Abstract
This study investigates the influence of the soft zone on the static tensile strength of welded joints. A micro-alloyed, thermo-mechanically controlled processed (TMCP) high strength low alloy steel grade (HSLA) was joined with electron beam welding at different energy input levels. The welded joints were investigated by means of light optical microscopy, FE-SEM (field emission scanning electron microscopy) analyse, hardness measurement and quasi- static tensile test. The results of this investigation were compared with the mechanical properties of GMAW welded joints of same base metal.
