In the department of arc welding, fundamental and application-oriented investigations of arc welding processes are carried out. The focus here is on the further development of welding processes and process variants.
In addition, investigations are carried out to clarify physical and metallurgical mechanisms in order to enable modelling of the welding process, weld seam geometry and material properties. With the help of the information gained, automation strategies are developed to enable safe and productive welding production using arc welding.
The experimental work is made possible by extensive laboratory equipment, which includes modern welding power sources, torches and handling equipment as well as various common industrial robots. The methods investigated include all industrially relevant arc welding processes, in particular gas metal arc welding (GMAW), Tungsten inert gas welding (TIGW), Plasma welding (PTA joint welding and Plasma Powder surfacing), Submerged Arc Welding (SAW) and every possible hybrid variant. Furthermore special welding methods for vertical welding of large thick walled components are used. This includes electrogas welding (EG) and electroslag welding (RES). Surface welding of large areas is done through submerged arc strip cladding and electroslag strip cladding.
