In this article the changes of seams properties of steel S235J2(LST EN 10025:2004) were analyzed, produced by welding withdifferent technology are discussed. Samples were welded byhand arc welding, using AV-23 and AV-66 welding electrodes.The welded seams were made by changing short-circuit current.The duration of weld depth, ridge height, metal drop size, metaldrop frequency, short-circuit time and short-circuit current valueare determinated.The results of the research are given in graphs,final conclusions are also written.
