Arc welding

Arc welding and the procedures typically involved are often used in industry due to the wide range of welding tools and power sources from major manufacturers. 

• Investigation and further development of arc welding using compressed air towards cutting pollutant emissions
• High-butt weld – load capacity of butt welds on high-strength steel in steel construction
• Welding cladded plates and hardfacing shaped around the joint seam
• Welding on hollow sections with widened joint seams

• Robotic welding on pipe nodes
• High-performance welding processes for offshore applications
• Thermal straightening on stiffened plate structures using induction heating
• Cost-effective welding on thick-walled tubing in wind turbine structures
• Cost-effective technologies for welding profiles and pipe segments in high-strength steel by determining heat input
• Development of a lightweight rotor for run-of-river (ROR) hydroelectric power plants         Development of an innovative application-oriented system for induction-preheating aluminium alloys and ultra-high-strength fine-grain structural steel in fully mechanised arc welding
• Alloying systems for cored wire in MIG/MAG welding on aluminium-based wrought and die-cast alloys
• Fatigue-resistant trusses made of hollow tubes with thick-walled straps
• FOLUREN project for welding joins in lightweight rotors made of composite materials
• Development of a camera system for online process control and visual assessment of selected arc coating processes; development of an online visual process control method in selected arc coating processes
• Plasma cutting on stainless steel
• Mechanised welding on complex contours in large-volume components
• Application options and limitations in plasma marking for stable welded structures
• Hardness on flame-cut edges and beam welds

• Research projects (publicly funded)
• Industrial research
• Industrial services on commission (repair welding, deposition welding, inspections on gas-shielded welding wires, TIG and MIG/MAG series welding, torch tests, welding on shop primers, assessments, etc.)
• Technology and process development
• Technological consultation
