“…The development of modern structural materials satisfying high quality-related, functional and strength-related requirements results from the need for designing and manufacturing structural steels and special vehicles used both in military and civilian applications. Until today, commonly used steels include toughened (hardened and tempered) steels having a yield point of up to 1300 MPa [1], TMCP steels having a yield point of up to 1100 MPa and steels used in ballistic shields, characterised by hardness below 550 HB [2]. These three groups of structural materials are characterised by high mechanical properties and weldability (if made in a manner satisfying related technological recommendations) [2,3].…”

As the above-named steels have been used and known for many years, their properties are beginning to fail to meet demands of design engineers, e.g.…”

Intense research on the metallurgy of iron alloys have recently resulted in the development of technologies enabling the making of high-carbon nanobainitic steels. Because of their chemical composition, the above-named steels belong to hard-to-weld materials. To identify the possibility of welding such steels using arc-based methods and welding in the solid state it was necessary to make test joints and perform related metallographic tests. The test results revealed that it is possible to obtain both fusion and pressure welded joints if the process was performed in the softened state, i.e. before the final heat treatment. Afterwards, joints should be subjected to a heat treatment ensuring the obtainment of a previously assumed microstructure and required hardness distribution in the weld and HAZ.
