“…Welding is one of the oldest technologies in the world. Ancient weapons made more than a thousand years ago can serve as the evidence of how old the welding technology is [ 1 ]. Nowadays, welding plays an outstanding role in industry and is used in such sectors as construction and building, transportation, energy, and others [ 2 , 3 ].…”

The purpose of the research was to obtain an arc welded joint of a preliminary quenched high-carbon wear resistant steel without losing the structure that is previously obtained by heat treatment. 120Mn3Si2 steel was chosen for experiments due to its good resistance to mechanical wear. The fast cooling of welding joints in water was carried out right after welding. The major conclusion is that the soft austenitic layer appears in the vicinity of the fusion line as a result of the fast cooling of the welding joint. The microstructure of the heat affected zone of quenched 120Mn3Si2 steel after welding with rapid cooling in water consists of several subzones. The first one is a purely austenitic subzone, followed by austenite + martensite microstructure, and finally, an almost fully martensitic subzone. The rest of the heat affected zone is tempered material that is heated during welding below A1 critical temperature. ISO 4136 tensile tests were carried out for the welded joints of 120Mn3Si2 steel and 09Mn2Si low carbon steel (ASTM A516, DIN13Mn6 equivalent) after welding with fast cooling in water. The tests showed that welded joints are stronger than the quenched 120Mn3Si2 steel itself. The results of work can be used in industries where the severe mechanical wear of machine parts is a challenge.

The analysis of early Medieval swords is of great significance due to the eminent position of the find category in the study of the early Medieval period. X-ray computed tomography is a non-destructive analytical method permitting the collection of data that otherwise could only be gathered with considerable effort and much damage to the object. Beyond the usual morphological and dimensional parameters, the method allows for the fast and accurate gathering of knowledge about the construction and manufacturing processes of sword blades and can also be applied to block-lifted swords. Preservation condition and related artifacts caused by beam hardening may be limiting factors; however, in most instances interpretation of the data remains possible.
