Abstract

The selection procedure and qualification of the optimal welding technology for the structural steel S355J2G3 are presented in this paper. The considered steel is widely applied for manufacturing the supporting structures in various areas, especially in civil and mechanical engineering. It is delivered mainly in form of plates of various thicknesses and solid profiles of various diameters. Considering that welding is mostly used in manufacturing of structures, it is very important to be aware of possibilities for this steel welding, as well as of problems that may arise during that process. Here are presented: a calculation procedure of the base metal's weldability, selection of the filler metal and the welding technology, with results of experimental testing of the base metal and welded samples. The following experimental investigations were performed: tensile, bending and impact toughness test, metallographic investigations and hardness measurement. All the samples were cut out from the welded plates. Obtained results have shown that the structural steel S355J2G3 is suitable for welding, since there is no danger of appearance of cracks or other defects. With adequate choice of the welding technology the mechanical properties of the welded joint can be comparable to those of the base metal. © Published under licence by IOP Publishing Ltd.
