resource conservation
- Spectroscopic control of the welding depth for quality assurance
- SFB 599 „Implants with variable stiffness “ (DFG)
- Further development of NiTi-based shape memory alloy (SMA) implants
- Establishment of cw laser welding for NiTi SMAs
- KoSoFla „Cost reduction for the production of solar absorbers for flat-plate collectors (AiF)
- Laser welding of non-similar metals (copper/aluminum and copper/steel) to cost-optimize the manufacturing process of solar absorbers
- AlDi “Development of an electrical feedthrough with a high-vacuum-tight, mechanically stable aluminum flange” (ZIM)
- Laser welding of dissimilar materials (aluminum, copper, steel and nickel-based materials) to generate components which are high-vacuum-tight
- Laser welding of dissimilar materials (aluminum, copper, steel and nickel-based materials) to generate components which are high-vacuum-tight
