The assembly of large structures made out of thick steel plates requires a welding process bywhich multiple wires can be used simultaneously. To reproduce these industrial processes in a researchenvironment, OCAS has invested in a multiwire submerged arc welding (SAW) setup. In this multiwiresetup, up to five wires in tandem configuration can be used.The objective of this master thesis is to establish a deeper knowledge of process parameters used to weldsteel plates in a thickness range of 12,7 up to 25 mm, by means of the submerged arc welding process.Based on literature, a test matrix is composed in which the number of wires, the plate thickness and otherweld parameters are the variables. In addition, a specific plate preparation for each plate thickness isderived from the literature. The preformed weld trails will be evaluated on weld bead geometry andmetallographic properties. There is further experimental examination required, which will result in therevising of the matrix.
