- Abstract
In order to ensure the quality of welded pressure vessels joints and optimise the submerged arc welding process it is necessary to have an appropriate welding speed that can guarantee a strong welded pressure vessel product. The main parameter that can be manipulated in order to optimize the welding process, in this case, is the welding speed. Increasing the welding speed results in increasing productivity but the quality of the welding joints can be affected. This study presents how the welding speed influences the tensile strength of the welded joints from pressure vessel steel. There are treated aspects such as the dimensions, geometry of the welded seam and breaking stress occurred in stretching of the welded joints. The test specimens were created by using the submerged arc welding technology, and the welding process was realized by using a semiautomatic industrial submerged arc welding machine. The pressure vessel steel used as a base material is P355 N.
