The article deals with the properties of coated electrodes for metal welding produced by UAB Anykščių varis. The newly manufactured electrodes use a standard base putty with a different ferrobor concentration. The main highlights of this work are the search and analysis of literature sources to elucidate the effect of feroboron concentration on the welding process, the performance of the experimental study and analysis of the obtained results to determine the influence of iron boride on the hardness and abrasion resistance of welded metal.
